What is Passive Voice in French?

Passive voice in French transforms the sentence structure—the object becomes the subject, and the action is performed by an agent introduced by par or de. It's essential for formal writing and literature.

Short answer

Passive voice uses être + past participle, with par (agent) or de (instrument/agent). 'Marc écrit une lettre' becomes 'Une lettre est écrite par Marc' (A letter is written by Marc).

Active vs Passive Voice

Active

•Subject performs action
•Marc (who)
•écrit (verb)
•une lettre (object)

Passive

•Object becomes subject
•Une lettre (who)
•est écrite (verb)
•par Marc (agent)

Step-by-step worked examples

Transform active to passive: 'Les étudiants étudient le français.'

Active: Les étudiants (subject) étudient (verb) le français (object).
Passive: Le français est étudié par les étudiants.
Rule: object → subject, verb → être + past participle.

Transform: 'Marie a peint la maison.'

Active: Marie (subject) a peint (verb) la maison (object).
Passive: La maison a été peinte par Marie.
Note: être (a) + past participle of peindre.

Use 'de' instead of 'par': 'Ils respectent leurs parents.'

Active: Ils respectent leurs parents.
Passive with de: Les parents sont respectés de leurs enfants.
Use de with feelings, qualities, or when agent is obvious.
