CONDITIONALS

Definition: The conditional tense says that an action is reliant on something else. The conditionals are used to talk about real or unreal situations, they are sometimes called if-clauses. Real Conditional describes real-life situations. Unreal Conditional describes unreal, imaginary situations.

For example: If a certain condition is true, then a particular result happens.

There are four basic conditionals that we use in English.
  • Zero Conditional
  • First Conditional
  • Second Conditional
  • Third Conditional

    * There are some more conditionals formed by mixing some of these four.
Structure of Conditional Sentences
The Zero Conditional is used for actions that are always true when the conditions are satisfied. The structure of the conditionals is straightforward. There are two basic possibilities in terms of order in the sentence:
IF
Condition
Result
If
it rains,
we will get wet
Result
IF
Condition
we will get wet
If
it rains,

* Notice that we only use a comma in the first example.

Conditionals: Time and Probability Table
Probability
Conditional
Example
Time
Certain
zero conditional
If you heat water to 100 degrees celsius, it boils
any time
Likely
first conditional
If it rains, I will stay in.
future
Unlikely
second conditional
If I won the lottery, I would retire.
future
Impossible
second conditional
If I had the money, I would lend it to you
present
Impossible
third conditional
If I had seen him, I would have given him the message.
past

Zero Conditional: Certainty
The Zero conditional is used for things that are always true as long as the condition is met.

Formation:
if + present simple, + present simple
IF
Condition
Result
Situation

present simple
present simple

If
you heat water to 100 degrees celsius,
it boils.
fact- universal

present simple
present simple

If
I drink coffee,
I get a headache.
fact- personal

In these examples, the result will always occur if the condition is met, so the time is not important.

First Conditional: A real possibility in the future
A First Conditional sentence is for future actions dependent on the result of another future action or event, where there is a reasonable possibility of the conditions for the action being satisfied.

Formation:
if + present simple, + will

For example: If she gets good grades, she will go to university.

We are talking about the future, but we use a present tense for the condition and will for the result. In this case, the person is sure about going to university. We can use other modal verbs in the result part of the sentence. For example:
IF
Condition
Result
Possibility
If
she gets good grades,
she will go to university.
If the condition is met, then she definitely will go
If
he gets good grades,
he may go to university.
He is not sure about going to university.
If
she gets good grades,
she should go to university.
The speaker is expressing his or her opinion, giving advice.
If
he gets good grades,
he can go to university.
This means that it is possible.
If
she gets good grades,
she could go to university.
This means that it is possible, but not that likely.
If
he gets good grades,
he might go to university.
This means that it is possible, but not that likely.
We can also use different present forms in the condition part of the sentence like: present simple, present progressive, present perfect, etc
Second Conditional: Imaginary Present or Unlikely Future
The Second Conditional can be used used to talk about imaginary present situations, where we are imagining something different from what is really the case. We can also use it to talk about things in the future that are unlikely to happen, as the condition is unlikely to be met. We use the past tense in the condition part and would for the result.

Formation: if + past simple, + would + base form

For Example: If I were you, I'd tell her.
IF
Condition
Time
Result
Possibility

past simple
present
WOULD + base verb
impossible
If
I had the time,

I would learn Italian.
I don't have the time, so I'm not going to learn Italian.

past simple
future
WOULD + base verb
Unlikely
If
I won the lottery

I would travel around the world.
There's a very small chance of winning the lottery, so the trip is unlikely
We can use other modal verbs in the past tense in the result part of the sentence:
IF
Condition
Result
Certainty

past simple
WOULD + base verb

If
I had the time,
I would learn Italian.
Although unlikely to happen, the speaker is sure that they would do it given the opportunity.
If
I had more time,
I might learn English.
Although unlikely to happen, it is only a possibility anyway.
If
I had more time,
I should learn some more about IT.
Although unlikely to happen, the speaker is saying that it would be a good idea, but is not committed to it.
If
I had more time
I could learn Hindi.
Although unlikely to happen, it is only a possibility anyway.
Third Conditional: Imaginary Past The third conditional is used when we are talking about the past and imagining something different from what actually happened, that means for imaginary past actions, where the conditions for the action WERE NOT satisfied.
Formation: if + past perfect, + would have + past participle
For example: If I had known, I would have helped. I didn't know and didn't help.
IF
Condition
Result
Certainty

past perfect
WOULD HAVE+ past participle

If
I had known,
I would have helped.
Although this didn't happen, the speaker is sure about the result.
If
I had known,
I could have helped.
Although this didn't happen, the result is only a possibility.
If
I had known,
I might have helped.
Although this didn't happen, the result is only a possibility.
If
you had known,
you should have helped.
Although this didn't happen, it is only a good suggestion or piece of advice.
Third Second Mixed Conditionals For imaginary present actions or situations that are not possible because the necessary conditions were not met in the past.
Formation: if + past perfect, + would + base form
For example:
  • If you had taken the course, you would know about it. (The conditions were not met because the person did not do the course and as a result does not know about it now.)
Second Third Mixed Conditionals To avoid the illogicality of saying 'If I had been you', which means that I was not you on that occasion, but could be in the future, which is, of course, impossible.
Formation: if + past simple, + would have + past participle
For example:
  • If I were you, I wouldn't have done that.
When the first part is still true
For example:
  • If I could speak English, I wouldn't have needed to get the letter translated. (This means that I couldn't speak English then when I needed the translator and still can't)

Past Conditionals

Past Real Conditional

FORM

[If / When ... Simple Past ..., ... Simple Past ...]
[... Simple Past... if / when ... Simple Past ...]
USE

The Past Real Conditional describes what you used to do in particular real-life situations. It suggests that your habits have changed and you do not usually do these things today.
Examples:
· If I went to a friend's house for dinner, I usually took a bottle of wine or some flowers. I don't do that anymore.
· When I had a day off from work, I often went to the beach. Now, I never get time off.
· If the weather was nice, she often walked to work. Now, she usually drives.
· Jerry always helped me with my homework when he had time. But he doesn't do that anymore.
· A: What did you usually do when it rained?
B: I usually stayed at home.
IMPORTANT Used to

The form "used to" expresses the idea that something was an old habit that stopped in the past. This form is commonly used in Past Real Conditional sentences to emphasize that something was a habit. The examples below have the same meaning as the examples above.
Examples:
· If I went to a friend's house for dinner, I used to take a bottle of wine or some flowers. I don't do that anymore.
· When I had a day off from work, I used to go to the beach. Now, I never get time off.
· If the weather was nice, she used to walk to work. Now, she usually drives.
· Jerry used to help me with my homework when he had time. But he doesn't do that anymore.
· A: What did you usually do when it rained?
B: I used to stay at home.
IMPORTANT If / When

