>Also fermentum, etc., of course. Skt. bHaru- m. 'sea' and Celtic *bervo: 'seethe, boil' also belong here. We should probably reconstruct a metathetic root like *bHerh1-/*bHreh1-, approx. 'splash, foam, boil', with derivatives such as *bHerh1-u-s 'troubled water', *bHreh1-wr 'spring, well'. I am not sure how to analyse the Germanic "burn-/brun-" words (*brunnaz, *brunno:n-); they look as if they could be derivatives of *bHrh1-un-.Pokorny suggests an r/n-heteroclitic *bhréh1-wr, bhrh1-un-.
