Using the French Prepositions 'En' and 'Dans'

These two French prepositions are not interchangeable

In French, the prepositions en and dans both mean "in," and they both express time and location. They are not, however, interchangeable. Their usage depends on both meaning and grammar. Practice usage with a test on en vs. dans.

How French Prepositions Work

In French, prepositions are generally words that link two related parts of a sentence. They are usually placed in front of nouns or pronouns to indicate a relationship between that noun or pronoun and a verb, adjective or noun that precedes it.

  • I'm talking to Jean.
  • Je parle à Jean.
  • She is from Paris.
  • Elle est de Paris.
  • The book is for you. 
  • Le livre est pour toi.

These small but powerful words not only show relationships between words, they also refine the meanings of place (cities, countries, islands, regions, and U.S. states) and time (as with pendant and durant); can follow adjectives and link them to the remainder of a sentence; can never end a sentence (as they can in English); can be difficult to translate into English and idiomatic; and can exist as a prepositional phrase, such as au-dessus de (above), au-dessous de (below), and au milieu de (in the middle of).

Some prepositions are also used after certain verbs to complete their meaning, such as croire en (to believe in), parler à (to talk to) and parler de (to talk about). Plus, prepositional phrases can be replaced by the adverbial pronouns y and en.

The following guidelines and examples delineate how and when to use two of the trickier French prepositionsen and dans. Notice how they link two related parts of each sentence. 

Examples of When to Use 'En' in French

En expresses the length of time an action happens. As a result, the verb is usually in the present or past tense, as in

  • Je peux faire le lit en cinq minutes.
  • I can make the bed in five minutes.
  • Il a lu le livre en une heure. 
  • He read the book in an hour.
  • J'ai appris à danser en un an. 
  • I learned how to dance in a year.

En expresses when an action happens as it relates to the calendar: month, season, or year. Exception: au printemps.

  • Nous voyageons en Avril.
  • We travel in April.
  • Il arrivera en hiver. 
  • He will arrive in the winter.

En can mean "in" or "to" when followed directly by a noun that doesn't need an article:

  • Vous allez en prison! 
  • You're going to prison! 
  • Il est en classe. 
  • He's in school.

En can also mean "in" or "to" when used with some states, provinces, and countries, such as

  • J'habite en Californie.
  • I live in California.
  • Je vais en France.
  • I'm going to France.

Examples of When to Use 'Dans'

Dans indicates the amount of time before action will occur. Note that the verb is usually in the present or future, as in

  • Nous partons dans dix minutes.
  • We're leaving in 10 minutes.
  •  Il reviendra dans une heure.
  • He'll be back in an hour. 
  • Elle va commencer dans une semaine.
  • She's going to start in a week.

Dans refers to something that occurs within or during a decade, as in

  • Dans les années soixantes...
  • In the sixties...
  • Dans les années quatre-vingts...
  • During the eighties...

Dans means "in" a location when followed by an article plus noun, such as

  • Il est dans la maison.
  • He's in the house. 
  • Qu'est-ce qui est dans la boîte?
  • What's in the box?

Dans also means "in" or "to" with some states and provinces:

  • J'habite dans le Maine.
  • I live in Maine.
  • Je vais dans l'Ontario.
  • I'm going to Ontario.
