Word Origin & History

thumb
O.E. þuma, from W.Gmc. *thumon- (cf. O.Fris. thuma, O.S., O.H.G. thumo, Ger. Daumen, Du. duim "thumb," O.N. þumall "thumb of a glove"), lit. "the stout or thick (finger)," from PIE *tum- "swell" (cf. L. tumere "to swell," tumidus "swollen;" Avestan tuma "fat;" see
EXPAND
thigh). For spelling with -b (attested from c.1290), see limb. The verb meaning "to go through" (especially of printed material) is first found 1930, though the related sense of "soil or wear by handling" dates from 1644. Verb meaning "to hitchhike" is 1939, originally the thumb pointed in the direction one wished to travel. Thumbnail sketch (1852) so called for its smallness. To be under (someone's) thumb "be totally controlled by that person" is recorded from 1586. Thumbs up (1887) and thumbs down (1906) were said to be from expressions of approval or the opposite in ancient amphitheaters, especially gladiator shows, where the gesture decided whether a defeated combatant was spared or slain. But the Roman gesture was merely one of hiding the thumb in the hand or extending it. Perhaps the modern gesture is from the usual coachmen's way of greeting while the hands are occupied with the reins.

Idioms & Phrases

thumbs up

An expression of approval or hopefulness, as in The town said thumbs up on building the elderly housing project. The antonym thumbs down indicates disapproval or rejection, as in Mother gave us thumbs down on serving beer at our party. Alluding to crowd signals used in Roman amphitheaters, these idioms were first recorded in English about 1600. In ancient times the meaning of the gestures was opposite that of today. Thumbs down indicated approval; thumbs up, rejection. Exactly when the reversal occurred is not known, but the present conventions were established by the early 1900s.
