Fuoco means fire in Italian. Fuoco nel fuoco = fire in the fire, literally. un fuoco nel fuoco = a fire inside another fire I guess you are referring to an Eros Ramazzotti's song title. It is an uncommon saying, though. It means that love is consuming him more than a fire :) In a figurative sense like it was burning him twice. Now I want to know how you would say that in German LOL
