weakly
UK: ˈwiːkli | US: ˈwiːkli
adv. in a weak or feeble manner
adj. (archaic) sickly or lacking strength
The word "weakly" combines the Old English root "wāc" (meaning "pliant" or "feeble") with the adverbial suffix "-ly," derived from Old English "-līce." Over time, "weak" evolved to describe physical or metaphorical lack of strength, while "-ly" standardized as a suffix to form adverbs. The archaic adjectival use ("weakly child") reflects an older pattern where "-ly" could also form adjectives, though this usage is now rare.

(Archaic) "A weakly infant required constant care."