Both "if" and "when" are used in the Past Real Conditional. Using "if" suggests that something happened less frequently. Using "when" suggests that something happened regularly.
Examples:
· When I had a day off from work, I usually went to the beach.
I regularly had days off from work.
· If I had a day off from work, I usually went to the beach.
I rarely had days off from work.
Past Unreal Conditional

FORM

[If ... Past Perfect ..., ... would have + past participle ... ]
[... would have + past participle ... if ... Past Perfect ...]
USE

The Past Unreal Conditional is used to talk about imaginary situations in the past. You can describe what you would have done differently or how something could have happened differently if circumstances had been different.
Examples:
· If I had owned a car, I would have driven to work. But I didn't own one, so I took the bus.
· She would have traveled around the world if she had had more money. But she didn't have much money, so she never traveled.
· I would have read more as a child if I hadn't watched so much TV. Unfortunately, I did watch a lot of TV, so I never read for entertainment.
· Mary would have gotten the job and moved to Japan if she had studied Japanese in school instead of French.
· If Jack had worked harder, he would have earned more money. Unfortunately, he was lazy and he didn't earn much.
· A: What would you have done if you had won the lottery last week?
B: I would have bought a house.

· A: What city would you have chosen if you had decided to move to the United States?
B: I would have chosen
Seattle.
IMPORTANT Only use "If"

Only the word "if" is used with the Past Unreal Conditional because you are discussing imaginary situations. "When" cannot be used.
Examples:
· I would have bought that computer when it had been cheaper. Not Correct
· I would have bought that computer if it had been cheaper. Correct
EXCEPTION Conditional with Modal Verbs

There are some special conditional forms for modal verbs in English:
would have + can = could have
would have + shall = should have
would have + may = might have
The words "can," "shall" and "may" cannot be used with "would have." Instead, they must be used in these special forms.
Examples:
· If I had gone to Egypt, I could have learned Arabic.
· If she had had time, she might have gone to the party.
The words "could," should," "might" and "ought to" include Conditional, so you cannot combine them with "would have."
Examples:
· If I had had more time, I could have exercised after work.
· If he had invited you, you might have gone.
Mixed Conditionals

Those of you who have been following the Conditional Tutorial should now be familiar with present, past and future conditional verb forms. Sometimes Unreal Conditional sentences are mixed. This means that the time in the if-clause is not the same as the time in the result. Study the examples below to learn how to mix conditional verb forms like a native speaker.
Verbs in green are in the Present Unreal Conditional.
Verbs in red are in the Past Unreal Conditional.
Verbs in purple are in the Future Unreal Conditional.
Mixed Conditional Patterns

PAST
PRESENT
Examples:
· If I had won the lottery, I would be rich.
But I didn't win the lottery in the past and I am not rich now.
· If I had taken French in high school, I would have more job opportunities.
But I didn't take French in high school and I don't have many job opportunities.
· If she had been born in the United States, she wouldn't need a visa to work here.
But she wasn't born in the United States and she does need a visa now to work here.
PAST
FUTURE
Examples:
· If she had signed up for the ski trip last week, she would be joining us tomorrow.
But she didn't sign up for the ski trip last week and she isn't going to join us tomorrow.
· If Mark had gotten the job instead of Joe, he would be moving to Shanghai.
But Mark didn't get the job and Mark is not going to move to Shanghai.
· If Darren hadn't wasted his Christmas bonus gambling in Las Vegas, he would go to Mexico with us next month.
But Darren wasted his Christmas bonus gambling in Las Vegas and he won't go to Mexico with us next month.
PRESENT
PAST
Examples:
· If I were rich, I would have bought that Ferrari we saw yesterday.
But I am not currently rich and that is why I didn't buy the Ferrari yesterday.
· If Sam spoke Russian, he would have translated the letter for you.
But Sam doesn't speak Russian and that is why he didn't translate the letter.
· If I didn't have to work so much, I would have gone to the party last night.
But I have to work a lot and that is why I didn't go to the party last night.
PRESENT
FUTURE
Examples:
· If I didn't have so much vacation time, I wouldn't go with you on the cruise to Alaska next week.
But I do have a lot of vacation time and I will go on the trip next week.
· If Cindy were more creative, the company would send her to New York to work on the new advertising campaign.
But Cindy is not creative and the company won't send her to New York to work on the new campaign.
· If Dan weren't so nice, he wouldn't be tutoring you in math tonight.
But Dan is nice and he is going to tutor you tonight.
FUTURE
PAST
Examples:
· If I weren't going on my business trip next week, I would have accepted that new assignment at work.
But I am going to go on a business trip next week, and that is why I didn't accept that new assignment at work.
· If my parents weren't coming this weekend, I would have planned a nice trip just for the two of us to NapaValley.
But my parents are going to come this weekend, and that is why I didn't plan a trip for the two of us to NapaValley.
· If Donna weren't making us a big dinner tonight, I would have suggested that we go to that nice Italian restaurant.
But she is going to make us a big dinner tonight, and that is why I didn't suggest that we go to that nice Italian restaurant.
FUTURE
PRESENT
Examples:
· If I were going to that concert tonight, I would be very excited.
But I am not going to go to that concert tonight and that is why I am not excited.
· If Sandywere giving a speech tomorrow, she would be very nervous.
But Sandy is not going to give a speech tomorrow and that is why she in not nervous.
· If She didn't come with us to the desert, everyone would be very disappointed.
But She will come with us to the desert and that is why everyone is so happy.
Continuous Conditionals

Those of you who have studied Englishpage.com's Verb Tense Tutorial should be familiar with continuous verb tenses such as Present Continuous, Past Continuous, Future Continuous, Present Perfect Continuous, Past Perfect Continuous, and Future Perfect Continuous. The Verb Tense Tutorial gives you all the information you need to create continuous Real Conditional sentences. But many English learners are not aware of the fact that we can use continuousness in imaginary situations as well. Study the examples below to learn how to create continuous Unreal Conditional sentences that will make you sound like a native speaker.
Present Unreal Conditional + Continuous

FORM

If-clause: [were + present participle]
Result: [would be + present participle]
USE

