Etymology: "Stuffily" is simply "stuffy" with the adverbial ending "-ly" added, so the interesting history lies in the root. "Stuffy" comes from "stuff" with the suffix "-y" attached, and the root traces back through Proto-Germanic to Proto-Indo-European "*leyg-", a root that also gave rise to words for things enclosed or closed in. The "-ly" ending descends from an old Germanic word meaning "body" or "form", which over time became a suffix meaning "in the manner of" or "having the quality of". The word as a whole therefore describes a manner that is literally "in the way of something stuffed": crowded, airless, and closed in. That physical sense of a stifling room gradually carried over to people and their behaviour, so that a stuffy person or manner came to suggest a lack of fresh air, both literal and social.
