When do I use he's and his?

Answer 1

Sometime you use "him and I."but in some cases you need "him and I" together as in "I will pay him money," as you can't use "i will pay he money"

It's either "he and I" or "him and me" or in some cases "He and me" like "he gave the book to me."

In a place where you would say just "he" use "he and I."

For example, you would say "He went to the store" and not "Him went to the store."

So you would use "He and I went to the store."

as the sentence needs the pair of he and I.

In a place where you would just say "him" use "him and me."

For example, you would say "Mary gave a present to him" and not "Mary gave a present to he." So you would say "Mary gave a present to him and me."

as in the above case.

Answer 2

"You and he" is used as the subject of a sentence, e.g., "you and he will go to London tomorrow." "You and him" is used as the object of a sentence or phrase, e.g., "the London group will meet with you and him tomorrow."

Answer 3

I explain via examples:

"He is a good student, and always does his homework."

"I don't like him, he never does his homework"

Answer 4

He's, is a shorter version of "he is" whereas, his means "belonging to him".

Answer 5

"Who is he" is correct. "Who is him" is not correct.