Present Unreal Conditional + Continuous is used to discuss imaginary situations which could be happening at this very moment.
Examples in the if-clause:
· If the sun were shining, I would go to the beach.
Unfortunately, it is raining so I can't go.
· If Sam were sitting here, we would be able to ask him the question ourselves.
But Sam is not sitting here. He is somewhere else.
· We would be able to go sailing if the wind were blowing.
But there is no wind, so we can't go sailing.
Examples in the result:
· If I were in Hawaii, I would be lying on the beach.
But I am not in Hawaii.
· If my grandfather were here, he would be talking about the war.
But he is not here.
· I would be rafting down the Colorado River right now if my leg weren't broken.
But my leg is broken, so I am not there.
Past Unreal Conditional + Continuous

FORM

If-clause: [had been + present participle]
Result: [would have been + present participle]
USE

Past Unreal Conditional + Continuous is used to discuss imaginary situations happening at a very specific time in the past or over a period of time in the past.
Examples in the if-clause:
· If I had been talking to him when he said that, I would have punched him in the face.
But I wasn't talking to him when he said that.
· If he had been standing near the house when the wall collapsed, it would have killed him.
Luckily, he moved away before the wall fell.
Examples in the result:
· If you had gone to his house last night, he would have been sitting on his couch in front of the TV.
But you didn't go to his house, so you didn't see what he was doing.
· If she had missed her train, he would have been waiting for her at the station for hours.
Luckily, she caught her train and he didn't have to wait.
NOTICE that the Past Unreal Conditional + Continuous can be used like the Past Continuous in imaginary situations to emphasize interruptions or parallel actions in the past.
Examples in the if-clause:
· If James had been crossing the street when the car ran the red light, it would have hit him.
· If Tom had been studying while Becky was making dinner, he would have finished his homework early and they could have gone to the movie.
Examples in the result:
· If James hadn't stopped to tie his shoe, he would have been crossing the street when the car ran the red light.
· If you had gone to their house last night, Bob would have been reading the newspaper, Nancy would have been talking on the phone and the kids would have been watching TV. They always do the same things.
NOTICE that Past Unreal Conditional + Continuous can also be used like Present Perfect Continuous or Past Perfect Continuous in imaginary situations to emphasize a duration of time.
Examples in the if-clause:
· Scott said he had been studying Greek for more than five years. If he had been studying the language that long, I think he would have been able to interpret for us at the airport.
· Sarah claimed she had been waiting in the rain for more than twenty minutes by the time we arrived, but she wasn't even wet. If she had been waiting that long, I think she would have been totally drenched by the time we arrived.
Examples in the result:
· Terry's plane arrived ahead of schedule. If I hadn't decided to go to the airport early, she would have been waiting there for more than twenty minutes before I arrived.
· At the travel agency yesterday, I waited for more than an hour for somebody to help me. Finally, I got up and left. If I hadn't decided to leave, I would have been sitting there forever.
Future Unreal Conditional + Continuous

FORM

If-clause: [were + present participle]
Result: [would be + present participle]
USE

Future Unreal Conditional + Continuous can be used like the Future Continuous in imaginary situations to emphasize interruptions or parallel actions in the future.
NOTICE The future form looks the same as the present form. The future is indicated with words such as "tomorrow," "next week" or "in a couple of days."
Examples in the if-clause:
· If I were waiting there next week when he gets off the plane, he would be totally surprised.
But I will not be waiting there, so he won't be surprised.
· If he were staying in that hotel next week while the conference is being held, he might be able to meet some of the key speakers and tell them about our new product.
I don't think he will be able to stay at the hotel, so he won't be able to meet anybody there.
Examples in the result:
· If I were able to go to the train station tonight to meet Sandra, I would be standing on the platform waiting for her when she arrives.
I won't be able to go to the train station, so I will not be standing there when she arrives.
· If you went over to Paul's house after work, he would probably be sitting there at his computer surfing the Internet.
But you won't go over.
Were To

"Were to" in the Present

FORM

[If ... were to + verb ..., ...]
USE

"Were to" can be used in the present to emphasize that the conditional form is extremely unlikely or unthinkably horrible. Notice that this special form is only used in the if-clause.
Examples:
· If she were to be rich, she would be horribly obnoxious.
It is very unlikely that she would be rich.
· If I were to have no friends, who would I spend my time with?
Having no friends is a horrible thought.
· If Nathan were to be my boss, this job would be intolerable.
Nathan's being my boss is a horrible concept.
"Were to" in the Future

FORM

[If ... were to + verb ..., ...]
USE

"Were to" can be used in the future to emphasize that the conditional form is extremely unlikely or unthinkably horrible. Notice that this special form is only used in the if-clause.
Examples:
· If I were to lose my job next year, I would probably not find a new one quickly.
Loosing my job would be terrible.
· If he were to fail his driving test tomorrow, he would have to take it again.
He is not likely to fail his driving test.
· If Sarah were to show up late to the birthday party, it would ruin the surprise.
Sarah will surely come on time.
"Were to" in the Past

FORM

[If ... were to have + past participle ..., ...]
USE

"Were to" can be used in the past to emphasize that the conditional form is extremely unlikely or unthinkably horrible. Notice that this special form is only used in the if-clause.
Examples:
· If the fire were to have destroyed the building, it would have been a tragic cultural loss.
The thought of such a loss is too horrible to consider.
· If the dam were to have burst, the entire town would have been destroyed.
Such destruction is too horrible to consider.
· If Sarah were to have failed the final test, she would have lost her scholarship.
She is an excellent student, and it is very unlikely that she would have failed the test.
Future Conditionals

Future Real Conditional

FORM

[If / When ... Simple Present ..., ... Simple Future ...]
[... Simple Future ... if / when ... Simple Present ...]
Notice that there is no future in the if- or when-clause.
USE

The Future Real Conditional describes what you think you will do in a specific situation in the future. It is different from other Real Conditional forms because, unlike the present or the past, you do not know what will happen in the future. Although this form is called "real", you are usually imagining or guessing about the future. It is called "real" because it is still possible that the action might occur in the future. Carefully study the following examples and compare them to the Future Unreal Conditional examples further down the page.
Examples:
· If I go to my friend's house for dinner tonight, I will take a bottle of wine or some flowers.
I am still not sure if I will go to his house or not.
· When I have a day off from work, I am going to go to the beach.
I have to wait until I have a day off.
· If the weather is nice, she is going to walk to work.
It depends on the weather.
· Jerry will help me with my homework when he has time.
I have to wait until he has time.
· I am going to read if there is nothing on TV.
It depends on the TV schedule.
· A: What are you going to do if it rains?
B: I am going to stay at home.
IMPORTANT If / When

