Pronunciation

  • UK: /ˈliː.və/[1]
  • US: /ˈlɛv.ɚ/, /ˈli.vɚ/[1]

Etymology

It is inherited from Middle English levour, also levere and lever,[2][3][4] borrowed from Anglo-Norman lever (“crowbar”), also leveor and levier,[5][6] from Old French leveor or levier, agent nouns from lever (“to raise”).[7][6][8][9] The OED notes that the French form with -eor is recorded for the tool only once (1487, as Middle French leveur), while the usual French word is levier, recorded from the 12th century and formed from the same verb with a different suffix;[7] Etymonline and the American Heritage Dictionary derive the English word from levier,[10][11] and Barnhart notes that leveor is also cited.[9] The French verb is from Latin levō (“to raise, lighten”),[10][11][12] from levis (“light in weight”),[10][11][9] from Proto-Indo-European *legʷʰ- (“not heavy, light”).[10][11] Klein lists among its cognates Ancient Greek ἐλαχύς (elakhús, “small”), Lithuanian leñgvas (“light”) and Old English lēoht (“light”), the source of light.[3]

Earliest recorded meaning

A bar of iron or wood used to prise up or dislodge something heavy or firmly fixed, a crowbar: 1297, in Robert of Gloucester's Chronicle,[7] where the besiegers bring laddren & leuours.[2] Barnhart and Etymonline date it to about 1300.[9][10]

Semantic evolution

In Middle English a levour was also a bar used as a weapon, a carrying pole and a straightedge,[2] and in Anglo-Norman it could be a cudgel;[5] the general sense of a bar or pole lasted from 1297 to 1613.[7] In 1648 J. Wilkins adopted the word in mechanics as the name of the simple machine of which the crowbar is an example,[7] and Johnson (1755) described it as the second of the mechanical powers.[13] From 1481 the word was used of a curved roof-beam,[7] a sense still found in 19th-century dialect in Northumberland and Durham.[14][7] Later uses named a starting-bar on a steam engine (1759), a surgical instrument (1846), the part that opens a breech-loading gun (1881) and, short for lever watch, a kind of watch (1865).[7] From 1862 it also meant any handle by which a machine is worked; from 1903 it was also a means of making something happen, as in to pull the lever.[7] The verb, to work with a lever, is recorded from 1856,[7][9][10] and in the transitive sense, to move with a lever, from 1876.[7][12]
