What's the difference between du and le in French?

Du measures out part of something, le names the whole of it. Je bois du vin means I'm drinking some wine; j'aime le vin means I like wine as a category. Verbs of consumption usually take the partitive, verbs of opinion usually take the definite article.

When do I use des and when do I use les?

Des introduces an unspecified handful — j'ai acheté des pommes, I bought some apples. Les points at all of them or at a set you've both identified — les pommes sont sur la table, the apples are on the table. If you could put some in front of the English noun, you want des.

Why does the article change to de after a negative?

Because un, du, and des are quantity markers, and a negation has already declared the quantity to be zero. Je n'ai pas de temps keeps only the linking de. The definite article escapes this because it identifies something rather than counting it: je n'aime pas le bruit stays as it is.

Is des the plural of un or the plural of du?

Both, and the form is identical either way. Il mange des biscuits could be counting biscuits or taking some of a general supply, and French doesn't distinguish. This is why des behaves like an indefinite article in some rules and like a partitive in others.

How do I remember which article to use?

Run the noun through three questions in order. Do I mean all of it or a known one — le, la, les. Do I mean one countable example — un, une, des. Do I mean an amount of it — du, de la, de l'. Then check whether a negative or a quantity word is nearby, because either one will reduce your answer to de.

French Articles Compared: Le, Un, and Du Side by Side

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

French has three families of article and uses one of them almost everywhere English uses none. Le, la, and les point at a whole category or a known item; un, une, and des count separate units; du, de la, and de l' measure out an unspecified amount. Choosing between them is a question of how much of the noun you mean.

Je bois du café le matin, mais je n'aime pas le café froid.

I drink coffee in the morning, but I don't like cold coffee.

What it is

English can leave a noun bare — I like coffee, I bought coffee — and let context sort out the meaning. French can't. Every common noun arrives with a determiner in front of it, and the one you pick tells your listener whether you mean the category as a whole, one countable example of it, or an unmeasured helping.

J'aime le chocolat, j'ai acheté un chocolat, j'ai mangé du chocolat. — I like chocolate (in general), I bought a chocolate (one unit), I ate some chocolate (an amount).

How to spot it

Ask what quantity you have in mind. All of it, one of them, or some of it. Each answer maps onto one article family.

Les chiens aboient. — Dogs bark. (the whole category)
J'ai vu un chien. — I saw a dog. (one unit)
Il y a du pain sur la table. — There's some bread on the table. (an amount)
Passe-moi le pain. — Pass me the bread. (a known, specific one)

Des is the one form that does double duty: it is both the plural of un and the plural of du, and nothing in the sentence distinguishes the two.

Common Article Comparison Examples in French

The same noun, three different articles, three different meanings:

Definite: Categories and Known Things

Le vin français est réputé.: French wine is famous. (the category)
Elle adore les chats.: She loves cats. (all of them)
Ferme la porte.: Close the door. (the one we both know)
Le lundi, je travaille chez moi.: On Mondays I work from home.

Verbs of liking and hating always take the definite article, because you like the whole category: aimer le café, détester les araignées.

Indefinite: Counting Units

J'ai acheté un livre.: I bought a book.
Il y a une erreur dans le calcul.: There's a mistake in the calculation.
Elle a des amis à Lyon.: She has friends in Lyon.
Prends une pomme.: Take an apple.

Des has no English equivalent, which is why learners drop it. Elle a amis is not a possible French sentence.

Partitive: Some of Something

Je mange du fromage.: I eat cheese / some cheese.
Tu veux de la soupe ?: Do you want some soup ?
Il boit de l'eau.: He drinks water.
Elle fait du sport tous les jours.: She does sport every day.

The partitive is literally de plus the definite article, which is why it looks so much like possession: de + le → du.

The Same Noun, Three Ways

J'aime le gâteau.: I like cake. (in general)
J'ai fait un gâteau.: I made a cake. (one whole one)
J'ai mangé du gâteau.: I ate some cake. (part of one)
Je n'ai pas mangé de gâteau.: I didn't eat any cake. (negated)

Running a noun through all four frames is the fastest way to feel the difference between the systems.

