Etymology

The word "quickly" derives from the Old English "cwiclice," combining "cwic" (alive, lively, fast) and the adverbial suffix "-lice" (modern "-ly"). Originally, "quick" referred to being alive or vigorous (as in "the quick and the dead"), but its meaning narrowed to emphasize speed by the 13th century. The suffix "-ly" systematically converts adjectives into adverbs in English, preserving the root's spelling while altering its grammatical function.
