explain the meaning of the idiom, "it ain't over till the fat lady sings
user
this idiom is used to emphasize that something is not yet finished or concluded. it is often used in the context of sports or games and is equivalent to saying the game isn't over until it is over. it comes from the opera, where the "fat lady" is the lead soprano and her singing marks the end of the performance.
