quickly

The word 'quickly' is a straightforward combination of the adjective 'quick' and the adverbial suffix '-ly'. Its core lies in the Old English adjective cwic, which originally meant "alive" or "living." This ancient sense survives in the phrase "the quick and the dead." The semantic shift from "alive, lively" to "rapid, swift" is a natural metaphorical extension, as liveliness is often associated with brisk movement. The suffix '-ly', also of Old English origin, systematically converts adjectives into adverbs, specifying that an action is done in a 'quick' manner. Thus, the modern adverb 'quickly' literally means "in a lively or rapid manner," directly preserving the evolved sense of its Germanic root.

Structure: quick (fast) + ly (adverb suffix) quick: From Old English cwic (alive, living, animated), with the sense of "rapid" developing from the notion of being lively or vigorous. In this word, it functions as the adjectival root conveying the core meaning of speed. ly: From Old English -līce, an adverbial suffix used to form adverbs from adjectives. It indicates the manner or way in which an action is performed.
