What is 'Do you want' when translated from English to Italian?

Answer 1

Vuoi? is an Italian equivalent of the English phrase "Do you want?"

Specifically, the word functions as the present indicative of the present infinitive volere in the second person informal singular. The appropriate subject pronoun tu("[informal singular] you") -- which may be included only for clarification or emphasis -- is unnecessary since the verb ending identifies the listener's person. The pronunciation will be "vwoy"* in Italian.

*The sound is similar to that in the English noun "toy."

Answer 2

Che vuoi, Lei che cosa vuole? and Cosa volete? are Italian equivalents of the English phrase "What do you want?" Context makes clear whether a formal (case 2) or informal "you" (example 1) or two or more "you all" (example 3) suits. The respective pronunciation will be "key vwoy," "ley key KO-sa VWO-ley" and "KO-sa vo-LEY-tey" in Pisan Italian.
