Partitif ou défini ? du café / le café

Unité GR-05 · campagne 4 · la tasse ou la catégorie.

What the forms mean

Du café and le café are both grammatical — the error is picking the wrong one for the sentence you are in. The distinction is between a portion and a category:

• Partitive (du, de la, de l') — an unmeasured amount that gets consumed: je bois du café, tu veux **de l'**eau ?, les Français mangent du pain à presque tous les repas.
• Definite (le, la, les) — the thing as a whole category, judged or preferred: j'adore le café, elle déteste le bruit.

This is one of two contrasts that carry most of the determiner system — counted or measured and new or known — both laid out, with un café / le café / du café side by side, on Qu'est-ce qu'un déterminant ? Le sens de chaque famille.

The verb test

Because meaning is slippery mid-sentence, lean on the verb — it almost always decides for you:

1. Consumption verbs — boire, manger, prendre, acheter — take the partitive. You consume a portion, never the world's supply.
2. Preference verbs — aimer, adorer, détester, préférer — take the definite. A preference is a verdict on the whole category.

This unit also closes the loop with GR-01 and GR-03: under negation the partitive reduces (je ne bois pas de café) while the preference frame keeps its definite (je n'aime pas le café). One verb check now settles both the affirmative and the negative sentence. The items below drill the verb test until it fires before you write the article.

Going further

Minimal pairs. One change between the two sentences, and what it does:

The errors to watch.

From Russian and English. Russian has a partitive of its own, the genitive of part: выпить чаю, налей воды — some of it — against я люблю чай, the whole. That contrast is du thé against le thé. But in Russian the choice is often optional (and the special form чаю is fading); in French the partitive is compulsory whenever an unspecified amount of a mass noun is meant. English gives no help: I drink tea and I like tea use the same bare noun. Where English could add some, French needs du.

The complete rule. The verb test decides most sentences; three cases finish the rule. A consumption verb takes the definite when the noun is specified: je bois le café que tu as fait. A generic subject takes the definite: le café coûte cher. And a set of fixed frames keeps the partitive with qualities and activities: avoir du courage, de la patience; faire du sport. Jouer du piano only looks like one: it is jouer de + le piano, so it stays du under negation (je ne joue pas du piano), where faire du sport reduces (je ne fais pas de sport).

Counted or measured, new or known — the two contrasts behind this unit — are on Qu'est-ce qu'un déterminant ? Le sens de chaque famille.
