Introduction
If there are two French words that cause endless confusion for learners, they are de and à. These tiny prepositions appear constantly — in virtually every sentence — and they carry multiple different meanings depending on context.
In English, we'd use a whole range of different prepositions to cover the meanings of de and à: "of," "from," "about," "with," "in," "to," "at," "for," and more. In French, much of this territory is covered by just these two words.
This guide breaks down the main uses of de and à clearly, with plenty of examples, so you can use them with confidence rather than guessing.
Part 1: The Preposition DE
De is one of the most common words in French. In its various uses, it corresponds to English "of," "from," "about," "with," or sometimes nothing at all.
Use 1: Possession and Relationship (Of)
De is used to express possession and relationships between nouns — where English uses 's or "of":
- le livre de Marie — Marie's book (the book of Marie)
- la porte de la maison — the door of the house
- la capitale de la France — the capital of France
- un ami de mon frère — a friend of my brother
Note that French expresses possession differently from English. There is no 's in French — always use de:
- ❌ Marie's livre (does not exist in French)
- ✅ le livre de Marie
Use 2: Origin (From)
De indicates where someone or something comes from:
- Je viens de Paris. — I come from Paris.
- Il est de Lyon. — He's from Lyon.
- Cette recette vient du Maroc. — This recipe comes from Morocco.
- Un vin de Bourgogne — A wine from Burgundy
Use 3: Partitive and Quantity (Some / Of)
De combines with the definite article to form partitive articles (du, de la, de l', des), expressing an unspecified quantity:
- Je mange du pain. — I eat (some) bread.
- Elle boit de la limonade. — She drinks (some) lemonade.
- Il a des amis. — He has (some) friends.
- Vous voulez de l'eau? — Do you want (some) water?
After a negative, the partitive article becomes simply de (or d'):
- Je ne mange pas de pain. — I don't eat bread. (no partitive after negative)
- Il n'a pas d'amis. — He has no friends.
After expressions of quantity, also use de alone:
- un verre de vin — a glass of wine
- une tasse de café — a cup of coffee
- beaucoup de travail — a lot of work
- trop de sucre — too much sugar
- peu de temps — little time
- assez de place — enough room
Use 4: Content or Subject Matter (About / Of)
De indicates what something is about or what it contains:
- un livre de cuisine — a cookery book (a book of cooking)
- un cours de français — a French class (a class of French)
- parler de quelque chose — to talk about something
- se souvenir de — to remember (to remember of)
- avoir besoin de — to need (to have need of)
Use 5: Material or Composition (Of / Made Of)
- une table en bois / de bois — a wooden table (a table of wood)
- une robe de soie — a silk dress
- une montre en or — a gold watch
Use 6: Time and Manner
- de nuit — at night / by night
- de jour — during the day
- d'habitude — usually
- de temps en temps — from time to time
- tout de suite — immediately
Use 7: After Many Verbs (Verbal DE)
Dozens of French verbs require de before an infinitive. This must be memorised for each verb. Common examples:
| Verb | Meaning | Example |
|---|---|---|
| essayer de | to try to | J'essaie de comprendre. |
| décider de | to decide to | Elle a décidé de partir. |
| oublier de | to forget to | N'oublie pas de rappeler. |

| avoir envie de | to feel like | J'ai envie de sortir. |
| être content de | to be happy to/about | Je suis content de te voir. |
| remercier de | to thank for | Je te remercie de ton aide. |
Contractions with DE
When de is followed by a masculine singular definite article le or a plural les, they contract:
- de + le = du: Je parle du professeur. (I'm talking about the teacher.)
- de + les = des: Je parle des professeurs. (I'm talking about the teachers.)
But de + la and de + l' do not contract:
- Je parle de la directrice. (I'm talking about the director.)
- Je parle de l'élève. (I'm talking about the student.)
Part 2: The Preposition À
À corresponds to a range of English prepositions: "at," "to," "in," "by," "for," "with," and more.

À indicates where something or someone is located:

Contractions with À
When à precedes le or les, they contract:
- à + le = au: Je vais au marché. (I'm going to the market.)
- à + les = aux: Je parle aux étudiants. (I'm speaking to the students.)
But à + la and à + l' do NOT contract:
- Je vais à la boulangerie. (I'm going to the bakery.)
- Je vais à l'école. (I'm going to school.)
DE vs À: Common Confusions
1. Penser à vs penser de
- penser à = to think about (in one's thoughts, to have on one's mind): Je pense à toi. (I'm thinking of you.)
- penser de = to think about (to have an opinion on): Qu'est-ce que tu penses de ce film? (What do you think of this film?)

- à l'hôpital = at the hospital (general: as a patient or visitor)
- dans l'hôpital = in the hospital (physically inside the building)
3. De vs. du / de la / des
Remember that after negation, the partitive article (du, de la, des) always becomes de:
- J'ai du café. (I have coffee.) → Je n'ai pas de café. (I have no coffee.)
- Il mange des pâtes. (He eats pasta.) → Il ne mange pas de pâtes. (He doesn't eat pasta.)
4. Jouer à / jouer de

Tips for Mastering DE and À
1. Learn verbs with their preposition
When you learn a new verb, always note whether it takes à, de, or neither before an infinitive. Create Anki cards: front = verb, back = verb + preposition + example sentence.
2. Memorise the contractions
au and aux (for à) and du and des (for de) are so common that they need to become automatic. Write example sentences for each.
3. Read a lot
The only way to develop a genuine instinct for de and à is massive exposure. You'll start to feel when each one is right through reading, even without being able to articulate the rule.
4. Practise with food vocabulary
French food vocabulary is excellent practice for à (describing flavours: tarte aux pommes, glace au chocolat) and de (describing types: verre de vin, tasse de thé, cours de cuisine).
Conclusion
De and à are the workhorses of French prepositions. They can't be mapped neatly onto English equivalents because they each carry multiple meanings that overlap with many English prepositions.
The best approach is to learn them in context — through example sentences, reading, and listening — rather than trying to memorise abstract rules. Over time, the right choice becomes instinctive, and you'll find yourself reaching for au and du naturally without stopping to think.
They're small words with enormous importance. Master de and à and a huge portion of French grammar becomes cleaner.
