• Pronoun Case

Pronouns (and nouns) in English display "case" according to their function in the sentence. Their function can be:

• subjective (they act as the subject)
• objective (they act as the object)
• possessive (they show possession of something else)

The following table shows the different forms for pronouns depending on case.

			subjective case	objective case	possessive case
personal pronouns	singular	1st	I	me	mine
		2nd	you	you	yours
		3rd	he she it	him her it	his hers its
	plural	1st	we	us	ours
		2nd	you	you	yours
		3rd	they	them	theirs
relative / interrogative pronouns			who	whom	whose
			whoever	whomever
			which, that, what	which, that, what
indefinite pronouns			everybody	everybody	everybody's

A problem of case:

Mary and I or Mary and me?

1. Mary and I are happy to be here today. (NOT Mary and me)
2. Ati sent the letter to Mary and me. (NOT Mary and I)

In 1, Mary and I are subjects, which is why the pronoun takes the subjective case ("I"). In 2, Mary and I are objects, which is why the pronoun takes the objective case ("me"). An easy way to check the correct case is to try the sentence without Mary. Would you say "I am happy to be here" or "Me am happy to be here"? Would you say "Ati sent the letter to me" or "Ati sent the letter to I"?
