"Are you going to the party?" "Yes, I'm going." "Do you have any brothers?" "Yes, two." In English, these answers are perfectly natural. Now try the same thing in French:
- ❌ Tu vas à la fête ? — Oui, je vais.
- ❌ Tu as des frères ? — Oui, j’ai deux.
A French speaker will understand you, but both answers sound cut off, like "I'm going…" trailing into silence. The correct versions are Oui, j’y vais and Oui, j’en ai deux. Two tiny words, y and en, that English learners drop more than almost anything else.
🧩 Why French needs y and en
The key difference: a French verb does not like to be left alone. If the verb had a complement (where? of what? how many of what?), that complement has to stay in the sentence, even as a tiny pronoun. English happily drops whatever is clear from context. French doesn't.
| Word | What it replaces | English hint |
| y | à / dans / chez / sur + a place; à + a thing or idea | "there", which English usually leaves out |
| en | de + something; du / de la / des + noun; a quantity | "some", "any", "of it", "of them" |
y: the "there" you cannot skip
Je vais à Paris → J’y vais. → I'm going (there). Je suis au bureau → J’y suis. → I'm there. In English, "there" is optional. In French, once the place has been mentioned, y is required.
y also replaces à + a thing or an idea: Tu penses à ton examen ? — Oui, j’y pense tout le temps. → Are you thinking about your exam? Yes, I think about it all the time. English says "about it"; French uses y because the verb penser takes à.
en: the French "some" and "of them"
English actually gives you a great clue here. Whenever you could say "some", "any", "of it" or "of them", French needs en, and unlike English, it can't leave it out:
- Tu veux du thé ? — Oui, j’en veux bien. → Do you want some tea? Yes, I'd love some.
- Tu as des enfants ? — Oui, j’en ai trois. → Do you have children? Yes, I have three (of them).
- Il parle de son voyage ? — Oui, il en parle sans arrêt. → Is he talking about his trip? Yes, he talks about it nonstop.
The rule of thumb: if your English answer ends with a bare number or quantity ("three", "a lot", "a little"), French almost certainly needs en. The number stays at the end: j’en ai trois, j’en veux un peu, il y en a beaucoup.
📍 Where do y and en go?
Both words go before the verb, which feels backwards to English speakers:
- Present tense: j’y vais, j’en prends.
- Negation wraps around the pronoun and the verb together: je n’y vais pas, je n’en veux pas.
- Passé composé: before the auxiliary, j’y suis allé, j’en ai acheté.
- With an infinitive: before the infinitive, je vais y aller, je voudrais en goûter.
- The exception is the positive imperative, where the pronoun follows the verb with a hyphen: Vas-y !, Prends-en !
Notice vas-y: the imperative of aller is normally va ! with no s, but the s comes back before y to make it easier to say.
📖 A real example: "La cabane dans l’arbre"
Let's watch y and en at work in a real text. Here is the opening of "La cabane dans l’arbre" (The Treehouse) on Linguami, a childhood memory:
Quand j’étais petite, j’adorais grimper aux arbres. C’était ma passion, et dès que j’en avais l’occasion, je grimpais partout — sur les murs, les clôtures, et surtout les arbres. Dans notre rue, il y en avait beaucoup, mais celui que je préférais poussait juste dans notre cour.
- dès que j’en avais l’occasion: whenever I had the chance (to do it). en replaces de grimper, because French says avoir l’occasion de faire quelque chose. English simply leaves "to do it" out.
- il y en avait beaucoup: there were lots of them, meaning trees. en replaces d’arbres, and the quantity beaucoup stays in place. The English translation even shows you the slot: "of them".
Watch out for a trap: il y en avait contains two small words, but only one of them is a pronoun. Il y avait ("there was / there were") is the fixed expression il y a, and its y doesn't replace anything. The pronoun here is en.
A little further on, y shows up as a real pronoun:
Bien sûr, notre cabane était minuscule — on pouvait à peine s’y asseoir à deux — mais nous l’adorions. Elle est devenue notre refuge secret. Nous y montions presque tous les jours après l’école. Parfois, nous y apportions des biscuits et du jus de fruits, et nous faisions semblant d’être des explorateurs perdus dans la jungle.
Three times y, and each time it means the treehouse: two of us could barely sit in it, we climbed up there almost every day, we brought cookies up there. English could drop "there" or "in it". French can't.
In the full text, click any word to see its translation and its grammatical form. If the story feels long for now, start with the short beginner dialogue "Au marché": the vendor weighs the grapes and asks J’en ai mis 400, c’est trop ? → I put 400 grams in, is that too much? And in "Plat préféré", Pierre describes French cheeses: il y en a à l’ail et aux herbes, il y en a avec de la moisissure.
⚠️ Common mistakes English speakers make
1. A bare number without en
❌ J’ai deux sœurs. Et toi ? — J’ai une. ✅ J’en ai une. "I have one" works in English; in French, a number can't stand alone without en holding the noun's place.
2. Aller without y
❌ Tu vas au cinéma ce soir ? — Oui, je vais. ✅ Oui, j’y vais. Without a place or an infinitive after it, "je vais" sounds like an unfinished thought.
3. y for a person
❌ Tu penses à ta mère ? — Oui, j’y pense. ✅ Oui, je pense à elle. In standard French, y replaces places, things and ideas, not people. For people, use lui / leur (je lui parle), or à lui / à elle after a few verbs such as penser.
4. Putting the pronoun after the verb
❌ J’ai pris en deux. ✅ J’en ai pris deux. ❌ Je vais pas y. ✅ Je n’y vais pas. English word order pulls "some" and "there" to the end of the sentence; French pulls y and en to the front of the verb.
💬 Expressions to learn as a whole
y and en appear in dozens of everyday expressions where it's no longer obvious what they replace. It's easier to learn them as ready-made chunks:
- On y va ! → Let's go!
- Vas-y ! / Allez-y ! → Go ahead! Go for it!
- Ça y est ! → That's it! Done!
- Je m’en vais. → I'm leaving.
- J’en ai marre. → I'm fed up.
- Je n’en peux plus. → I can't take it anymore.
- Je m’en fiche. → I don't care.
🚀 How to master y and en
- Take the lesson Indirect-object pronouns, y and en (A2): the rule, examples and exercises.
- If le / la / les and lui / leur still get mixed up, start with Direct-object pronouns (le, la, les).
- Once you're comfortable, move on to Double object pronouns (B1): how to say je lui en ai parlé.
- When you read, underline every y and en and ask yourself what it replaces. After a dozen texts, you'll start to hear where they're missing.
