À vs De: Mastering French Prepositions

Vocalyra teaching team · Last updated: October 5, 2026

The prepositions à and de are two of the most common and versatile words in French. Because they have so many different uses, they can be a major source of confusion for learners. This guide will break down their core meanings and show you how to use them correctly in a variety of contexts, from talking about places to constructing complex sentences.

Core Meanings of À and De

At their most basic, 'à' and 'de' point in opposite directions. Think of 'à' as indicating a destination, a point of arrival, or a connection to something. In contrast, 'de' signifies an origin, a point of departure, or a separation from something.

Here are their primary functions:

**À** often translates to 'to', 'at', or 'in'. It indicates: Destination or direction ('Je vais à Paris.' - I'm going to Paris), Location ('Nous sommes à la plage.' - We are at the beach), A specific point in time ('Le film commence à 20h.' - The movie starts at 8 p.m.), Purpose or function ('Une tasse à thé.' - A teacup).

**De** often translates to 'from', 'of', or 'about'. It indicates: Origin ('Il vient de Lyon.' - He comes from Lyon), Possession ('Le livre de Marie.' - Marie's book), Content or material ('Une bouteille d'eau.' - A bottle of water), A topic ('On parle de politique.' - We're talking about politics).

Essential Contractions: Au, Aux, Du, Des

Like English 'do not' becoming 'don't', the prepositions 'à' and 'de' must contract when they appear before the masculine singular article 'le' and the plural article 'les'. This is not optional, it is a mandatory rule of French grammar.

Contractions of à and de with definite articles.
Preposition	Article	Contraction	Example (with English gloss)
à	le	au	Je vais au marché. (I'm going to the market.)
à	les	aux	Elle parle aux enfants. (She is talking to the children.)
de	le	du	C'est le livre du professeur. (It's the professor's book.)
de	les	des	On parle des vacances. (We're talking about the holidays.)

Important: There is no contraction with 'la' or 'l''. You will always say 'à la', 'de la', 'à l'', and 'de l''. For example: 'Je vais à la piscine.' (I'm going to the pool.) or 'Le début de l'histoire.' (The beginning of the story.)

Talking About Places: Cities and Countries

Choosing the correct preposition for geographical locations depends on the gender and number of the country and whether you are talking about going 'to' a place ('à' family) or coming 'from' a place ('de' family).

For destinations (going to, living in):

**à + city**: J'habite à Paris. (I live in Paris.)
**en + feminine country or continent**: Nous allons en France, en Asie. (We are going to France, to Asia.)
**au + masculine country**: Il travaille au Canada. (He works in Canada.)
**aux + plural country**: Ils voyagent aux États-Unis. (They are traveling to the United States.)

For origins (coming from):

**de / d' + city or feminine country**: Je viens de Rome. (I come from Rome.) Elle revient de Belgique. (She is coming back from Belgium.)
**du + masculine country**: Tu viens du Portugal. (You come from Portugal.)
**des + plural country**: Ils sont revenus des Pays-Bas. (They came back from the Netherlands.)

Nouns with À vs De: Purpose vs. Content

The choice between 'à' and 'de' after a noun can completely change its meaning. A simple rule is that 'à' often describes the purpose or function of an object, while 'de' describes its content, material, or what it is about.

**une tasse à café** (a coffee cup) is a cup designed *for* coffee. The cup is empty.
**une tasse de café** (a cup of coffee) is a cup that is filled *with* coffee.
**un verre à vin** (a wine glass) is the specific type of glass used *for* wine.
**un verre de vin** (a glass of wine) is a glass containing wine.
**un sac à dos** (a backpack) is a bag carried *on* the back (its function).
**un livre d'histoire** (a history book) is a book *about* history (its content).
**une robe de soie** (a silk dress) is a dress made *of* silk (its material).

Verbs followed by À + Infinitive

Many French verbs must be followed by the preposition 'à' before another verb in the infinitive form. This is a grammatical structure you need to memorize. Common examples include:

**apprendre à**: J'apprends à conduire. (I am learning to drive.)
**commencer à**: Il a commencé à pleuvoir. (It started to rain.)
**aider (quelqu'un) à**: Je t'aide à faire tes devoirs. (I'm helping you to do your homework.)
**réussir à**: Elle a réussi à obtenir le poste. (She succeeded in getting the job.)
**hésiter à**: N'hésitez pas à poser des questions. (Don't hesitate to ask questions.)

Verbs followed by De + Infinitive

Similarly, another large group of verbs requires 'de' before an infinitive. These verb constructions are fixed and are a key part of sounding natural in French.

**arrêter de**: Arrête de faire ce bruit ! (Stop making that noise!)
**décider de**: Nous avons décidé de déménager. (We decided to move.)
**essayer de**: J'essaie de comprendre la leçon. (I am trying to understand the lesson.)
**oublier de**: J'ai oublié d'acheter du pain. (I forgot to buy bread.)
**finir de**: As-tu fini de manger ? (Have you finished eating?)

Adjectives with À and De

The choice between 'à' and 'de' after an adjective also follows specific patterns. The structure 'Il est + adjective + de' is very common for making general statements.

**Adjective + de + infinitive** often expresses a personal feeling or judgment about an action: 'Je suis content de te voir.' (I am happy to see you.)
**Adjective + à + infinitive** describes the quality of a specific noun: 'Ce livre est difficile à lire.' (This book is difficult to read.)
**Impersonal 'Il est + adjective + de + infinitive'** makes a general statement: 'Il est important de bien dormir.' (It is important to sleep well.)

Compare these two sentences: 'Ce problème est facile à résoudre.' (This specific problem is easy to solve.) versus 'Il est facile de critiquer.' (It is easy to criticize, a general truth).

Common Mistakes to Avoid

Navigating 'à' and 'de' takes practice. Here are some of the most frequent errors learners make:

**Confusing purpose and content:** Asking for 'une tasse à café' when you want a drink. Remember: you drink 'une tasse de café'.
**Forgetting contractions:** Saying 'Je vais à le cinéma' instead of the correct 'Je vais au cinéma'. Contractions are mandatory.
**Using the wrong verb preposition:** Saying 'J'essaie à parler français'. The verb 'essayer' always takes 'de': 'J'essaie de parler français'.
**Mixing up prepositions for places:** Saying 'J'habite en Canada'. Masculine countries like Canada use 'au': 'J'habite au Canada'.
