Adverbial Pronouns y and en (intermediate use)

What are the adverbial pronouns y and en?

Adverbial pronouns y and en are short French pronouns that replace prepositional phrases (usually phrases that begin with à, de, or place prepositions like dans/chez/sur). They are called "adverbial" because they stand in for complements that act like adverbs (place, source, quantity). In everyday English you can think of y as roughly "there/to it/at it" and en as roughly "of it/from it/some/any."

Simple examples:
- "Je vais à Paris." → "J'y vais." (I am going there.)
- "Tu veux du pain ?" → "Oui, j'en veux." (Do you want some? — Yes, I do.)

When do I use y?

y replaces place expressions
- Use y when the complement expresses a place, often introduced by à, dans, sur, sous, chez, devant, etc.
- "Je vais chez Marie." → "J'y vais." (I'm going to Marie's / I'm going there.)
- "Le livre est sur la table." → "Il y est." (It is there.)

y replaces "à + thing" (not persons)
- Many verbs take an object introduced by à (penser à, répondre à, jouer à, croire à, s'habituer à...). If the object is a thing or an idea, you can replace it with y.
- "Je réponds à la question." → "J'y réponds." (I answer it.)
- "Elle pense à son avenir." → "Elle y pense." (She thinks about it.)
- "Il joue au piano." → "Il y joue." (He plays it.)

Important restriction: y does NOT replace people as indirect objects
- When à introduces a person (indirect object), use lui / leur (or a tonic pronoun in some contexts), not y.
- Wrong: *"Je y parle." Correct: "Je lui parle." (I speak to him/her.)
- Exception: if the phrase with a person expresses a place ("chez + person"), y can replace it: "Je vais chez Paul." → "J'y vais." (I go to Paul's.)

When do I use en?

en replaces de + noun (partitive, indefinite, or after verbs/adjectives that require de)
- Use en for complements introduced by de (partitive du/de la/des, or after verbs/adjectives with de: parler de, avoir besoin de, se souvenir de, manquer de, etc.).
- "Tu veux du chocolat ?" → "Oui, j'en veux." (Yes, I want some.)
- "Il parle de son projet." → "Il en parle." (He talks about it.)
- "Nous avons besoin d'aide." → "Nous en avons besoin." (We need it/We need help.)

en expresses quantity or replaces "de + number"
- If the phrase contains a number or quantity, en stands in and the number remains after the verb:
- "Combien de frères as-tu ?" → "J'en ai deux." (How many brothers? I have two.)
- "J'ai acheté trois pommes." → "J'en ai acheté trois." (I bought three of them.)

en can replace origin or source (venir de...) and is used in some idioms
- "Je viens de Lyon." → "J'en viens." (I come from there.)
- "Il s'en va." (He leaves.)
- "Je m'en sors." (I manage/get by.)

Note about definite objects
- en replaces complements introduced by de (including partitives and indefinite quantities). It does NOT normally replace a direct object introduced by the definite article (le/la/les) — in that case use le/la/les: "Tu connais le livre ?" → "Oui, je le connais." (Not *"J'en connais" unless meaning "I know of it/one").

Where are y and en placed (word order)?

Before a simple conjugated verb
- Put y or en immediately before the verb:
- "J'y vais." (I'm going there.)
- "J'en veux." (I want some.)

Before the auxiliary in compound tenses
- In compound tenses (passé composé, plus-que-parfait, etc.) they come before the auxiliary (être or avoir):
- "J'y suis allé(e)." (I went there.)
- "J'en ai parlé." (I spoke about it.)

With an infinitive (verb + infinitive)
- If there is an infinitive, place y/en before the infinitive (they belong to the infinitive):
- "Je vais y aller." (I'm going to go there.)
- "Je veux en parler." (I want to talk about it.)
- Negative with infinitive: the negative surrounds the conjugated verb, but pronoun stays with the infinitive: "Je ne vais pas y aller." / "Je ne veux pas en parler."

In negative sentences and questions
- Negative: "Je n'y vais pas." / "Je n'en veux pas." / "Ne m'en parle pas !"
- Question (inversion or est-ce que): "Y vas-tu ?" or "Est-ce que tu y vas ?" / "En veux-tu ?" or "Est-ce que tu en veux ?"

Affirmative imperative vs negative imperative
- Affirmative commands: attach pronouns to the verb with hyphens; use "moi"/"toi" forms instead of "me"/"te":
- "Parle-moi-en !" (Tell me about it!)
- "Donne-m'en !" (Give me some!)
- "Vas-y !" (Go there / go ahead!)
- "Va-t'en !" (Go away!)
- Negative commands: pronouns are placed before the verb as usual:
- "Ne m'en parle pas !" (Don't tell me about it!)
- "Ne t'y rends pas !" (Don't go there!)