Both "if" and "when" are used in the Future Real Conditional, but the use is different from other Real Conditional forms. In the Future Real Conditional, "if" suggests that you do not know if something will happen or not. "When" suggests that something will definitely happen at some point; we are simply waiting for it to occur. Notice also that the Simple Future is not used in if-clauses or when-clauses.
Examples:
· When you call me, I will give you the address.
You are going to call me later, and at that time, I will give you the address.
· If you call me, I will give you the address.
If you want the address, you can call me.
Future Unreal Conditional

FORM 1 (Most Common Form)

[If ... Simple Past ..., ... would + verb ...]
[... would + verb ... if ... Simple Past ...]
Notice that this form looks the same as Present Unreal Conditional.
USE

The Future Unreal Conditional is used to talk about imaginary situations in the future. It is not as common as the Future Real Conditional because English speakers often leave open the possibility that anything MIGHT happen in the future. It is only used when a speaker needs to emphasize that something is impossible. Because this form looks like Present Unreal Conditional, many native speakers prefer Form 2 described below.
Examples:
· If I had a day off from work next week, I would go to the beach.
I don't have a day off from work.
· I am busy next week. If I had time, I would come to your party.
I can't come.
· Jerry would help me with my homework tomorrow if he didn't have to work.
He does have to work tomorrow.
FORM 2

[If ... were + present participle ..., ... would be + present participle ...]
[... would be + present participle ... if ... were + present participle ...]
USE

Form 2 of the Future Unreal Conditional is also used to talk about imaginary situations in the future. Native speakers often prefer this form over Form 1 to emphasize that the conditional form is in the future rather than the present. Also notice in the examples below that this form can be used in the if-clause, the result, or both parts of the sentence.
Examples:
· If I were going to Fiji next week, I would be taking my scuba diving gear with me. In if-clause and result
I am not going to go to Fiji and I am not going to take my scuba gear with me.
· If I were not visiting my grandmother tomorrow, I would help you study. In if-clause
I am going to visit my grandmother tomorrow.
· I am busy next week. If I had time, I would be coming to your party. In result
I am not going to come to your party.
FORM 3

[If ... were going to + verb ..., ... would be + present participle ...]
[... would be + present participle ... if ... were going to + verb ...]
USE

Form 3 of the Future Unreal Conditional is a variation of Form 2 which is also used to talk about imaginary situations in the future. Notice that this form is only different from Form 2 in the if-clause. Native speakers use Form 3 to emphasize that the conditional form is a plan or prediction in the same way "be going to" is used to indicate a plan or prediction.
Examples:
· If I were going to go to Fiji next week, I would be taking my scuba diving gear with me.
I am not going to go to Fiji and I am not going to take my scuba gear with me.
· If I were not going to visit my grandmother tomorrow, I would help you study.
I am going to visit my grandmother tomorrow.
IMPORTANT Only use "If"

Only the word "if" is used with the Past Unreal Conditional because you are discussing imaginary situations. "When" cannot be used.
Examples:
· I would buy that computer tomorrow when it were cheaper. Not Correct
· I would buy that computer tomorrow if it were cheaper. Correct
EXCEPTION Conditional with Modal Verbs

There are some special conditional forms for modal verbs in English:
would + can = could
would + shall = should
would + may = might
The words "can," "shall" and "may" cannot be used with "would." Instead, they must be used in these special forms.
Examples:
· If I went to Egypt next year, I would can learn Arabic. Unfortunately, that's not possible. Not Correct
· If I went to Egypt next year, I could learn Arabic. Unfortunately, that's not possible. Correct
The words "could," should," "might" and "ought to" include conditional, so you cannot combine them with "would."
Examples:
· If I didn't have to work tonight, I would could go to the fitness center. Not Correct
· If I didn't have to work tonight, I could go to the fitness center. Correct
Future Real Conditional vs. Future Unreal Conditional

To help you understand the difference between the Future Real Conditional and the Future Unreal Conditional, compare the examples below:
Examples:
· If you help me move tomorrow, I will buy you dinner. Future Real Conditional
I don't know if you can help me.
· If you helped me move tomorrow, I would buy you dinner. Future Unreal Conditional
You can't help me, or you don't want to help me.
Conditional Types

The conditional sentence in English can be seen in terms of three principal types.
Type I

We use this type to imply that it is likely that the action in the if-clause will be performed. This kind is structured as follows:
If-clause
main clause
Verb in the present tense
Verb in the future tense
If you work hard,
you will succeed.

It is still probable that you will succeed if the condition (to work hard) is fulfilled.
N.B. The verb in the if-clause is never in the future.
Verb in the present tense
verb in the imperative
If you want to take a photo,
press this button.
Type II

This type however is used to indicate that the idea is improbable or unreal. The result of the condition is imaginary. It is structured as follows:
If-clause
main clause
Simple past tense (subjunctive)
conditional tense (would do etc.)
If she had wings,
she would fly.
N.B.: It is more a wish than anything probable to occur.
Type III

It is an impossible condition. The structure is as follows:
If-clause
main clause
Past perfect tense
perfect conditional
If + past perfect
should / would have done
If she had been tall enough,
she would have been recruited.
This implies that she was not tall enough that's why she wasn't recruited. It is impossible because the sentence refers to past events that had already finished.
Type Zero

Some scholars add a fourth basic kind which they refer to as "Zero conditional" or "Conditional type Zero", which I cannot recognize as such because its structure can in no way be considered conditional. The conditional, roughly speaking, means the uncertain whereas this type of conditional mostly deals with facts. The reasons if I have to name some are,
1. The result is always a fact. E.g. If you drop sugar into water, it melts.
2. It is used when there is no condition. And since there is no condition, what does it do here? E.g. If you don't water the plants, they die.
3. The "if" can simply be replaced by "when" or "whenever" in this form only.
4. Its structure is, [If + present simple, present simple] whereas, the conditional, in academic grammar, is put under modal verbs (will, would, should) have to be there.
5. It is used normally to describe facts or to explain how things work. E.g. If you pedal, the bike moves. As the answer is always true, therefore the conditional clause is no conditional at all.
In brief there is no condition in this type because it is not predictive. Compare these examples and see the difference:
If you throw a piece of wood in the sea, it floats. (This is true and it is experimented)
If you drop an egg down, it breaks. (This is true and it is experimented)
Here there is no condition because it is scientifically proven that wood never sinks no matter what the water is, potable or salty.
If you throw this chair in the sea, it will float. (it is probable only)
If you drop this egg down, it will break. (The egg will break on condition you drop it down)
The chair will float only on condition you throw it into the sea, but if you don't the whole conditional is concealed. So the if-clause is the basic of the prediction (the result).
In this case, there is a condition as we can predict the result of the condition. We have to take into consideration that it is probable that the wood in the chair could bear the iron and it is likely that the chair floats. Another thing is also to be taken into consideration, namely the density of salt in the water of the see.
When the situation or action depicted in the if-clause is a result of the main clause, the will future is used in the if-clause.
He'll pay me $10 if I'll help him do the dishes.
(Doing the dishes is the result of paying ten dollars.)

would in if-clauses
In polite requests would is possible in if-clauses.
It would be nice if you would help me in the kitchen.
(Are you ready to help me in the kitchen?)

