[edit] Usage notes

The most common plural of opus in English is opuses. Some people use the Latin plural, opera. Opi is fairly common in the field of classical music, though mostly in informal contexts. The use of any of these three pluralizations may result in the speaker being corrected, though opi above all should be avoided in formal contexts. Outside of music, the word opus sees particularly frequent use in the expression magnum opus.
