Questions & Answers about Abbiamo cominciato la fase operativa.
Why do we use avere (abbiamo) as the helper verb here instead of essere?
Because in this sentence, cominciare (to begin) acts on a direct object: la fase operativa (the operational phase). When verbs like cominciare, iniziare, and finire are used transitively (meaning someone is starting or finishing something), they take avere. If the subject itself was starting—for example, "The phase has begun"—you would use essere and say La fase è cominciata.
Since la fase is feminine, why doesn't the past participle change to cominciata?
Because the auxiliary verb is avere. When you use avere in the passato prossimo, the past participle (cominciato) ends in -o and does not agree with the noun that comes after it. It would only change to cominciata if we were using essere.
Could I use iniziare instead of cominciare in this sentence?
