From Middle English quikenen (“to become alive again after dying; to raise (someone) from the dead; to regain consciousness or strength; to give vitality, revive; to regain validity; to nourish; to spare (the life of someone or something); to ignite; to illuminate; of events: to happen more quickly; of clouds: to form”) [and other forms], from quiken (“to come to life; to become alive again after dying; to give or regain vitality, revive; of a seed: to germinate, grow; to arouse (anger); to inspire; to reinforce, strengthen; to make (a substance) alchemically active; to nourish, sustain; to sharpen; to ignite; to illuminate; of news: to spread”) + -en (suffix forming the infinitive forms of verbs). Quiken is derived from Old English cwician (“to bring to life, vivify; to come to life, become living; to quicken”), from cwic (“alive, live, living; mentally agile; intelligent, keen”) (ultimately from Proto-Germanic *kwikwaz (“alive; lively; quick”) and Proto-Indo-European *gʷeyh₃- (“to live”)) + -ian (suffix forming verbs from adjectives and nouns). The English word may be analysed as quick (“moving with swiftness; occurring in a short time; (archaic) alive, living; (archaic) pregnant”) + -en (suffix attached to some adjectives forming transitive verbs meaning ‘to make [adjective]’). Cognates * Danish kvikne (“to quicken, revive”) * Icelandic kvikna (“to ignite; to turn on”) * Swedish kvickna (“to revive”)
