Etymology: In Scots, "buller" could mean to boil or seethe, and it could also mean to bellow or roar. Its ancestry is uncertain. The boiling sense is probably related to Old Norse "bulla" and Latin "bulliō," both meaning to boil, which may go back to a Proto-Indo-European root meaning swelling. The roaring sense likely came from a North Germanic source, as seen in Swedish "bullra" and Danish "buldre," both meaning to rumble, and ultimately from Proto-Germanic "bellaną," to roar. The noun has a simpler story: it is formed from "bull" with the suffix "-er."
