Indefinite articles – un, une, des

'A', 'an', and 'some'

The indefinite article means a / an, and in the plural some. Like le/la, it agrees with the noun.

The forms

singularplural
masculineun chatdes chats
feminineune maisondes maisons
  • J'ai un chien et une tortue.I have a dog and a tortoise.
  • Il y a des enfants dans le parc.There are (some) children in the park.

Des: the plural of un/une

English often uses no article at all in the plural, but French needs des:

  • J'ai des amis à Paris.I have friends in Paris.
  • Elle mange des fraises.She's eating strawberries.

Before a vowel, the s of des links with a z: des‿amis.

Un, une are also "one"

Un/une is also the number one: un café et deux croissants.

When they change

For uncountable things (some bread, some water), French uses du, de la: see Partitive articles.
