Questions & Answers about A proposito, hai realizzato il tuo sogno?
How does a proposito work here?
On its own at the start of a sentence, a proposito means "by the way." You will also often see it used with the preposition di (a proposito di...) when you want to say "speaking of..." or "concerning..." a specific topic.
Can I use realizzato to say "I realized I left my keys at home"?
Why does realizzare use avere (hai) as its helper verb instead of essere?
Realizzare is a transitive verb here, meaning it acts directly on an object (What are you achieving? The dream). Verbs that can take a direct object always use avere as their auxiliary verb in past tenses like the passato prossimo.
Why is there an il before tuo sogno? Doesn't tuo already mean "your"?