How the Three Systems Divide the Work

The articles are not interchangeable stylistic choices. Each one answers a different question about quantity.

French Nouns Are Rarely Bare

Where English happily says I bought bread, French requires a determiner: j'ai acheté du pain. Leaving the noun alone is the single most common article error, and it makes a sentence sound unfinished rather than merely informal.

Il me faut du temps et de la patience.

I need time and patience.

No bare nouns.

The Definite Article Covers the Whole Category

English uses no article for generalisations; French uses the definite one. Les Français aiment le fromage doesn't mean the French people over there like the cheese — it means French people, as a group, like cheese, as a thing.

Les enfants apprennent vite.

Children learn quickly.

General statement → le, la, les.

The Partitive Is De Plus the Definite Article

Du is de + le, and de la and de l' are unchanged. Knowing this explains the shape of the forms and why the plural of du is des: de + les. It also explains why the partitive collapses back into plain de in the environments where de is all that survives.

Je voudrais du sucre et de la farine.

I'd like some sugar and some flour.

de + le → du, de + les → des.

Countable or Not Decides Un Against Du

If the noun comes in units you can count, use un or une. If it's a mass you can only take some of, use the partitive. Many nouns can go either way depending on what you mean: un café is a cup of coffee, du café is coffee as a substance.

Il a commandé un café et de l'eau.

He ordered a coffee and some water.

One of them → un. Some of it → du.

Negation Flattens Everything to De

After a negative verb, un, une, du, de la, and des all reduce to de or d'. The definite article is the exception: it never reduces, because it identifies rather than counts.

Je n'ai pas d'idée et je ne veux pas de conseils.

I have no idea and I don't want advice.

pas de, whatever the article was.

Common Mistakes with Article Comparison

Incorrect: Je mange pain tous les matins. — I eat bread every morning.

Correct: Je mange du pain tous les matins. — I eat bread every morning.

English can leave a mass noun bare; French can't. An unmeasured amount needs the partitive, so du has to be there.

Incorrect: J'aime le café, alors je bois le café. — I like coffee, so I drink coffee.

Correct: J'aime le café, alors je bois du café. — I like coffee, so I drink coffee.

Aimer takes the whole category, so le is right there. Boire takes an amount, so it switches to the partitive. The same English word covers both.

Incorrect: Je n'ai pas un stylo. — I don't have a pen.

Correct: Je n'ai pas de stylo. — I don't have a pen.

Un reduces to de after a negative. Je n'ai pas un stylo is only correct when you're contradicting a count: not one pen, but two.

Incorrect: Il y a beaucoup des gens ici. — There are a lot of people here.

Correct: Il y a beaucoup de gens ici. — There are a lot of people here.

Quantity expressions take bare de. Beaucoup des gens is only possible when you mean many of the people in a specific group already mentioned.

The Environments Where Articles Collapse into De

Three contexts wipe out the article system and leave a single de behind. Learning them together saves a lot of guesswork.

After a negative

Un, une, du, de la, and des become de or d' when the verb is negated. Le, la, and les are untouched.

Je n'ai pas de voiture.: I don't have a car.
Elle ne mange jamais de viande.: She never eats meat.
Il n'y a plus d'essence.: There's no petrol left.
Je n'aime pas le poisson.: I don't like fish. (definite article survives)

The reason is arithmetical: the negation has already set the quantity to zero, so a quantity word would contradict it.

After an expression of quantity

Beaucoup, peu, trop, assez, plus, moins, and every unit of measurement are followed by bare de.

beaucoup de travail: a lot of work
un kilo de tomates: a kilo of tomatoes
assez d'argent: enough money
une bouteille de vin: a bottle of wine

Two quantity words break the pattern and keep the full article: bien des gens and la plupart des gens both mean most people.

The exceptions that keep their article

Ne… que is a restriction rather than a negation, and a negated être identifies rather than counts, so both leave the article alone.

Je ne bois que de l'eau.: I only drink water.
Ce n'est pas un problème.: That's not a problem.
Ce ne sont pas des touristes.: They're not tourists.
Il n'y a que du pain.: There's only bread.

The test for être is whether the sentence answers what is it rather than how much is there.