CONDITIONALS



Definition: The conditional tense says that an action is reliant on something else. The conditionals are used to talk about real or unreal situations, they are sometimes called if-clauses. Real Conditional describes real-life situations. Unreal Conditional describes unreal, imaginary situations.

For example: If a certain condition is true, then a particular result happens.


There are four basic conditionals that we use in English.
  • Zero Conditional
  • First Conditional
  • Second Conditional
  • Third Conditional

    * There are some more conditionals formed by mixing some of these four.
Structure of Conditional Sentences
The Zero Conditional is used for actions that are always true when the conditions are satisfied. The structure of the conditionals is straightforward. There are two basic possibilities in terms of order in the sentence:

IF


Condition


Result


If


it rains,


we will get wet




Result


IF


Condition


we will get wet


If


it rains,



* Notice that we only use a comma in the first example.

Conditionals: Time and Probability Table

Probability


Conditional


Example


Time


Certain


zero conditional


If you heat water to 100 degrees celsius, it boils


any time


Likely


first conditional


If it rains, I will stay in.


future


Unlikely


second conditional


If I won the lottery, I would retire.


future


Impossible


second conditional


If I had the money, I would lend it to you


present


Impossible


third conditional


If I had seen him, I would have given him the message.


past



Zero Conditional: Certainty
The Zero conditional is used for things that are always true as long as the condition is met.

Formation: if + present simple, + present simple

IF


Condition


Result


Situation



present simple


present simple



If


you heat water to 100 degrees celsius,


it boils.


fact- universal



present simple


present simple



If


I drink coffee,


I get a headache.


fact- personal



In these examples, the result will always occur if the condition is met, so the time is not important.

First Conditional: A real possibility in the future
A First Conditional sentence is for future actions dependent on the result of another future action or event, where there is a reasonable possibility of the conditions for the action being satisfied.

Formation: if + present simple, + will

For example: If she gets good grades, she will go to university.

We are talking about the future, but we use a present tense for the condition and will for the result. In this case, the person is sure about going to university. We can use other modal verbs in the result part of the sentence. For example:

IF


Condition


Result


Possibility


If


she gets good grades,


she will go to university.


If the condition is met, then she definitely will go


If


he gets good grades,


he may go to university.


He is not sure about going to university.


If


she gets good grades,


she should go to university.


The speaker is expressing his or her opinion, giving advice.


If


he gets good grades,


he can go to university.


This means that it is possible.


If


she gets good grades,


she could go to university.


This means that it is possible, but not that likely.


If


he gets good grades,


he might go to university.


This means that it is possible, but not that likely.


We can also use different present forms in the condition part of the sentence like: present simple, present progressive, present perfect, etc
Second Conditional: Imaginary Present or Unlikely Future
The Second Conditional can be used used to talk about imaginary present situations, where we are imagining something different from what is really the case. We can also use it to talk about things in the future that are unlikely to happen, as the condition is unlikely to be met. We use the past tense in the condition part and would for the result.
Formation: if + past simple, + would + base form

For Example: If I were you, I'd tell her.

IF


Condition


Time


Result


Possibility



past simple


present


WOULD + base verb


impossible


If


I had the time,



I would learn Italian.


I don't have the time, so I'm not going to learn Italian.



past simple


future


WOULD + base verb


Unlikely


If


I won the lottery



I would travel around the world.


There's a very small chance of winning the lottery, so the trip is unlikely


We can use other modal verbs in the past tense in the result part of the sentence:

IF


Condition


Result


Certainty



past simple


WOULD + base verb



If


I had the time,


I would learn Italian.


Although unlikely to happen, the speaker is sure that they would do it given the opportunity.


If


I had more time,


I might learn English.


Although unlikely to happen, it is only a possibility anyway.


If


I had more time,


I should learn some more about IT.


Although unlikely to happen, the speaker is saying that it would be a good idea, but is not committed to it.


If


I had more time


I could learn Hindi.


Although unlikely to happen, it is only a possibility anyway.


Third Conditional: Imaginary Past The third conditional is used when we are talking about the past and imagining something different from what actually happened, that means for imaginary past actions, where the conditions for the action WERE NOT satisfied.
Formation: if + past perfect, + would have + past participle
For example: If I had known, I would have helped. I didn't know and didn't help.

IF


Condition


Result


Certainty



past perfect


WOULD HAVE+ past participle



If


I had known,


I would have helped.


Although this didn't happen, the speaker is sure about the result.


If


I had known,


I could have helped.


Although this didn't happen, the result is only a possibility.


If


I had known,


I might have helped.


Although this didn't happen, the result is only a possibility.


If


you had known,


you should have helped.


Although this didn't happen, it is only a good suggestion or piece of advice.


Third Second Mixed Conditionals For imaginary present actions or situations that are not possible because the necessary conditions were not met in the past.
Formation: if + past perfect, + would + base form
For example:
  • If you had taken the course, you would know about it. (The conditions were not met because the person did not do the course and as a result does not know about it now.)
Second Third Mixed Conditionals To avoid the illogicality of saying 'If I had been you', which means that I was not you on that occasion, but could be in the future, which is, of course, impossible.
Formation: if + past simple, + would have + past participle
For example:
  • If I were you, I wouldn't have done that.
When the first part is still true
For example:
  • If I could speak English, I wouldn't have needed to get the letter translated. (This means that I couldn't speak English then when I needed the translator and still can't)


Past Conditionals

Past Real Conditional

FORM

[If / When ... Simple Past ..., ... Simple Past ...]
[... Simple Past... if / when ... Simple Past ...]
USE

The Past Real Conditional describes what you used to do in particular real-life situations. It suggests that your habits have changed and you do not usually do these things today.

