Today’s Parola del Giorno is the interjection, Su!, which means Come on! See the word used below in its context:
Mio padre si lamentava del fatto che la bolletta del gas fosse troppo alta. “Su!” dissi, “È normale durante i mesi invernali!”
My dad was complaining about the fact that the gas bill was perhaps too high. “Come on!” I said, “It is normal during the winter months!”
NB: Don’t forget that in Italian su can also be a preposition.