How do y and en combine with other pronouns?

Order of object pronouns before the verb (normal word order)
- The usual order is: me / te / se / nous / vous → le / la / les → lui / leur → y → en
- Examples:
- "Tu m'en as parlé." (You told me about it.) — me before en
- "Je lui en ai parlé." (I spoke to him/her about it.) — lui before en
- "Je t'y emmène." (I'll take you there.) — te before y

Order in affirmative imperative (different order and forms)
- After the verb (hyphenated): le / la / les → moi / toi / lui / nous / vous / leur → y → en
- "Donne-le-moi !" (Give it to me!)
- "Parle-moi-en !" (Talk to me about it!)
- "Donne-leur-en !" (Give them some of it!)

Do y and en affect past-participle agreement?

- Important: With avoir, the past participle agrees in gender and number with a preceding direct object pronoun (le / la / les). But y and en are not treated like those direct object pronouns for agreement.
- Example with direct object pronoun (agreement):
- "J'ai pris les pommes." → "Je les ai prises." ("prises" agrees with "les" = les pommes)
- The same idea replaced with en (no agreement):
- "J'ai pris des pommes." → "J'en ai pris." (No agreement on "pris")
- y never triggers agreement (it usually replaces places or à + thing). Example: "Je suis allé au cinéma." → "J'y suis allé(e)." The participle agrees with the subject (because the auxiliary is être), not with y.

Common mistakes to avoid

1. Using y for people introduced by à
- Wrong: *"Je y parle à Paul." Correct: "Je lui parle." (I speak to Paul.)
- Right exception: "Je vais chez Paul." → "J'y vais." (Because chez Paul is a place)

3. Wrong placement with infinitives or compound tenses
- Wrong: *"J'y vais aller." Correct: "Je vais y aller." (pronoun before infinitive)
- Wrong: *"Je y ai parlé." Correct: "Je lui en ai parlé." (pronouns before auxiliary in compound tenses)

4. Expecting agreement with en
- Wrong: *"J'en ai mangées." Correct: "J'en ai mangé." (no agreement with en)

5. Imperative position mistakes
- Affirmative: attach ("Parle-moi-en !"), negative: place before verb ("Ne m'en parle pas !").

Special notes, idioms and tricky pairs

- "Il y a" vs "Il y en a":
- "Il y a des questions." → "Il y en a." (There are some.)
- For a precise count: "Il y a trois personnes." → "Il y en a trois." (There are three of them.)

- Origin vs destination:
- "Tu viens de Paris ?" → "Oui, j'en viens." (I come from there.)
- "Tu vas à Paris ?" → "Oui, j'y vais." (I'm going there.)

- Fixed/idiomatic uses:
- "S'en aller" → "Il s'en va." (to go away)
- "S'y connaître" → "Il s'y connaît en vin." (He knows about wine)
- "Ça y est !" (That's it / It's done) — idiomatic use of y

Quick decision guide (short rules you can use right away)

- If the phrase is introduced by à (place or à + thing) → try y. If the complement is a person after à → use lui/leur.
- à Paris → y ; à la question → y ; à Paul → lui/leur.
- If the phrase is introduced by de (partitive, possession after de, origin, quantity) → use en.
- du pain / de la confiture / des amis / venir de → en.
- Place pronoun before a conjugated verb or before the auxiliary in compound tenses; before an infinitive if it belongs to the infinitive; attach with hyphens in affirmative commands; keep pronoun inside the negative frame (ne ... pas).
- For numbers: use en and keep the number after the verb: "J'en ai trois." (I have three of them.)

Glossary

Adverbial pronoun — a short pronoun that replaces a complemento (of place, source, quantity) rather than a direct person noun.
Partitive article — du / de la / de l' / des ("some" in English).
Prepositional complement — a phrase that begins with a preposition like à, de, dans, sur, chez (it often expresses place, origin, or possession).
Auxiliary — the helping verb (avoir or être) used to form compound tenses (e.g., j'ai, je suis).

Summary

- y replaces places and "à + thing" (not people as indirect objects); it means roughly "there" or "to it." Example: "J'y vais." (I go there.)
- en replaces "de + noun" (partitives, quantities, origin); it means roughly "of it / some / from it." Example: "J'en prends." (I'll take some.)
- Pronouns go before the verb (or auxiliary) except in affirmative commands, and en does not trigger past-participle agreement.

If you remember two simple checks — "Is the original phrase introduced by à (place/thing)? Use y — Is it introduced by de (some/of/from/quantity)? Use en" — you will be correct in most intermediate situations. For tricky idioms and some verbs learn the verb+preposition pairing (penser à vs parler de, venir de vs aller à) and practice the pronoun placement rules (before conjugated verb, before infinitive, attach on affirmative imperatives).
