First, Second, and Third Person Pronouns

The rule of thumb is this — when you would normally say “I” if you were talking about yourself, you would instead say “my brother and I,” but when you would normally say “me” if you were talking about yourself, you would instead say “my brother and me.”

Are is used for plural subjects, whereas am is used for singular subjects. Jim, John, and I is a plural subject (3 people), so the correct form is “Jim, John, and I are going somewhere.”

For the subject, either “My friends and I” or “I and my friends” is grammatical. The former is preferred because it’s also more polite, placing others first. Your subtext is quite correct: “me” means the object, “I” is the subject.

“This is I” is correct technically. “This is me” is what the vast, vast majority of people actually say in practice. “This is me” is not technically correct, but it is what most people say in reality.

Rule: Use one of the subject pronouns when it is the subject of the sentence. Example: I hit the ball. So “he” and “I” are both the subjects. Sometimes we want to say, “Him and me will . . .” or “Him and I will . . . .” You can remember the correct pronouns by saying each pronoun alone in the sentence.

“He and his wife” is correct. A complete sentence would contain or imply a verb, so you need to use the personal pronoun “he”. e.g. He and his wife went for a walk.

Using “Him” in Sentences. Where there is a “he,” there is a “him.” Much like “he,” “him” is also a third-person masculine pronoun. However, “him” is an object pronoun for the subject pronoun “he.” Sound confusing? Don’t worry, it will get clearer.

The forms he, she and they are used when a pronoun is the subject of a sentence. The forms him, her and them are used when a pronoun is the object of a sentence. The forms his, her, hers, their and theirs are possessive in nature.

“This is she” is grammatically correct. The verb “to be” acts as a linking verb, equating subject and object. So this is she and she is this; “she” and “this” are one and the same, interchangeable, and to be truly interchangeable they must both play the same grammatical role—that of the subject.

Case of a pronoun decides the function of the pronoun in a given sentence. When the pronoun is a subject in the sentence, the subjective case of the pronoun is used. He is the subjective case of the pronoun that is seen when the pronoun performs an action.

Generally speaking, we use this/these to refer to people and things, situations and experiences that are close to the speaker or very close in time. We use that/those to refer to people and things, situations and experiences that are more distant, either in time or physically.
