Origins

Meanings 1–2, 4–5, 7, 12–13

Middle English had it as labor or labour, taken from Old French labor (labeur in modern French) and from Latin labor, the word the French came from.

Meanings 6, 8–11

From Middle English labouren, from Old French laborer, from Latin laborare ("to labour, strive, exert oneself, suffer; to work out"), from labor ("toil, work, exertion"), perhaps remotely related to robur ("strength"). It replaced the native English word swink ("toil").
