In English, when we talk about a general quantity of something uncountable, we often just say the word: “I drink coffee” or “She has patience.” Sometimes we add “some,” like “I want some bread.”
In French, you cannot leave a noun completely bare. You must always use an article. When you are talking about an unspecified quantity of something—a piece of it, a bit of it, or some of it—you use the partitive article.
The rule
The partitive article is built using the preposition de (of) plus the definite article (le, la, l’, les).
| Gender / Number | Partitive Form | Example |
|---|---|---|
| Masculine singular | du | Je bois du lait. |
| Feminine singular | de la | Elle mange de la viande. |
| Before a vowel | de l’ | Vous buvez **de l’**eau. |
| Plural | des | Ils achètent des pommes. |
Because the partitive is literally saying “of the,” it behaves mechanically like other uses of de and le.
Why it works this way
French relies heavily on articles to signal whether a noun is masculine or feminine, singular or plural. If you just said Je mange pain, the listener loses those structural clues. By forcing a partitive article (literally “I eat of the bread”), French guarantees the noun is introduced smoothly and clearly, preserving the rhythmic structure of the language.
Edge cases
de + le = du and de + les = des are mandatory contractions
You will never see de le or de les in French. When they meet, they instantly contract. De + le becomes du. De + les becomes des. This is not optional slang; it is a strict mechanical rule of the language.
All partitives collapse to de after a negation
When you completely negate a verb, you aren’t talking about “some” quantity anymore; there is exactly zero of it. As a result, the partitive article drops its definite article and collapses down to just de.
- Affirmative: Je bois du lait. (I drink milk.)
- Negative: Je ne bois pas de lait. (I don’t drink milk. Never pas du lait.)
Expressions of quantity take bare de
When you introduce a specific quantity word, you also drop the article and just use de. The quantity word already specifies how much, so you don’t need the partitive “some.”
- beaucoup de temps (a lot of time)
- un peu de café (a little coffee)
- trop de chocolat (too much chocolate)
- un verre de vin (a glass of wine)
English omits ‘some’ freely; French does not
If an English sentence leaves the noun bare, French will still demand the partitive. “I eat bread” must be translated as Je mange du pain. You cannot drop the du.
faire du and jouer de
When talking about sports, French uses faire (to do) + the partitive: Il fait du tennis. When talking about instruments, French uses jouer (to play) + de: Elle joue du piano.
What English speakers get wrong here
- Leaving nouns bare. English speakers constantly try to say things like Je bois café. This sounds completely broken to a French ear. You must say Je bois du café.
- Forgetting to contract. You will be tempted to write de le vin. It must always be du vin.
- Using the partitive after a negation. English speakers will say Je ne mange pas de la viande. It must be Je ne mange pas de viande. When negated, it collapses to de.
