What is the difference between les and des in French?

Les means the, or refers to a whole category: les voisins sont sympas, the neighbours are nice, and les chats dorment beaucoup, cats sleep a lot. Des means some or an unspecified number: il y a des chats dans le jardin, there are cats in the garden.

Why does French say j'aime les livres when English says I like books?

Because French marks generalisations with the definite article. Without les, the sentence has no article at all, which French does not allow. J'aime les livres covers books as a whole; j'aime des livres would suggest a few particular ones and sounds odd.

Why is it de bonnes idées and not des bonnes idées?

When an adjective stands between the article and the plural noun, standard French drops the s from des. So des idées becomes de bonnes idées, and des amis becomes de vieux amis. Put the adjective after the noun and des returns: des idées originales.

Is des ever the same as of the?

Yes, and it is a genuinely different word that happens to be spelled the same. De plus les contracts to des, so les photos des vacances means the holiday photos. Context is the only way to tell it apart from the indefinite des.

How do I remember when des becomes de?

Three triggers remove the s: a negative (pas de bagages), a preceding adjective (de grands bagages), and a quantity word (beaucoup de bagages). If none of those is present, des stays intact.

Les and Des in French: Choosing the Right Plural Article

Written by Camille Laurent, Lead French Curriculum Editor · Reviewed May 2026

Les is the plural of le, la, and l', and it points at a specific group or at a whole category. Des is the plural of un, une, du, and de la, and it introduces an unspecified number of things. French needs one of them in front of almost every plural noun, even where English uses no article at all.

J'ai acheté des pommes, mais les pommes du marché sont meilleures.

I bought some apples, but the apples from the market are better.

What it is

English lets a plural noun stand on its own. I like dogs and I bought apples both work with nothing in front of the noun. French almost never allows that, so every plural noun needs either les for a group you can identify or a category as a whole, or des for a number of things you are not counting.

J'aime les chiens, et j'ai des chiens. — I like dogs, and I have dogs.

How to spot it

Ask whether you could put the in front of the English. If you could, use les. If the natural English is some or nothing at all, use des.

Les enfants sont rentrés. — The children have come home. (a known group)
Les enfants apprennent vite. — Children learn quickly. (the whole category)
Il y a des enfants dans le jardin. — There are children in the garden. (an unspecified number)
Je n'ai pas d'enfants. — I don't have children. (des reduces to de)

Les never changes shape for gender, so les hommes and les femmes look identical apart from the noun.

Common Les and Des: The Plural Articles Examples in French

The two plural articles at work:

Les for a Group You Can Point At

Les valises sont dans le coffre.: The suitcases are in the boot.
Ferme les fenêtres, s'il te plaît.: Close the windows, please.
Où sont les autres ?: Where are the others?
Les invités arrivent à huit heures.: The guests are arriving at eight.

This is the straightforward use: both you and your listener know which ones you mean.

Les for a Whole Category

J'aime les chiens.: I like dogs.
Les Français boivent beaucoup de café.: French people drink a lot of coffee.
Les maths ne sont pas mon point fort.: Maths isn't my strong point.
Elle déteste les araignées.: She hates spiders.

English drops the article for generalisations and French keeps it, which makes this the single biggest source of missing articles.

Des for an Unspecified Number

J'ai des questions.: I have some questions.
Il y a des nuages à l'horizon.: There are clouds on the horizon.
Elle a acheté des fleurs.: She bought flowers.
Ce sont des amis à moi.: They're friends of mine.

Des often has no English equivalent at all, which is why it is so easy to leave out.

When Des Shrinks to De

Je n'ai pas de frères.: I don't have any brothers.
Ce sont de vieux amis.: They're old friends.
Il a de bonnes idées.: He has good ideas.
beaucoup de gens: a lot of people

Three triggers pull des down to de: a negative, an adjective placed before the noun, and a word of quantity.

How the Plural Articles Work

French treats an article as part of the noun rather than as an optional extra, and that one habit explains most of the differences from English.

A Plural Noun Is Rarely Left Bare

English can say I bought apples. French cannot say j'ai acheté pommes. Something has to occupy the article slot, and for an uncounted plural that something is des.

J'ai acheté des pommes et des poires.

I bought apples and pears.

No bare plurals.

Les Does Double Duty

Les translates both the books on this table and books in general. English uses the for the first and nothing for the second, so English speakers under-use les in exactly the sentences where French needs it most.

Les livres coûtent cher en France.

Books are expensive in France.

Category or known group, both take les.

Des Is Two Different Words

One des is the plural indefinite article, meaning some. The other is de plus les squeezed together, meaning of the. They look identical, and only the sentence tells you which is which: des enfants jouent, the children are unspecified; les jouets des enfants, the toys belong to specific children.

Les jouets des enfants sont partout.

The children's toys are everywhere.

some things, or of the things.

A Preceding Adjective Cuts Des Back to De

When an adjective sits in front of the plural noun, standard French reduces des to de. Des amis becomes de vieux amis, des idées becomes de bonnes idées. The rule does not apply when the adjective follows the noun.

Elle m'a raconté de belles histoires.

She told me some lovely stories.

de + adjective + plural noun.

Negation Erases Des Entirely

After ne… pas, ne… plus, or ne… jamais, the indefinite des collapses to de. The definite les is untouched, which gives the useful pair je n'ai pas de livres against je n'aime pas les livres.

Il n'y a plus de places libres.

There are no free seats left.

pas de, but pas les.

Common Mistakes with Les and Des: The Plural Articles

Incorrect: J'ai amis à Paris. — I have friends in Paris.

Correct: J'ai des amis à Paris. — I have friends in Paris.

English has no plural indefinite article, so there is nothing to translate and the slot gets left empty. French requires des before an uncounted plural.

Incorrect: J'aime chiens. — I like dogs.

Correct: J'aime les chiens. — I like dogs.

For a general statement about a whole category, French uses the definite article. Aimer, adorer, détester, and préférer nearly always take les with a plural noun.

Incorrect: Je n'ai pas des enfants. — I don't have children.

Correct: Je n'ai pas d'enfants. — I don't have children.

Des cannot survive a negative. It becomes de, and then elides to d' before the vowel of enfants.

Incorrect: Ce sont des bons vins. — They're good wines.

Correct: Ce sont de bons vins. — They're good wines.

Bon comes before the noun, and a preceding adjective reduces des to de. With a following adjective des is correct: ce sont des vins français.

The Three Places Des Disappears

Des is the least stable article in French. Learning what removes it is more useful than learning long lists of examples.

Before an adjective that precedes the noun

Standard written French uses de rather than des when an adjective comes before the plural noun.

de bonnes nouvelles: good news
de petits problèmes: small problems
de jeunes musiciens: young musicians
de nombreux exemples: numerous examples

Fixed compounds behave as single nouns and keep des: des petits pois, peas, and des jeunes filles, girls.

After a negative

Ne… pas, ne… plus, and ne… jamais turn des into de, because the quantity being described is zero.

Je n'ai pas d'amis ici.: I don't have any friends here.
Il n'y a pas de solutions faciles.: There are no easy solutions.
Elle ne fait jamais de fautes.: She never makes mistakes.

After être the article stays: ce ne sont pas des amis, they aren't friends. Être identifies rather than quantifies.

After a word of quantity

Any adverb, container, or number word already gives the amount, so des reduces to plain de.

beaucoup de touristes: a lot of tourists
trop de bagages: too much luggage
une dizaine de personnes: about ten people

La plupart is the exception that keeps its article: la plupart des touristes.
