  • fast (adj.) Old English fæst "firmly fixed, steadfast, constant; secure; enclosed, watertight; strong, fortified," probably from Proto-Germanic *fastu- "firm, fast" (source also of Old Frisian fest, Old Norse fastr, Dutch vast, German fest), from PIE root *past- "firm, solid" (source of Sanskrit pastyam "dwelling place").
  • fast (adv.) Old English fæste "firmly, securely; strictly;" also, perhaps, "speedily," from Proto-Germanic *fasto (source also of Old Saxon fasto, Old Frisian feste, Dutch vast, Old High German fasto, German fast "almost," but in earlier use "firmly, immovably, strongly, very"), from *fastu- (adj.) "firm, fast" (see fast (adj.)).
  • fast (n.) "act of fasting," late Old English fæsten "voluntary abstinence from food and drink or from certain kinds of food," especially, but not necessarily, as a religious duty; either from the verb in Old English or from Old Norse fasta "a fast, fasting, season for fasting," from a Proto-Germanic noun formed from the verbal root of fast (v.). In earlier Old English fæsten meant "fortress, cloister, enclosure, prison."
  • fast (v.) "abstain from food," Old English fæstan "to fast" (as a religious duty), also "to make firm; establish, confirm, pledge," from Proto-Germanic *fastan "to hold fast, observe abstinence" (source also of Old Frisian festia, Old High German fasten, German fasten, Old Norse fasta "abstain from food"), from the same root as fast (adj.).
