Questions & Answers about Ho visto il cameriere che portava il vassoio.
Why do we translate 'carrying' with che portava instead of a gerund?
English naturally uses an -ing verb after verbs of perception like seeing or hearing. Italian, however, often uses a 'pseudo-relative' clause to express this: the perception verb (Ho visto), the object (il cameriere), che, and an imperfect verb (portava). This highlights that you witnessed an action already in progress.
Could I use the infinitive here, like Ho visto il cameriere portare il vassoio?
Yes, absolutely. Using the infinitive (portare) is another perfectly correct way to translate 'I saw the waiter carrying the tray.' However, the che plus imperfect structure specifically emphasizes the ongoing, continuous nature of the action while you were watching.
What would happen if I translated 'carrying' literally and used the gerund portando?
Why does the pseudo-relative clause use the imperfect tense (portava) instead of the passato prossimo?
The imperfect tense is used for ongoing, unfinished actions in the past. Since you saw the waiter right in the middle of the act of carrying the tray, portava acts like 'was carrying' to describe the scene you observed. Using a completed past tense here wouldn't capture that 'in progress' meaning.
