traction

Etymology

It is borrowed from Medieval Latin tractiō (“a drawing, pulling”),^[2][3][4][5] in Middle English traccioun;^[3] the Shorter Oxford and the Oxford Dictionary of English allow that it may also be from French traction,^[6][7] which the OED records in Middle French once before 1365 and then from the 16th century.^[2] The Latin noun is formed on tractus, the past participle of trahō (“to draw, pull, drag”).^[2][8][9] In classical Latin tractiō was a grammatical term; in post-classical Latin it meant the drawing of blood (4th century), then from the 13th and 14th centuries the pull of a muscle, attraction, and the pulling of a broken or dislocated bone into place, as in Guy de Chauliac (1363).^[2] It is related to tract, tractor and attract.^[9][10]

Earliest recorded meaning

In surgery, pulling a dislocated or broken bone back into its proper position: ?a1425, in a translation of Guy de Chauliac's Grande Chirurgie.^[2][3] Barnhart, who did not have this example, dates the word to 1615.^[4]

Semantic evolution

In the 17th century the word was used of the pull of a muscle (1615), of drawing power or attraction (1608, in Middleton) and of pulling or drawing in general (1642).^[2] Johnson (1755) defined it as the act of drawing or the state of being drawn.^[11] The current senses date from the early 19th century:^[7] the drawing of vehicles or loads along a road or rail, from 1803,^[2][10] hence traction engine;^[10] the grip of a wheel on a surface, recorded by Barnhart from 1825 and by the OED from 1857;^[4][2] and the steady pull applied to a broken limb in hospital.^[6][12] The figurative sense, the support or interest that lets an idea or product make progress, as in gain traction, is recorded from 1942.^[2]
