French grammar is the set of rules by which the French language creates statements, questions and commands. In many respects, it is quite similar to that of the other Romance languages.

French is a moderately inflected language. Nouns and most pronouns are inflected for number (singular or plural, though in most nouns the plural is pronounced the same as the singular even if spelled differently); adjectives, for number and gender (masculine or feminine) of their nouns; personal pronouns and a few other pronouns, for person, number, gender, and case; and verbs, for tense, aspect, mood, and the person and number of their subjects. Case is primarily marked using word order and prepositions, while certain verb features are marked using auxiliary verbs.
