词源

From Middle English swift, from Old English swift (“swift; quick”), from Proto-Germanic *swiftaz (“swift; quick”), from Proto-Indo-European *(s)weyp- (“to twist; wind around”). Cognate with Icelandic svipta (“to pull quickly”), Old English swīfan (“to revolve, sweep, wend, intervene”). More at swivel.
