How to Choose Between 'En' and 'Dans' in French

Using 'En' and 'Dans' for Time

When talking about time, 'en' and 'dans' create one of the most common points of confusion for learners. 'En' is used for months, seasons, and years.

• Months: J'ai un examen **en** mai. (I have an exam in May.)
• Seasons: Il neige beaucoup **en** hiver. (It snows a lot in winter.) The one exception is spring, which uses 'au': **au** printemps.
• Years: Nous avons déménagé **en** 2023. (We moved in 2023.)

The key difference appears when discussing a duration of time. Use 'en' for the amount of time it takes to complete an action. Use 'dans' to indicate a point in the future when something will happen.

For decades, French speakers use 'dans', as in 'la mode **dans** les années 80' (fashion in the 80s).

For talking about time, the words 'pendant', 'depuis', and 'il y a' have their own specific rules and are covered in separate guides.

'Dans': Inside a Specific Place

The most straightforward use of 'dans' is to mean 'inside' or 'within' a specific, enclosed, or clearly defined space. It is almost always followed by a determiner like an article (le, la, un, une) or a possessive adjective (mon, ma, tes).

• Le chat est **dans** la maison. (The cat is in the house.)
• Qu'est-ce que tu as **dans** ton sac ? (What do you have in your bag?)
• Il y a de bons restaurants **dans** ce quartier. (There are good restaurants in this neighborhood.)

'En': General Locations and Feminine Countries

In contrast, 'en' often refers to a more general or abstract location. It is frequently used in fixed expressions and is typically not followed by an article.

• Je vais **en** ville. (I'm going downtown/to the city center.)
• Les enfants sont **en** classe. (The children are in class.)
• Elle est **en** vacances au bord de la mer. (She is on vacation by the sea.)

'En' is also the correct preposition to use before feminine countries and continents.

• Nous habitons **en** France. (We live in France.)
• Il rêve de voyager **en** Asie. (He dreams of traveling in Asia.)
• Mon amie travaille **en** Allemagne. (My friend works in Germany.)

The rules for prepositions with all countries, continents, and cities are detailed in their own dedicated resource.

Transportation: 'En', 'À', and 'Dans'

For modes of transport, the general rule is to use 'en' for vehicles you get inside.

• voyager **en** train (to travel by train)
• aller **en** voiture (to go by car)
• monter **en** avion (to get on a plane)
• se déplacer **en** bus (to get around by bus)

For modes of transport you are 'on' (or that are human-powered), you use 'à'.

• **à** pied (on foot)
• **à** vélo (by bike)
• **à** moto (by motorbike)
• **à** cheval (on horseback)

You can use 'dans' to emphasize being physically inside a specific vehicle. Compare 'Je voyage en train' (I travel by train, a general statement) with 'Je suis **dans** le train pour Lyon' (I am inside the specific train to Lyon).

In everyday speech, you will hear both 'à vélo' and 'en vélo'. While 'à vélo' is traditionally considered more correct, 'en vélo' is very common and widely understood.

Using 'En' for Materials

To describe what something is made of, you always use 'en'.

• une table **en** bois (a wooden table)
• une bague **en** or (a gold ring)
• un pull **en** laine (a wool sweater)
• une bouteille **en** verre (a glass bottle)

Other Key Uses of 'En'

'En' appears in many common expressions to describe a state, a language, or how someone is dressed.

• **State or Condition:** être **en** forme (to be in shape), être **en** colère (to be angry), la voiture est **en** panne (the car has broken down).
• **Language:** un texte écrit **en** espagnol (a text written in Spanish), un film **en** version originale (a film in its original version).
• **Clothing:** Il est toujours **en** jean. (He always wears jeans.), une femme **en** noir (a woman in black).
