Indeed the name of the art form is just Italian for "work".

Also, a direct cognate with "operate", "operation", etc.

The Oracle corporation would like to speak to you about the name of their property management system.

(Also some Norwegians and a Web browser?)

the Romans, btw, knew two kinds of labour: labor, -is the laborious one (see ?), and opus, the achievement

Wow, TIL.
