overtime

the word 'overtime' is a transparent compound formed from two native english elements. the prefix 'over', with its core sense of excess or surpassing, combines with the noun 'time', referring to a measured duration. this literal combination, meaning "time beyond," directly yields the modern legal and employment term. it first emerged in the early 19th century to describe hours worked in excess of the standard period, and later, by metonymy, came to denote the extra pay received for such work. the logic from its constituent parts to its contemporary meaning is exceptionally clear and direct.

Structure: over (above, beyond) + time (duration) 'over' is from old english 'ofer', meaning above or beyond. 'time' is from old english 'tīma', meaning a period or duration.