Examples:
· If I went to a friend's house for dinner, I usually took a bottle of wine or some flowers. I don't do that anymore.
· When I had a day off from work, I often went to the beach. Now, I never get time off.
· If the weather was nice, she often walked to work. Now, she usually drives.
· Jerry always helped me with my homework when he had time. But he doesn't do that anymore.
· A: What did you usually do when it rained?
B: I usually stayed at home.
IMPORTANT Used to

The form "used to" expresses the idea that something was an old habit that stopped in the past. This form is commonly used in Past Real Conditional sentences to emphasize that something was a habit. The examples below have the same meaning as the examples above.
Examples:
· If I went to a friend's house for dinner, I used to take a bottle of wine or some flowers. I don't do that anymore.
· When I had a day off from work, I used to go to the beach. Now, I never get time off.
· If the weather was nice, she used to walk to work. Now, she usually drives.
· Jerry used to help me with my homework when he had time. But he doesn't do that anymore.
· A: What did you usually do when it rained?
B: I used to stay at home.
IMPORTANT If / When

Both "if" and "when" are used in the Past Real Conditional. Using "if" suggests that something happened less frequently. Using "when" suggests that something happened regularly.
Examples:
· When I had a day off from work, I usually went to the beach.
I regularly had days off from work.
· If I had a day off from work, I usually went to the beach.
I rarely had days off from work.
Past Unreal Conditional

FORM

[If ... Past Perfect ..., ... would have + past participle ... ]
[... would have + past participle ... if ... Past Perfect ...]
USE

The Past Unreal Conditional is used to talk about imaginary situations in the past. You can describe what you would have done differently or how something could have happened differently if circumstances had been different.
Examples:
· If I had owned a car, I would have driven to work. But I didn't own one, so I took the bus.
· She would have traveled around the world if she had had more money. But she didn't have much money, so she never traveled.
· I would have read more as a child if I hadn't watched so much TV. Unfortunately, I did watch a lot of TV, so I never read for entertainment.
· Mary would have gotten the job and moved to Japan if she had studied Japanese in school instead of French.
· If Jack had worked harder, he would have earned more money. Unfortunately, he was lazy and he didn't earn much.
· A: What would you have done if you had won the lottery last week?
B: I would have bought a house.

· A: What city would you have chosen if you had decided to move to the United States?
B: I would have chosen Seattle.
IMPORTANT Only use "If"

Only the word "if" is used with the Past Unreal Conditional because you are discussing imaginary situations. "When" cannot be used.
Examples:
· I would have bought that computer when it had been cheaper. Not Correct
· I would have bought that computer if it had been cheaper. Correct
EXCEPTION Conditional with Modal Verbs

There are some special conditional forms for modal verbs in English:
would have + can = could have
would have + shall = should have
would have + may = might have
The words "can," "shall" and "may" cannot be used with "would have." Instead, they must be used in these special forms.
Examples:
· If I had gone to Egypt, I could have learned Arabic.
· If she had had time, she might have gone to the party.
The words "could," should," "might" and "ought to" include Conditional, so you cannot combine them with "would have."
Examples:
· If I had had more time, I could have exercised after work.
· If he had invited you, you might have gone.
Mixed Conditionals

Those of you who have been following the Conditional Tutorial should now be familiar with present, past and future conditional verb forms. Sometimes Unreal Conditional sentences are mixed. This means that the time in the if-clause is not the same as the time in the result. Study the examples below to learn how to mix conditional verb forms like a native speaker.
Verbs in green are in the Present Unreal Conditional.
Verbs in red are in the Past Unreal Conditional.
Verbs in purple are in the Future Unreal Conditional.
Mixed Conditional Patterns


PAST


PRESENT


Examples:
· If I had won the lottery, I would be rich.
But I didn't win the lottery in the past and I am not rich now.
· If I had taken French in high school, I would have more job opportunities.
But I didn't take French in high school and I don't have many job opportunities.
· If she had been born in the United States, she wouldn't need a visa to work here.
But she wasn't born in the United States and she does need a visa now to work here.

PAST


FUTURE


Examples:
· If she had signed up for the ski trip last week, she would be joining us tomorrow.
But she didn't sign up for the ski trip last week and she isn't going to join us tomorrow.
· If Mark had gotten the job instead of Joe, he would be moving to Shanghai.
But Mark didn't get the job and Mark is not going to move to Shanghai.

But Darren wasted his Christmas bonus gambling in Las Vegas and he won't go to Mexico with us next month.

PRESENT


PAST


Examples:
· If I were rich, I would have bought that Ferrari we saw yesterday.
But I am not currently rich and that is why I didn't buy the Ferrari yesterday.
· If Sam spoke Russian, he would have translated the letter for you.
But Sam doesn't speak Russian and that is why he didn't translate the letter.
· If I didn't have to work so much, I would have gone to the party last night.
But I have to work a lot and that is why I didn't go to the party last night.

PRESENT


FUTURE

But my parents are going to come this weekend, and that is why I didn't plan a trip for the two of us to NapaValley.
· If Donna weren't making us a big dinner tonight, I would have suggested that we go to that nice Italian restaurant.
But she is going to make us a big dinner tonight, and that is why I didn't suggest that we go to that nice Italian restaurant.

FUTURE


PRESENT


Examples:
· If I were going to that concert tonight, I would be very excited.
But I am not going to go to that concert tonight and that is why I am not excited.

But Sandy is not going to give a speech tomorrow and that is why she in not nervous.
· If She didn't come with us to the desert, everyone would be very disappointed.
But She will come with us to the desert and that is why everyone is so happy.
Continuous Conditionals

Those of you who have studied Englishpage.com's Verb Tense Tutorial should be familiar with continuous verb tenses such as Present Continuous, Past Continuous, Future Continuous, Present Perfect Continuous, Past Perfect Continuous, and Future Perfect Continuous. The Verb Tense Tutorial gives you all the information you need to create continuous Real Conditional sentences. But many English learners are not aware of the fact that we can use continuousness in imaginary situations as well. Study the examples below to learn how to create continuous Unreal Conditional sentences that will make you sound like a native speaker.
Present Unreal Conditional + Continuous

FORM

If-clause: [were + present participle]
Result: [would be + present participle]
USE

Present Unreal Conditional + Continuous is used to discuss imaginary situations which could be happening at this very moment.
Examples in the if-clause:
· If the sun were shining, I would go to the beach.
Unfortunately, it is raining so I can't go.
· If Sam were sitting here, we would be able to ask him the question ourselves.
But Sam is not sitting here. He is somewhere else.
· We would be able to go sailing if the wind were blowing.
But there is no wind, so we can't go sailing.
Examples in the result:
· If I were in Hawaii, I would be lying on the beach.
But I am not in Hawaii.
· If my grandfather were here, he would be talking about the war.
But he is not here.
· I would be rafting down the Colorado River right now if my leg weren't broken.
But my leg is broken, so I am not there.
Past Unreal Conditional + Continuous

FORM

If-clause: [had been + present participle]
Result: [would have been + present participle]
USE

