Indefinite and Partitive Articles (un, une, des, du, de la)

In addition to the definite articles (le, la, l', les), French has indefinite articles and partitive articles. These are used to express "a/an," "some," or an unspecified quantity. Understanding when and how to use each type is essential for constructing accurate French sentences.

Indefinite Articles — Un, Une, Des

The indefinite articles correspond to English "a," "an," and "some" (in the sense of unspecified plural items).

Form	Gender/Number	English	Example
un	Masculine singular	a / an	un livre (a book)
une	Feminine singular	a / an	une maison (a house)
des	All plurals	some / —	des livres (books / some books)

When to Use Indefinite Articles

Use un/une/des when you are talking about non-specific or unidentified items — things that have not been mentioned before or that are not uniquely identified.

Examples:

• J'ai un frère et une sœur. — I have a brother and a sister.
• Il y a un chat dans le jardin. — There is a cat in the garden.
• Elle achète des fleurs. — She is buying (some) flowers.
• C'est une bonne idée. — That's a good idea.
• Je voudrais un café. — I would like a coffee.

Note on des: In English, we often use no article at all for indefinite plurals: "I'm buying flowers." In French, you must use des: J'achète des fleurs. You cannot say J'achète fleurs.

Partitive Articles — Du, De la, De l'

The partitive articles express "some" or "an unspecified amount of" something, particularly with uncountable nouns (things you cannot count individually, like water, bread, money, or music).

Form	Gender	English	Example
du	Masculine singular	some	du pain (some bread)
de la	Feminine singular	some	de la musique (some music)
de l'	Before vowel/silent h	some	de l'eau (some water)

When to Use Partitive Articles

Use partitive articles when you are talking about some of something (an unspecified quantity of an uncountable noun).

Examples:

• Je voudrais du pain. — I would like some bread.
• Tu veux de la confiture ? — Do you want some jam?
• *Il boit **de l'*eau. — He is drinking (some) water.
• Elle mange du fromage. — She is eating (some) cheese.
• Nous écoutons de la musique. — We are listening to (some) music.
• Il faut du courage. — It takes (some) courage.

How Partitive Differs from Indefinite

Article	Used With	Example
un/une	Countable, singular	un pain (a loaf of bread — one whole loaf)
des	Countable, plural	des pains (some loaves)
du/de la/de l'	Uncountable / unspecified amount	du pain (some bread — an unspecified amount)

The distinction is about whether you are counting individual items or referring to a portion of something.

The Negative Rule — De / D'

In negative sentences, all indefinite and partitive articles (un, une, des, du, de la, de l') change to de (or d' before a vowel).
