Origin

From earlier twise, from Middle English twies, twiȝes, from Old English twīġes (“twice”), from twīwa, twīġa ("twice"; whence Middle English twie (“twice”)) + -es (adverbial genitive ending). Related to Saterland Frisian twäie (“twice”), Middle Low German twiges, twies (“twice”), Middle High German zwies (“twice”). Equivalent to twi- (“(in) two; both”) + -ce. Similarly constructed to the prefixes bis- and dis-, borrowed from Indo-European cognates.
