Personal pronouns in French
French personal pronouns (analogous to English I, you, he/she, we, they, etc.) reflect the person and number of their referent, and in the case of the third person, its gender as well (much like the English distinction between him and her, except that French lacks an inanimate third person pronoun it or a gender neutral they and thus draws this distinction among all third person nouns, singular and plural). They also reflect the role they play in their clause: subject, direct object, indirect object, or other.
