French personal pronouns

The French personal pronouns (analogous to English I, we, you, and so on) reflect the person and number of their referent, and in the case of the third person, its gender as well (much like English's distinction between him and her, except that French draws this distinction among inanimate nouns as well). They also reflect the role they play in their clause: subject, direct object, indirect object, or other.

The personal pronouns display a number of grammatical particularities and complications not found in their English counterparts: some of them can only be used in certain circumstances; some of them change form depending on surrounding words; and their placement is largely unrelated to the placement of the nouns they replace.

French has a T-V distinction in the second person singular. That is, it uses two different sets of pronouns: tu and vous and their various forms. The pronoun tu is informal and singular, spoken to an individual who is equal or junior to the speaker. The pronoun vous is used in the singular (but with second-person plural verb forms) to speak to an individual who is senior to the speaker or socially "more important" than the speaker. Vous is also used in the plural for all groups of people, whether junior, equal or senior.

As noted above, the personal pronouns change form to reflect the role they play in their clause. The forms used for subjects are called the subject pronouns, subjective pronouns, or nominative pronouns. They are as follows:

When the predicate is être ("to be") plus a noun phrase, the pronoun ce (c' in elision contexts) is normally used instead of the other third person subject pronouns. For example, « C'est un homme intelligent » ("He is a smart man"), « Ce sont mes parents » ("Those are my parents"). Ce is primarily used as a "neuter" pronoun to refer to events and situations: « J'ai vu Jean hier. C'était amusant. », "I saw John yesterday. It was fun."

The subject pronoun (from Old French [h]om, homme "man", from Latin homo "human being") is equivalent to the English indefinite pronouns one, you, and they (as in, "One is pleased to see...", "You never know what will...", and "They speak French in..."). It takes third-person singular verb forms in the same way that il and elle do, and is used:
