About This Root

From Latin opus (work) and operārī (to work). Highly productive: operate and operation (do work), cooperate (work together), opus (a musical work), and operetta (little work). Even maneuver/manoeuvre comes from Latin manu operare (work by hand). Cover and discover trace back through Old French from this root.
