Tu vas à Paris ? Oui, j'y vais demain.Are you going to Paris? Yes, I'm going there tomorrow.

Instead of repeating a place or a thing you've already mentioned, French often uses the small word y. It stands in for à (or another place word) + that place or thing, and it slots into the sentence right where an object pronoun goes: before the verb.

Quick shortcut: y goes right before the verb and replaces à + a place or a thing/idea — never a person.

Standing in for a place: y = "there"

The most common use of y is to replace a place that's already been mentioned, most often introduced by à:

  • Tu vas à la banque ?Oui, j'y vais. (Yes, I'm going there.)
  • Il habite à Lyon.Il y habite. (He lives there.)
  • Elle travaille au musée.Elle y travaille. (She works there.)

y isn't limited to à — it can replace a place introduced by another preposition too (dans, sur, chez...), since all it really means is "there":

  • Le chat dort sur le canapé.Il y dort. (It sleeps there.)
  • Tu vas chez Marc ce soir ?Oui, j'y vais. (Yes, I'm going there.)

Standing in for à + a thing or an idea

y also replaces à + a thing or idea with a small set of common verbs — penser à, réfléchir à, répondre à, jouer à, s'intéresser à, participer à and similar:

  • Tu penses à l'examen ?Oui, j'y pense. (Yes, I'm thinking about it.)
  • Il faut réfléchir à ce problème.Il faut y réfléchir. (We need to think it over.)
  • Tu joues au tennis ?Oui, j'y joue. (Yes, I play it.)

y never replaces à + a person (chez Marc above is still a place, not an exception to this — it's chez, not à). For a person, other pronouns take over — usually an indirect object pronoun like lui/leur (its own separate topic), but a handful of verbs, penser à among them, instead use a stressed pronoun:

  • Tu penses à Léa ? Oui, je pense à elle. — never ❌ Oui, j'y pense (for a person).

Right before the verb, just like other object pronouns

y follows the same word-order rules as the direct object pronouns: it sits immediately before the conjugated verb, and before an infinitive when there is one — except in the affirmative imperative, covered next.

  • J'y vais. — never ❌ Je vais y.
  • Elle ne va pas y aller ce soir. (She's not going to go there tonight.)
  • Tu vas y réfléchir ? (Are you going to think about it?)

In a negative sentence, ne... pas wraps around y and the verb together:

  • *Je **n'*y vais pas. (I'm not going there.)
  • *Il **n'*y pense pas. (He doesn't think about it.)

Vas-y! The imperative gets an extra -s

In the affirmative imperative, y attaches right after the verb with a hyphen, exactly like a direct object pronoun does. With an -er verb's tu form, an extra -s is added before y purely to make the two words easier to say out loud:

  • VaVas-y ! (Go on! / Go there!) — never ❌ Va-y !
  • Restes-y. (Stay there.)

This -s shows up only in this exact spot — before y or en (its own separate topic) in the tu imperative of an -er verb — and doesn't change the verb's meaning or tense.

Two everyday fixed phrases

Two expressions built on y are worth knowing as set phrases from the start:

  • On y va ! (Let's go! / We're off!)
  • Ça y est ! (That's it! / Done!)

y also shows up inside il y a ("there is / there are") — that's the same little word, but il y a behaves as one fixed expression rather than y standing in for something just mentioned, and it has its own rules.

Common mistakes

  • Je vais à y. → ✅ J'y vais. (y already carries the meaning of à — don't add it again)
  • Je vais y. → ✅ J'y vais. (y goes before the verb, not after)
  • Va-y ! → ✅ Vas-y ! (the tu imperative of an -er verb adds -s before y)
  • Tu penses à Léa ? Oui, j'y pense. → ✅ Oui, je pense à elle. (y never replaces a person)

  1. Tu vas à la poste ?Tu ____ vas ?
  2. Il pense à son voyage.Il ____ pense.
  3. Va au tableau !____ !
  4. Elle ne répond pas à ce message.Elle ne ____ répond pas.
  5. Nous allons chez nos amis ce week-end.Nous ____ allons ce week-end.

Key takeaways

  • y replaces à + a place ("there") or à + a thing/idea ("about it", "in it") that's already been mentioned — never a person.
  • It can also stand for a place introduced by another preposition (dans, sur, chez...), since its core meaning is simply "there".
  • Like other object pronouns, y goes right before the conjugated verb, or right before an infinitive when there's one — except in the affirmative imperative, where it attaches after: j'y vais, je vais y réfléchir, but Vas-y !
  • In the negative, ne... pas wraps around y and the verb: je n'y vais pas.
  • In the affirmative imperative, y attaches after the verb with a hyphen, and an -er verb's tu form adds an extra -s: Vas-y !
  • On y va ! and Ça y est ! are everyday fixed phrases built on y; the y inside il y a is part of that separate fixed expression.
