French grammar

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.

Verbs in French are conjugated to reflect the following information:

Some of these features are combined into seven tense–aspect–mood combinations. The simple (one-word) forms are commonly referred to as the present, the simple past or preterite (past tense, perfective aspect), the imperfect (past tense, imperfective aspect), the future, the conditional, the present subjunctive, and the imperfect subjunctive. However, the simple past is rarely used in informal French, and the imperfect subjunctive is rarely used in modern French.

Verbs in the finite moods (indicative, imperative, subjunctive, and conditional) are also conjugated to agree with their subjects in person (first, second, or third) and number (singular or plural). As in English, the subject must be included (except in the imperative mood); in other words, unlike other Romance languages, French is neither a null-subject nor a pro-drop language.

Auxiliary verbs are combined with past participles of main verbs to produce compound tenses, including the compound past (passé composé). For most main verbs the auxiliary is (the appropriate form of) avoir ("to have"), but for reflexive verbs and certain intransitive verbs the auxiliary is a form of être ("to be"). The participle agrees with the subject when the auxiliary is être, and with a preceding direct object (if any) when the auxiliary is avoir. Forms of être are also used with the past participles of transitive verbs to form the passive voice.

The imperative mood, which only has first-person plural and second-person singular and plural forms, usually has forms similar or identical to the corresponding ones in the present indicative.

The pronoun varies in gender (masculine or feminine), in number (singular or plural), and sometimes also in person. It always takes on the meaning of the word or group of words it replaces (the reference). This function is expressed by its name: pro-noun meaning that which is “for,” “put in the place of” a noun. Its meaning also depends on the extralinguistic context (when the pronoun is a deictic), or on the textual context (depending on whether the pronoun is an anaphoric or a cataphoric one). The meaning of the cataphoric pronoun “this one,” on the other hand, depends either on the context or on the word to which it refers. The syntactic characteristics of the pronoun are identical to those of the noun, which the pronoun can replace in the sentence.
