confidence v. confidenza
In English, we use confidence to mean trust or faith in a thing or person, as the first entry in the American Heritage dictionary. However a word that appears similar in Italian, confidenza, means intimacy in English so beware of misusing it. Use the Italian, fiducia, to better translate the correct idea.
Eng) We have confidence in our coach.
It) Abbiamo fiducia nel nostro allenatore.
