| 词根词缀 | 词源： 1. light (n.) "brightness," O.E. leht, earlier leoht, from W.Gmc. *leukhtam (cf. O.Fris. liacht, M.Du. lucht, Ger. Licht), from PIE *leuk- "light, brightness" (cf. Skt. rocate "shines;" Arm. lois "light," lusin "moon;" Gk. leukos "bright, shining, white;" L. lucere "to shine," lux "light," lucidus "clear;" O.C.S. luci "light;" Lith. laukas "pale;" Welsh llug "gleam, glimmer;" O.Ir. loche "lightning," luchair "brightness;" Hittite lukezi "is bright"). The -gh- was an Anglo-Fr. scribal attempt to render the O.E. hard -h- sound, which has since disappeared. The figurative spiritual sense was in O.E.; the sense of "mental illumination" is first recorded mid-15c. Meaning "something used for igniting" is from 1680s. The related verb is from O.E. lyhtan (cf. O.S. liohtian, Ger. leuchten, Goth. liuhtjan). 2. light (adj.) "not heavy," from O.E. leoht, from P.Gmc. *lingkhtaz (cf. O.N. lettr, Swed. lätt, O.Fris., M.Du. licht, Ger. leicht, Goth. leihts), from PIE base *le(n)gwh- "light, easy, agile, nimble" (cf. L. levis "light;" see lever).
