Question

How do u conjugate french verbs in the conditionnel anterieur and futur anterieur?

Answer 1

Futur antérieur :

J'aurai fini le dîner à 17h=I will have finished dinner at 5 p.m

Je serai partie demain=I will have left tomorrow

So, it's "to have" or "to be" in future (you have to know which verbs take the auxiliary to be in French)+past participle. It works the same as passé composé but the auxiliary in in future tense.

Le conditionnel antérieur also works the same way as passé composé, but the auxiliary is conjugated in conditionnal.

J'aurais mangé si je n'avais pas été malade = I would have eaten if I hadn't been ill.

Je serais partie si tu m'avais donné les clefs de la voiture=I would have left if you had given me the keys of the car.
