Conjugation drill for the 17 Dr & Mrs Vandertramp verbs — every one of these takes être as its auxiliary, which forces the past participle to agree with the subject in gender and number. Conditionnel passé describes something that would have happened, typically under some condition that didn't actually occur (often paired with a "si + plus-que-parfait" clause) — the auxiliary here is être conjugated in the conditionnel présent (serais/serais/serait/serions/seriez/seraient), not the présent (passé composé), the imparfait (plus-que-parfait), or the futur simple (futur antérieur).
