- rapid[rapid 词源字典]
- rapid:  Like rape and rapture, rapid comes ultimately from Latin rapere ‘seize by force’. From this was derived the adjective rapidus, which originally denoted ‘carrying off by force’. The notion of ‘swiftness’ soon became incorporated into the meaning, however, and although the Latin adjective retained its original connotations of violence (it suggested ‘impetuous speed’ or ‘haste’), by the time it reached English it had simply become synonymous with ‘quick’.