Past Unreal Conditional + Continuous is used to discuss imaginary situations happening at a very specific time in the past or over a period of time in the past.
Examples in the if-clause:
· If I had been talking to him when he said that, I would have punched him in the face.
But I wasn't talking to him when he said that.
· If he had been standing near the house when the wall collapsed, it would have killed him.
Luckily, he moved away before the wall fell.
Examples in the result:
· If you had gone to his house last night, he would have been sitting on his couch in front of the TV.
But you didn't go to his house, so you didn't see what he was doing.
· If she had missed her train, he would have been waiting for her at the station for hours.
Luckily, she caught her train and he didn't have to wait.
NOTICE that the Past Unreal Conditional + Continuous can be used like the Past Continuous in imaginary situations to emphasize interruptions or parallel actions in the past.
Examples in the if-clause:
· If James had been crossing the street when the car ran the red light, it would have hit him.
· If Tom had been studying while Becky was making dinner, he would have finished his homework early and they could have gone to the movie.
Examples in the result:
· If James hadn't stopped to tie his shoe, he would have been crossing the street when the car ran the red light.
· If you had gone to their house last night, Bob would have been reading the newspaper, Nancy would have been talking on the phone and the kids would have been watching TV. They always do the same things.
NOTICE that Past Unreal Conditional + Continuous can also be used like Present Perfect Continuous or Past Perfect Continuous in imaginary situations to emphasize a duration of time.
Examples in the if-clause:
· Scott said he had been studying Greek for more than five years. If he had been studying the language that long, I think he would have been able to interpret for us at the airport.
· Sarah claimed she had been waiting in the rain for more than twenty minutes by the time we arrived, but she wasn't even wet. If she had been waiting that long, I think she would have been totally drenched by the time we arrived.
Examples in the result:
· Terry's plane arrived ahead of schedule. If I hadn't decided to go to the airport early, she would have been waiting there for more than twenty minutes before I arrived.
· At the travel agency yesterday, I waited for more than an hour for somebody to help me. Finally, I got up and left. If I hadn't decided to leave, I would have been sitting there forever.
Future Unreal Conditional + Continuous

FORM

If-clause: [were + present participle]
Result: [would be + present participle]
USE

Future Unreal Conditional + Continuous can be used like the Future Continuous in imaginary situations to emphasize interruptions or parallel actions in the future.
NOTICE The future form looks the same as the present form. The future is indicated with words such as "tomorrow," "next week" or "in a couple of days."
Examples in the if-clause:
· If I were waiting there next week when he gets off the plane, he would be totally surprised.
But I will not be waiting there, so he won't be surprised.
· If he were staying in that hotel next week while the conference is being held, he might be able to meet some of the key speakers and tell them about our new product.
I don't think he will be able to stay at the hotel, so he won't be able to meet anybody there.
Examples in the result:
· If I were able to go to the train station tonight to meet Sandra, I would be standing on the platform waiting for her when she arrives.
I won't be able to go to the train station, so I will not be standing there when she arrives.
· If you went over to Paul's house after work, he would probably be sitting there at his computer surfing the Internet.
But you won't go over.
Were To

"Were to" in the Present

FORM

[If ... were to + verb ..., ...]
USE

"Were to" can be used in the present to emphasize that the conditional form is extremely unlikely or unthinkably horrible. Notice that this special form is only used in the if-clause.
Examples:
· If she were to be rich, she would be horribly obnoxious.
It is very unlikely that she would be rich.
· If I were to have no friends, who would I spend my time with?
Having no friends is a horrible thought.
· If Nathan were to be my boss, this job would be intolerable.
Nathan's being my boss is a horrible concept.
"Were to" in the Future

FORM

[If ... were to + verb ..., ...]
USE

"Were to" can be used in the future to emphasize that the conditional form is extremely unlikely or unthinkably horrible. Notice that this special form is only used in the if-clause.
Examples:
· If I were to lose my job next year, I would probably not find a new one quickly.
Loosing my job would be terrible.
· If he were to fail his driving test tomorrow, he would have to take it again.
He is not likely to fail his driving test.
· If Sarah were to show up late to the birthday party, it would ruin the surprise.
Sarah will surely come on time.
"Were to" in the Past

FORM

[If ... were to have + past participle ..., ...]
USE

"Were to" can be used in the past to emphasize that the conditional form is extremely unlikely or unthinkably horrible. Notice that this special form is only used in the if-clause.
Examples:
· If the fire were to have destroyed the building, it would have been a tragic cultural loss.
The thought of such a loss is too horrible to consider.
· If the dam were to have burst, the entire town would have been destroyed.
Such destruction is too horrible to consider.
· If Sarah were to have failed the final test, she would have lost her scholarship.
She is an excellent student, and it is very unlikely that she would have failed the test.
Future Conditionals

Future Real Conditional

FORM

[If / When ... Simple Present ..., ... Simple Future ...]
[... Simple Future ... if / when ... Simple Present ...]
Notice that there is no future in the if- or when-clause.
USE

The Future Real Conditional describes what you think you will do in a specific situation in the future. It is different from other Real Conditional forms because, unlike the present or the past, you do not know what will happen in the future. Although this form is called "real", you are usually imagining or guessing about the future. It is called "real" because it is still possible that the action might occur in the future. Carefully study the following examples and compare them to the Future Unreal Conditional examples further down the page.
Examples:
· If I go to my friend's house for dinner tonight, I will take a bottle of wine or some flowers.
I am still not sure if I will go to his house or not.
· When I have a day off from work, I am going to go to the beach.
I have to wait until I have a day off.
· If the weather is nice, she is going to walk to work.
It depends on the weather.
· Jerry will help me with my homework when he has time.
I have to wait until he has time.
· I am going to read if there is nothing on TV.
It depends on the TV schedule.
· A: What are you going to do if it rains?
B: I am going to stay at home.
IMPORTANT If / When

Both "if" and "when" are used in the Future Real Conditional, but the use is different from other Real Conditional forms. In the Future Real Conditional, "if" suggests that you do not know if something will happen or not. "When" suggests that something will definitely happen at some point; we are simply waiting for it to occur. Notice also that the Simple Future is not used in if-clauses or when-clauses.
Examples:
· When you call me, I will give you the address.
You are going to call me later, and at that time, I will give you the address.
· If you call me, I will give you the address.
If you want the address, you can call me.
Future Unreal Conditional

FORM 1 (Most Common Form)

[If ... Simple Past ..., ... would + verb ...]
[... would + verb ... if ... Simple Past ...]
Notice that this form looks the same as Present Unreal Conditional.
USE

