Questions & Answers about Le texte est traduit par un traducteur professionnel.
How do we form the passive voice in this sentence?
Just like in English! You use the present tense of the verb être (here, est) followed by the past participle of the main verb (traduit). The person doing the action is introduced by the preposition par (by).
Does the past participle traduit need to agree with the subject?
Yes! In the passive voice, the past participle acts like an adjective and must agree in gender and number with the subject. Since Le texte is masculine singular, traduit takes no extra ending. If it were a feminine noun, like La lettre, it would be est traduite.
Could I use de instead of par to mean "by" in this sentence?
Not here. The word par is the standard preposition for the passive voice when describing a specific, active action like translating. You only use de to mean "by" for states of being or verbs of emotion, like aimé de (loved by) or connu de (known by).
What is the infinitive form of traduit?
The infinitive is traduire (to translate). French verbs ending in -uire, such as conduire (to drive) or produire (to produce), have irregular past participles ending in -uit.
How would the end of the sentence change if the translator were a woman?
