Number | Le nombre

In French, all nouns are either singular or plural. When a noun refers to more than one person, place, thing, idea, or quality, it must be made plural.

Note: Throughout this site, an ‘s.’ is used to designate the singular form of words and a ‘p.’ is used to designate the plural form of words.

 

le singulier (s.) ou le pluriel (p.) | singular or plural

 

The number of a word (singular or plural) can relate to five parts of speech: the nouns, the determiners/articles, the adjectives, the pronouns and the verbs.

 

For example | Par exemple:

determiners/articles:

  • ma pomme – mes pommes | my apples
    cette pomme – ces pommes | these/those apples
    la pomme – les pommes | the apples
    When a noun changes to the plural, its respective determiner/article must also change to the plural form.

 

adjectives:

  • la pomme rouge – les pommes rouges | the red apples
    When a noun changes to the plural, its respective adjective must also change to the plural form.

 

pronouns:

  • Elle (la pomme rouge) est juteuse. – Elles (les pommes rouges) sont juteuses. | They (the red apples) are juicy.
    The pronouns must agree in number with the nouns or the noun phrases they substitute.

 

verbs:

  • La pomme tombe dans le panier. – Les pommes tombent dans les paniers. | The apples fall into the baskets.
    The conjugated verb must also agree in number with its subject.
