This is the 86th most frequent Italian word.
visto
"Visto" in Italian means "seen" or "visa" depending on the context.
Here, "visto" is used as a conjunction meaning "since" or "given that"; it provides a reason or cause for the main assertion.
Visto che piove, rimango a casa.
Since it's raining, I'm staying home.
"Visto" is again the past participle of "vedere," but here it is used to form a question in the passato prossimo tense regarding someone's recent actions.
L’hai visto recentemente?
Have you seen him recently?
In this sentence, "visto" is the past participle of the verb "vedere" (to see) and is used to form the passato prossimo tense together with the auxiliary verb "avere".
