Reflexive passé composé: agreement and the body-part trap

~2 min readLast updated: 2026-05-01

The Passé Composé — The Reflexive Trap

Some reflexive verbs can be tricky when it comes to past participle agreement.

The key is to check if the verb has a direct object (COD) after it.


The Big Idea: Agreement Depends on the COD

  • If the reflexive verb acts only on the subject, the past participle agrees in gender and number.
  • If the verb is followed by a COD, the past participle does not agree — it stays in the masculine singular form.

Examples

FrenchEnglishExplanation
Elle s’est lavée.She washed herself.The action is on herself → agreement with subject (feminine singular)
Elle s’est lavé les mains.She washed her hands.The direct object “les mains” comes after the verb → no agreement

How to Decide Quickly

  1. Ask: What or who is being washed / acted on?
  2. If it’s the subject itself only, add agreement.
  3. If the action affects something else (COD) after the verb, no agreement.

Key Points

  • Reflexive verbs usually agree with the subject.
  • Exception: when a direct object (COD) comes after the verb, the past participle stays unchanged.
  • Common with body parts: se laver les mains, se brosser les dents, se coiffer les cheveux.

Key Takeaways

  • Always check for a direct object after the verb.
  • Agreement = subject only, no COD → Elle s’est lavée
  • No agreement if COD comes after → Elle s’est lavé les mains
  • This is a common pitfall in French reflexive verbs.
