The correct use of the pronouns, personal and relative, involves a degree of skill which many speakers and writers fail to possess. The choice of the appropriate pronoun, the agreement with its antecedent, the proper case form, are matters that require careful consideration.
Case Forms
Following am, are, is, was, and other forms of the verb to be, the pronoun must be in the nominative case.
“Are you the person that called?” “Yes; I am him.” The answer should have been, “I am he.”
“I saw a man trespassing on my grounds, and I think you are him.” Say, “You are he.”
“It is only me; don’t be afraid.” “It is only I” is the correct form.
“It was him that struck you, not me.” Change him, to he, and me to I.
“It might have been him that sent you the present.” Use he, not him.
“It is him whom you said it was.” The sentence should be, “It is he who you said it was.”
“That was but a picture of him and not him himself.” Say, “and not he himself.”
