Etymology

Origin of opus

1695–1705; < Latin: work, labor, a work

Explanation

An opus is a created work, usually musical in nature. The composer's greatest opus was inspired by the blooming of the spring flowers. While an opus is a piece of work, usually musical, the best way to remember it is to know that the preferred plural of opus is opera which everyone associates with music. You can also say opuses for the plural if you want, but how is that going to help you remember anything? A common usage of opus is with the term magnum opus which refers to one’s greatest work, musical or otherwise.
