The Ultimate Guide to French Prepositions: 'À' vs. 'De'

The Preposition Battlefield

For English speakers, French prepositions can feel like a guessing game. In English, we have "at," "to," "in," "from," and "of." In French, most of these concepts are squeezed into just two tiny words: à and de. The secret to mastering them is to stop translating word-for-word and start understanding the direction and relationship they imply.

The General Rule: Destination vs. Origin

At their most basic level, these two prepositions represent opposite directions.

• À (To / At / In): Represents a destination, a location, or a point in time. It points towards something.
  Je vais à la plage. (I am going to the beach.)
• De (From / Of): Represents an origin, a starting point, or possession. It points away from something or shows belonging.
  Je viens de la plage. (I am coming from the beach.)
  C'est le livre de Marie. (It is the book of Marie / Marie's book.)

Geographic Rules: Cities and Countries

When talking about travel and locations, the rules are extremely strict and depend on whether you are talking about a city or a country.

• Cities: Always use à for being in/going to a city, and de for coming from it.
  J'habite à Paris. Je rentre de Londres.
• Countries: This is where à steps aside. For feminine countries (ending in -e, like France), use en to mean "in/to". For masculine countries, use au.
  Je vais en France et au Canada.

The Real Challenge: Verb Pairings

The hardest part of à vs de isn't location; it's the fact that many French verbs demand a specific preposition before an infinitive verb, regardless of how it translates to English. You simply have to memorize these pairings!

Common verbs followed by "À" (Focusing on a goal/future action):

• Aider à (to help to): Il m'aide à étudier.
• Apprendre à (to learn to): J'apprends à parler français.
• Commencer à (to start to): Il commence à pleuvoir.

Common verbs followed by "DE" (Focusing on separation, completion, or facts):

• Oublier de (to forget to): J'ai oublié de l'appeler.
• Essayer de (to try to): J'essaie de dormir.
• Arrêter de (to stop doing): Arrête de parler !

The Contraction Reminder

Don't forget that both à and de must contract when they meet the masculine articles le or les.
(à + le = au, à + les = aux)
(de + le = du, de + les = des).
