Indefinite Articles For Intermediate learners
What Are Indefinite Articles (Les articles indéfinis) in French?
In French, indefinite articles (les articles indéfinis) are used to refer to unspecified objects or people, or to introduce something for the first time. They are equivalent to "a," "an," or "some" in English.
Unlike definite articles (le, la, l', les), which point to something specific, indefinite articles are used when the noun is not known to the listener or is general/unspecified.
Forms of Indefinite Articles
French indefinite articles change depending on gender (masculine or feminine) and number (singular or plural). Here's a table of indefinite articles:
Article | Gender | Number | English |
|---|---|---|---|
un | masculine | singular | a / an |
une | feminine | singular | a / an |
des | masculine or feminine | plural | some or no article |
un livre
a book
une table
a table
des amis
some friends
"des" is always plural and does not indicate gender.
When To Use Indefinite Articles
Indefinite articles (un, une, des) are used to talk about non-specific or newly introduced nouns whose identity or quantity is not precisely defined.
1. Introducing Something or Someone for The First Time
Use an indefinite article when a noun is mentioned for the first time.
J'ai vu un chien dans la rue.
I saw a dog in the street.
Hier, j'ai rencontré un homme intéressant.
Yesterday, I met an interesting man.
Elle a acheté une robe.
She bought a dress.
Il y a des enfants dans le jardin.
There are some children in the garden.
Tip!
Once the noun is known, French switches to the definite article:
J'ai rencontré une fille. La fille s'appelle Marie.
I met a girl. The girl is called Marie.
2. Talking About One Example Among Many
Use an indefinite article to refer to one element of a group.
C'est un problème important.
It's an important problem.
Elle cherche une solution.
She is looking for a solution.
3. Expressing an Unspecified Quantity (plural)
Des is used when the number is unknown or unimportant.
J'ai acheté des pommes.
I bought some apples.
Il a des idées intéressantes.
He has interesting ideas.
Professions after être (to be)
When talking about professions after être, the use of an article depends on whether the noun is qualified or not.
No article if the noun is unqualified: When the noun simply labels someone and has no adjectives or extra description, do not use un / une / des.
Il est médecin.
He is a doctor.
Il est ingénieur.
He is an engineer.
Article required if the noun is qualified: When the noun is modified by an adjective, a complement, or a relative clause, the indefinite article is mandatory.
Il est un bon professeur.
He is a good teacher.
Elle est une médecin très compétente.
She is a very competent doctor.
Article required after C'est / Ce sont: After c'est / ce sont, professions and roles require an indefinite article.
C'est un médecin.
He/She is a doctor.
Ce sont des ingénieurs.
They are engineers.
Tip!
When a plural noun has an adjective before it, des often changes to de. For example:
J'ai acheté de belles fleurs.
I bought beautiful flowers.
Nous avons vu de vieux bâtiments.
We saw old buildings.
In negative sentences, des → de for plural countable nouns:
J'ai des amis → Je n'ai pas de amis.
I have friends → I don't have any friends.
Un / une do not change in negative sentences:
J'ai un chien → Je n'ai pas un chien.
I have a dog → I don't have a dog.
Countable vs. Uncountable Nouns
Indefinite articles are only used with countable nouns—things you can count individually (books, apples, chairs, people, clothes, etc.).
un livre
a book
une pomme
an apple
des stylos
some pens
Uncountable nouns (things you cannot count individually) do not use un / une / des. For these, French uses partitive articles (du, de la, de l').
Je bois de l'eau.
I drink water.
J'achète du sucre.
I buy sugar.
Elle a de la patience.
She has patience.
