Etymology: "Pestilentially" is an adverb built in the most ordinary way: the adjective "pestilential" with the suffix "-ly" added to turn it into an adverb meaning "in a pestilential manner." The base adjective is itself rooted in "pestilence," a word for a deadly epidemic disease, which came into English through Old French from Latin "pestilentia," a noun derived from "pestis," meaning plague. The adjective "pestilential" was used long before the plague sense faded into metaphor. Over time, "pestilential" moved beyond literal disease to describe anything morally corrupt, tiresomely annoying, or noxious, and that broader sense is what the adverb carries. Something that behaves pestilentially acts like a plague on those around it, whether through spreading harm or simply through being a nuisance.
