Questions & Answers about L'illusion que nous avons vu créer s'est évaporée en l'espace d'une seconde.
Does en l'espace d' mean the same thing as just using en here?
Why is it vu and not vue, since it refers to the feminine noun L'illusion?
This is a special rule for perception verbs like voir followed by an infinitive. The past participle only adds agreement for the preceding direct object (the illusion) if that object is the one doing the action of the infinitive. Since the illusion isn't doing the creating (it is being created), vu stays invariable.
Why does the French use the active verb créer to mean 'being created'?
In French, when an infinitive directly follows a verb of perception like voir or entendre, it stays active even if it translates to a passive idea in English. You can think of it literally as 'the illusion that we saw [someone] create'.
Why does évaporée have an extra -e at the end?
It is the passé composé of the reflexive verb s'évaporer. Reflexive verbs use être as their auxiliary, and their past participle must agree with the preceding direct object. Here, the reflexive pronoun s' acts as the direct object referring back to L'illusion (feminine singular), so we add an -e.
