Y pour les choses, à + tonique pour les personnes

Before this page: Quel pronom ? Le déterminant et la construction décident — the decision table that says when a group becomes le, en, y or lui. This page is the detail of one row. Which verbs keep à + a tonic pronoun for a person, and which take lui/leur, is sorted verb by verb on Personne ou chose : quand le pronom quitte le verbe.
The pronoun pillar opens on the distinction immersion almost never repairs: what replaces à + noun depends on whether that noun is a thing or a person.
Things and places → y, placed before the verb:
- Tu penses à ton projet ? — Oui, j'y pense.
- Vous tenez à cette photo ? — Oui, nous y tenons.
- Tu participes au débat ? — Oui, j'y participe.
People, with verbs like penser à, tenir à, songer à → keep à + tonic pronoun after the verb:
- Tu penses à ta sœur ? — Oui, je pense à elle. (not j'y pense)
- Il tient à sa grand-mère ? — Oui, il tient beaucoup à elle.
Why these verbs resist the clitic: their à-complement is not a recipient but something closer to a fixed preposition phrase, and French reserves the tonic forms — moi, toi, lui, elle, eux, elles — for people held inside a preposition.
One boundary to respect: most à + person verbs (téléphoner à, parler à, répondre à) take lui/leur before the verb instead — je lui téléphone, never je téléphone à elle. That system gets its own unit; here you only need the penser/tenir/songer family. The practice alternates thing and person until the fork is automatic.
Going further
Everything y can replace. Three kinds of group, and only these:
| The group | Example | With y |
|---|---|---|
| à + a thing or an idea | Je crois à cette idée. | J'y crois. |
| a place with à, en, dans, chez, sur, sous | Elle habite en Provence. | Elle y habite. |
| a fixed expression | Ça y est. On y va. Vas-y. Il y a. | — |
A place you come from is not y but en: Tu viens de Lyon ? — J'en viens. And y never replaces a person — for people the verb decides, and the verbs are sorted on Personne ou chose.
Minimal pairs with one verb. Croire shows the whole system at once: je le crois (I believe him — direct), j'y crois (I believe in it — à + idea), je crois en lui (I believe in him — a person keeps the preposition).
The errors to watch.
| Said | Correct | Why |
|---|---|---|
| Je lui pense. | Je pense à lui. | penser à + person keeps à + tonic |
| (à la lettre) J'en ai répondu. | J'y ai répondu. | à + thing → y, whatever the determiner |
| Tu es allée au centre ? — Oui, je suis déjà allée. | Oui, j'y suis déjà allée. | a place already mentioned comes back as y — the answer cannot leave it out |
| Je vais aller y demain. | Je vais y aller demain. | with aller + infinitive, y sits before the infinitive — see Où va le pronom ? |
In Russian там ("there") is optional and free in position; French y is required once the
place is known and sits in a fixed slot before the verb: Tu vas au marché ? — Oui, j'y vais,
not oui, je vais.
The decision that comes before this page — is it y at all? — is on Quel pronom ?.

Oui / non drill
A question, then two answers to write: the oui answer and the non answer, each with the complement replaced by its pronoun. Every answer is graded, and a wrong one names the rule it breaks.
