- twice:  Twice was formed from Old English twige ‘twice’ (itself based on twi-, the combining form of two) and the genitive ending -s, which was used for creating adverbs, such as always, nowadays, once, thrice, etc.
- twice (adv.)
- late Old English twies, from Old English twiga, twigea "two times," from Proto-Germanic *twiyes (cognates: Old Frisian twia, Old Saxon tuuio), from PIE *dwis-, adverbial form of *dwo- "two" (see two). Spelling with -ce reflects the voiceless pronunciation.
