stivy

A British dialect word describing the uncomfortable stuffiness of a room that's too warm, badly ventilated, or crammed with people — that heavy, airless feeling where the atmosphere feels almost solid. Stivy is the exact word for the sensation of walking into a pub or cottage where someone's had the fire going all day and no window open. It's particularly common in northern English dialects and captures a very specific kind of domestic discomfort that 'stuffy' almost gets at but doesn't quite nail.
