جزاكم الله خيرا مستر ممدوح انا طبعا متأكد فى الامتحان مش ممكن حاجه زى دى تيجى لان الموضوع خلافى والاراء قيه منوعه ولكننا نتناقش للمعرفه وهذا راى اخر لمدرس بريطانى عندما ارفقت رد موقع Disputed English
Grammar
Hello Essam,
There is no right answer to your question: the usage is disputed, as your article suggests.
However, it is only a disputed usage to the very small number of native speakers who trouble themselves about such things. The greater number of the remainder would say "it's me".
Furthermore, although native speakers sometimes say "it is I", "It's I" is very unusual. After "It's", you would usually find "me".
Best wishes,
MrP