The Future Unreal Conditional is used to talk about imaginary situations in the future. It is not as common as the Future Real Conditional because English speakers often leave open the possibility that anything MIGHT happen in the future. It is only used when a speaker needs to emphasize that something is impossible. Because this form looks like Present Unreal Conditional, many native speakers prefer Form 2 described below.
Examples:
· If I had a day off from work next week, I would go to the beach.
I don't have a day off from work.
· I am busy next week. If I had time, I would come to your party.
I can't come.
· Jerry would help me with my homework tomorrow if he didn't have to work.
He does have to work tomorrow.
FORM 2

[If ... were + present participle ..., ... would be + present participle ...]
[... would be + present participle ... if ... were + present participle ...]
USE

Form 2 of the Future Unreal Conditional is also used to talk about imaginary situations in the future. Native speakers often prefer this form over Form 1 to emphasize that the conditional form is in the future rather than the present. Also notice in the examples below that this form can be used in the if-clause, the result, or both parts of the sentence.
Examples:
· If I were going to Fiji next week, I would be taking my scuba diving gear with me. In if-clause and result
I am not going to go to Fiji and I am not going to take my scuba gear with me.
· If I were not visiting my grandmother tomorrow, I would help you study. In if-clause
I am going to visit my grandmother tomorrow.
· I am busy next week. If I had time, I would be coming to your party. In result
I am not going to come to your party.
FORM 3

[If ... were going to + verb ..., ... would be + present participle ...]
[... would be + present participle ... if ... were going to + verb ...]
USE

Form 3 of the Future Unreal Conditional is a variation of Form 2 which is also used to talk about imaginary situations in the future. Notice that this form is only different from Form 2 in the if-clause. Native speakers use Form 3 to emphasize that the conditional form is a plan or prediction in the same way "be going to" is used to indicate a plan or prediction.
Examples:
· If I were going to go to Fiji next week, I would be taking my scuba diving gear with me.
I am not going to go to Fiji and I am not going to take my scuba gear with me.
· If I were not going to visit my grandmother tomorrow, I would help you study.
I am going to visit my grandmother tomorrow.
IMPORTANT Only use "If"

Only the word "if" is used with the Past Unreal Conditional because you are discussing imaginary situations. "When" cannot be used.
Examples:
· I would buy that computer tomorrow when it were cheaper. Not Correct
· I would buy that computer tomorrow if it were cheaper. Correct
EXCEPTION Conditional with Modal Verbs

There are some special conditional forms for modal verbs in English:
would + can = could
would + shall = should
would + may = might
The words "can," "shall" and "may" cannot be used with "would." Instead, they must be used in these special forms.
Examples:
· If I went to Egypt next year, I would can learn Arabic. Unfortunately, that's not possible. Not Correct
· If I went to Egypt next year, I could learn Arabic. Unfortunately, that's not possible. Correct
The words "could," should," "might" and "ought to" include conditional, so you cannot combine them with "would."
Examples:
· If I didn't have to work tonight, I would could go to the fitness center. Not Correct
· If I didn't have to work tonight, I could go to the fitness center. Correct
Future Real Conditional vs. Future Unreal Conditional

To help you understand the difference between the Future Real Conditional and the Future Unreal Conditional, compare the examples below:
Examples:
· If you help me move tomorrow, I will buy you dinner. Future Real Conditional
I don't know if you can help me.
· If you helped me move tomorrow, I would buy you dinner. Future Unreal Conditional
You can't help me, or you don't want to help me.
Conditional Types

The conditional sentence in English can be seen in terms of three principal types.
Type I

We use this type to imply that it is likely that the action in the if-clause will be performed. This kind is structured as follows:

If-clause


main clause


Verb in the present tense


Verb in the future tense


If you work hard,


you will succeed.



It is still probable that you will succeed if the condition (to work hard) is fulfilled.
N.B. The verb in the if-clause is never in the future.

Verb in the present tense


verb in the imperative


If you want to take a photo,

Type II

This type however is used to indicate that the idea is improbable or unreal. The result of the condition is imaginary. It is structured as follows:

If-clause


main clause


Simple past tense (subjunctive)


conditional tense (would do etc.)


If she had wings,


she would fly.


N.B.: It is more a wish than anything probable to occur.
Type III

It is an impossible condition. The structure is as follows:

If-clause


main clause


Past perfect tense


perfect conditional


If + past perfect


should / would have done


If she had been tall enough,


she would have been recruited.


This implies that she was not tall enough that's why she wasn't recruited. It is impossible because the sentence refers to past events that had already finished.
Type Zero

Some scholars add a fourth basic kind which they refer to as "Zero conditional" or "Conditional type Zero", which I cannot recognize as such because its structure can in no way be considered conditional. The conditional, roughly speaking, means the uncertain whereas this type of conditional mostly deals with facts. The reasons if I have to name some are,
1. The result is always a fact. E.g. If you drop sugar into water, it melts.
2. It is used when there is no condition. And since there is no condition, what does it do here? E.g. If you don't water the plants, they die.
3. The "if" can simply be replaced by "when" or "whenever" in this form only.
4. Its structure is, [If + present simple, present simple] whereas, the conditional, in academic grammar, is put under modal verbs (will, would, should) have to be there.
5. It is used normally to describe facts or to explain how things work. E.g. If you pedal, the bike moves. As the answer is always true, therefore the conditional clause is no conditional at all.
In brief there is no condition in this type because it is not predictive. Compare these examples and see the difference:
If you throw a piece of wood in the sea, it floats. (This is true and it is experimented)
If you drop an egg down, it breaks. (This is true and it is experimented)
Here there is no condition because it is scientifically proven that wood never sinks no matter what the water is, potable or salty.
If you throw this chair in the sea, it will float. (it is probable only)
If you drop this egg down, it will break. (The egg will break on condition you drop it down)
The chair will float only on condition you throw it into the sea, but if you don't the whole conditional is concealed. So the if-clause is the basic of the prediction (the result).
In this case, there is a condition as we can predict the result of the condition. We have to take into consideration that it is probable that the wood in the chair could bear the iron and it is likely that the chair floats. Another thing is also to be taken into consideration, namely the density of salt in the water of the see.
When the situation or action depicted in the if-clause is a result of the main clause, the will future is used in the if-clause.
He'll pay me $10 if I'll help him do the dishes.
(Doing the dishes is the result of paying ten dollars.)
would in if-clauses
In polite requests would is possible in if-clauses.
It would be nice if you would help me in the kitchen.
(Are you ready to help me in the kitchen?)
