is also the plural of opus
in Latin. This meaning has become archaic
, as it would lead to confusion with the aforementioned art form, but it's an interesting bit of music trivia
, and might help you with a crossword puzzle
some day. In English the usual plural of 'opus' is 'opuses', and in Italian 'opere', since 'opera' has become a singular noun there as well.
So now if you've written a few songs you can tell people you've "composed several opera."
