英语词源
- level
-
level: [14] The Latin word for a ‘balance’ or ‘scales’ was libra (it has given English Libra the zodiacal sign [14] and also lies behind many terms for units of measurement, including litre and the abbreviation lb for ‘pound’). Its diminutive form was lībella, which denoted an ‘instrument for checking horizontality’, and hence a ‘horizontal line’. It passed into Old French as livel (which in modern French has become niveau ‘level’), and English took it over as level.
=> litre - level (n.)
- mid-14c., "tool to indicate a horizontal line," from Old French livel "a level" (13c.), ultimately from Latin libella "a balance, level," diminutive of libra "balance, scale, unit of weight," from PIE *lithra. Cognate Spanish nivel, Modern French niveau are from the same source but altered by dissimilation. Meaning "horizontality" is from c. 1400. Meaning "position as marked by a horizontal line" is from 1530s. Phrase on the level "fair, honest" is from 1872; earlier it meant "moderate, without great ambition" (1790).
- level (v.)
- mid-15c., "to make level," from level (n.). From c. 1600 as "to bring to a level;" 1958 as "to cease increasing." Meaning "to aim a gun" is late 15c. Slang sense of "tell the truth" is from 1920. To level up "to rise" is attested by 1863.

Garretson, "Professional Education," in "The Dental Cosmos," Philadelphia, 1865]
