Sort of. The English spelling "pistachio" does come from (old) Italian pistacchio, but the word is much older than that. The Italian word came from the Latin pistacium, which they got from the Greeks, who called it pistákion, and they got that name (along with the nuts, themselves) from the Persians, who had been cultivating them since prehistoric times.
The Italian words for "very much" are "molto" or "assai."
