quicken

The word "quicken" has a vivid etymological journey beginning with the Old English adjective cwic, which primarily meant "alive" or "living." This sense survives in the archaic biological meaning "to come to life," as in a quickening fetus. The semantic shift from "alive" to "rapid, speedy" occurred in Middle English, likely influenced by the observable liveliness and brisk movement of living creatures. By adding the productive Old English verbal suffix -en, the word was transformed into a verb meaning "to make or become alive" or, following the later semantic evolution, "to make or become fast." Thus, the modern verb encapsulates both the ancient concept of imparting life and the more recent notion of accelerating motion.
