the adverb "witheringly" is built upon the verb "wither," whose origins are somewhat obscure but likely rooted in old english or old norse concepts of exposure and resistance. the core sense of "wither" evolved from meaning "to weather, to dry out" to the modern sense of shriveling or losing vitality, both literally for plants and figuratively for human spirit or social standing. the addition of the "-ing" suffix transforms the action into a descriptive quality, and the final "-ly" suffix further converts it into an adverb. thus, the word's literal journey from describing physical decay culminates in its primary modern abstract use: to describe a manner of speech or look so scornful it can metaphorically cause its target to shrivel.
