Though the word derives from French, encore was traditionally not used this way in French, nor ancora in Italian.French speakers commonly use instead either une autre (‘another’), un rappel (‘a return, curtain call’) or the Latin bis (‘second time’) in the same circumstances. Italians also use bis and, formerly, da capo (‘from the beginning’).

But how do Greeks ask for more? I found this, have to double check, but it sounds logical to me.

encore interj (another song) μπιζ επιφ.  /  κι άλλο επιφ. / άλλη μια φορά έκφρ.

encore n (return that night) μπιζάρισμα ουσ. ουδ.

encore vtr (to call for an encore) μπιζάρω ρ.αμ.
