beaver: [OE] Like bear, beaver appears to mean etymologically ‘brown animal’. Old English beofor or befor came from a prehistoric West and North Germanic *bebruz, which in turn went back to an Indo-European *bhebhrús, a derivative of the base *bhru- ‘brown’. Other words for ‘beaver’ from the same source include Czech bobr, Lithuanian bebrùs, and Latin fiber.
beaver (n.)
Old English beofor, befer (earlier bebr), from Proto-Germanic *bebruz (cognates: Old Saxon bibar, Old Norse bjorr, Middle Dutch and Dutch bever, Low German bever, Old High German bibar, German Biber), from PIE *bhebhrus, reduplication of root *bher- (3) "brown, bright" (cognates: Lithuanian bebrus, Czech bobr, Welsh befer; see bear (n.) for the likely reason for this). Gynecological sense ("female genitals, especially with a display of pubic hair") is 1927 British slang, transferred from earlier meaning "a bearded man" (1910), from the appearance of split beaver pelts.
