spot the error

av abhishiekIt was him who came running into the classroom.

Although there really is no error, the examiner probably thinks that he should replace him. Using he would not be wrong, but most native speakers would use the objective case.

av abhishiekPlease enlighten me about usage of him & I in a sentence

Aspara GusUse I, he, she, and we when the pronoun functions as subject, and use me, him, her, and us when the pronoun functions as subject complement or the object of a verb or preposition.

It would be really easy if you can explain using some sentences,I would appreciate it very much

The best way to determine the right pronoun case is to identify the function of the pronoun. If the pronoun is functioning as the subject of a clause, then use a subject pronoun, I, he, she, or we.

I am hungry.

thanks,that was very helpful

@Aspara My father/ is very quicker than /I at chess/NE - in this sentence shouldnt "me" be used instead of I

av abhishiekin this sentence, shouldn’t "me" be used instead of "I"?

Yes. Using just I sounds too stuffy. Use either than me or than I am.

The very quicker part is wrong, by the way.
