英文词源
- accelerate
- accelerate: [16] Accelerate comes from Latin accelerāre, a compound verb formed from the intensive prefix ad- (ac- before /k/ sounds) and celerāre ‘hurry’. Celerāre, in turn, derived from the adjective celer ‘fast’ (which gave English celerity [15] and is ultimately related to hold).
- accelerate (v.)
- 1520s, from Latin acceleratus, past participle of accelerare "to hasten, quicken," from ad- "to" (see ad-) + celerare "hasten," from celer "swift" (see celerity). Related: Accelerated; accelerating.
