bear (n.) Look up bear at Dictionary.com
Old English bera "bear," from Proto-Germanic *beron, literally "the brown (one)" (cognates: Old Norse björn, Middle Dutch bere, Dutch beer, Old High German bero, German Bär), from PIE *bher- (3) "bright, brown" (see brown (adj.)).

Greek arktos and Latin ursus retain the PIE root word for "bear" (*rtko; see Arctic), but it is believed to have been ritually replaced in the northern branches because of hunters' taboo on names of wild animals (compare the Irish equivalent "the good calf," Welsh "honey-pig," Lithuanian "the licker," Russian medved "honey-eater"). Others connect the Germanic word with Latin ferus "wild," as if it meant "the wild animal (par excellence) of the northern woods."

Symbolic of Russia since 1794. Used of uncouth persons since 1570s.
