Les verbes pronominaux
A verbe pronominal is a verb conjugated with a reflexive pronoun (me, te, se, nous, vous, se) that matches the subject. They are everywhere in French — and they come in four distinct flavors that mean very different things even though they share the same surface shape: réfléchis (the subject does something to itself), réciproques (the subjects do something to each other), idiomatiques (the pronoun is just part of the verb's meaning), and passifs (the pronoun marks a passive-like 'gets done'). All four use être as the auxiliary in compound tenses, but the agreement of the past participle depends on whether the reflexive pronoun functions as a direct or indirect object.
Réfléchis — the subject acts on itself
The subject does the action to themselves. The reflexive pronoun is the direct object. Je me lave. = I'm washing (myself). Elle se regarde dans le miroir. = She looks at herself in the mirror. Nous nous habillons. = We're getting dressed. Many verbs of personal care work this way: se laver, se doucher, se raser, se peigner, se maquiller, se coucher, se lever, s'habiller, se déshabiller, se réveiller. If the verb is followed by a body part or a piece of clothing as a true direct object, the reflexive pronoun becomes indirect: Je me lave les mains. = I'm washing my hands. (Here me = 'to/for myself', and les mains is the COD.) This distinction matters for participle agreement (next section).
Réciproques — the subjects act on each other
When the subject is plural, the pronoun can mean 'each other' rather than 'themselves'. Ils se parlent. = They talk to each other. Nous nous écrivons souvent. = We write to each other often. Marc et Sophie se sont rencontrés à Paris. = Marc and Sophie met (each other) in Paris. To force the reciprocal reading and rule out the reflexive one, French often adds l'un l'autre / les uns les autres: Ils se regardent l'un l'autre. = They're looking at each other. As with réfléchis, the pronoun can be direct (se rencontrer = meet each other; se is COD) or indirect (se parler = talk to each other; se is COI, because parler à quelqu'un).
Idiomatiques — the pronoun is part of the meaning
Some verbs exist as pronominal verbs and either have no non-pronominal counterpart or mean something completely different without the se. The reflexive pronoun is not analyzable as a separate object — it's just glued to the verb. se souvenir de = to remember (compare souvenir = a memory, the noun). se passer = to happen (Qu'est-ce qui se passe? = What's going on?). se taire = to be silent. se moquer de = to make fun of. s'apercevoir de = to notice. s'en aller = to leave. se rendre compte de = to realize. Some verbs change meaning radically: rendre = to give back, but se rendre compte = to realize; passer = to pass, but se passer = to happen; mettre = to put, but se mettre à = to start to.
Passifs — 'it gets done'
With a non-human subject, a pronominal verb can have a passive sense: 'X se verb' = 'X is verb-ed / gets verb-ed / is verb-able'. Ça se mange. = That's edible / That can be eaten. Le vin blanc se boit frais. = White wine is drunk chilled. Ce mot ne se dit pas. = That word isn't said / shouldn't be said. Les livres se vendent bien. = The books are selling well. This is a useful alternative to the voix passive (lesson 30) when no specific agent is involved. It's especially common in instructions, recipes, and general statements: Ce plat se sert chaud. = This dish is served hot.
Past tense — auxiliary être, agreement rules
ALL pronominal verbs use être in compound tenses. Je me suis lavé. Elle s'est levée. Nous nous sommes parlé. Agreement of the past participle is the tricky part: agree with the reflexive pronoun only when it is a direct object. Three sub-cases. (1) Pronoun is COD → agree with subject: Elle s'est lavée. = She washed (herself); se is COD, feminine subject → lavée. (2) Pronoun is COI → no agreement: Elle s'est lavé les mains. = She washed her hands; here se = 'to herself' (COI), and les mains is the COD that comes AFTER, so no agreement → lavé. (3) Idiomatic / inherently pronominal verbs → agree with subject by default: Elle s'est souvenue. = She remembered. (4) Reciprocals: agree only if the pronoun is COD: Ils se sont vus. (vs Ils se sont parlé. — parler à, so se is COI, no agreement.)
The COD-after-verb exception (the classic trap)
Compare Elle s'est lavée. vs Elle s'est lavé les mains. Same verb, different agreement. The rule is: the participle agrees with a direct object only if that direct object precedes the verb. In Elle s'est lavée, se = COD (= 'herself') and precedes the verb → agreement. In Elle s'est lavé les mains, the COD is les mains, which comes AFTER the verb → no agreement. The se is just the indirect object 'to/for herself'. Same pattern with body parts and clothing: Elle s'est coupé le doigt. = She cut her finger. Elle s'est cassé la jambe. = She broke her leg. No agreement, because the COD (le doigt, la jambe) follows the verb. But: La jambe qu'elle s'est cassée. = The leg she broke — now la jambe precedes (via the relative pronoun), so agreement comes back.
Quick recap
(1) Four flavors: réfléchis (self), réciproques (each other), idiomatiques (just the verb's meaning), passifs (gets done; non-human subject). (2) Auxiliary in compound tenses: always être. (3) Agreement: only when the reflexive pronoun is the COD. (4) Trap: with a body part / object as the COD coming after, the reflexive becomes COI and there is no participle agreement: Elle s'est lavé les mains. (5) Idiomatic verbs default to subject agreement: Elle s'est souvenue.
