英语词汇supersonic的起源、历史背景-英语词源词典

词汇	supersonic
词源	supersonic adj. 1919, "of or having to do with sound waves beyond the limit of human hearing," from super- + sonic. Attested from 1934 in sense of "exceeding the speed of sound" (especially as a measure of aircraft speed), leaving the original sense to ultrasonic (1923). Entries linking to supersonic super- word-forming element meaning "above, over, beyond," from Latin super (adverb and preposition) "above, over, on the top (of), beyond, besides, in addition to," from (s)uper-, variant form of PIE root uper "over." In English words from Old French, it appears as sur-. The primary sense seems to have shifted over time from usually meaning "beyond" to usually meaning "very much," which can be contradictory. E.g. supersexual, which is attested from 1895 as "transcending sexuality," from 1968 as "very sexual." sonic adj. "done by means of sound waves," 1923, from Latin sonus "sound" (from PIE root swen- "to sound") + -ic. Sonic boom* "shock wave from an aircraft exceeding the speed of sound" is attested from 1952. super-sonic (adj.)ultrasonic (adj.)subsonic (adj.) updated on September 03, 2012
