thank you
BUT Not until ,Not Since ,Only when
صيغة السؤال تكون فى الجملة الثانية فى اغلب الاحيان

Dear Mr. mahmoudzzz,

Firstly, I've never heard of NOT SINCE

Secondly, there are 2 cases for NOT UNTIL
a) Not until August did the government order an inquiry into the accident.
Here, we use direct inversion because not until is followed by a point in time (August)
b) Not until the train pulled into the station, did Jim find that his coat had gone.
Here, we use the inversion in the second clause.

Best Regards
