Root Breakdown

Root-derived
opuswork, labor, opus
=opus

opus is the Latin word at the heart of this whole family — it simply means 'a work.' English borrowed it unchanged for the 'created work' branch: a numbered composition (Opus 27) or, in 'magnum opus,' a creator's greatest single work.

Root oper still carries 16 more words

Why It Means This

opus is the noun ancestor of operate, cooperate, and the rest — but while those words developed the 'working' sense, opus kept the original 'finished work' sense. That's why it sits in the artistic branch: a composer's Opus 9 is the ninth work they produced. The plural is the Latin 'opera' — which is also where the musical 'opera' comes from.
