Many (all that I looked) English-Italian dictionaries give a transaltion for "a hat" as "capello". However, looking for this word the other way around never shows "hat" as one of the translations of the word "capello". Two Italian dictionaries I have looked in also don't mention any kind of head covering as a meaning of "capello" (one, two).
Does "capello" ever mean any kind of head covering at all? If yes, if this a special kind of hat?
