英文詞源
- energy
- energy: [16] Energy comes ultimately from Greek érgon ‘deed, work’. This was a descendant of Indo-European *wergon, which also produced English work, liturgy, organ, and orgy. Addition of the prefix en- ‘a(chǎn)t’ produced the adjective energés or energōs ‘a(chǎn)t work’, hence ‘a(chǎn)ctive’, which Aristotle used in his Rhetoric as the basis of a noun enérgeia, signifying a metaphor which conjured up an image of something moving or being active. This later came to mean ‘forceful expression’, or more broadly still ‘a(chǎn)ctivity, operation’. English acquired the word via late Latin energīa.
=> liturgy, organ, orgy, work - energy (n.)
- 1590s, "force of expression," from Middle French énergie (16c.), from Late Latin energia, from Greek energeia "activity, action, operation," from energos "active, working," from en "at" (see en- (2)) + ergon "work, that which is wrought; business; action" (see organ).
Used by Aristotle with a sense of "actuality, reality, existence" (opposed to "potential") but this was misunderstood in Late Latin and afterward as "force of expression," as the power which calls up realistic mental pictures. Broader meaning of "power" in English is first recorded 1660s. Scientific use is from 1807. Energy crisis first attested 1970.
