bear: [OE] The two English words bear ‘carry’ and bear the animal come from completely different sources. The verb, Old English beran, goes back via Germanic *ber- to Indo-European *bher-, which already contained the two central meaning elements that have remained with its offspring ever since, ‘carry’ and ‘give birth’. It is the source of a very large number of words in the Indo-European languages, including both Germanic (German gebären ‘give birth’, Swedish börd ‘birth’) and non-Germanic (Latin ferre and Greek phérein ‘bear’, source of English fertile and amphora [17], and Russian brat ‘seize’).

And a very large number of other English words are related to it: on the ‘carrying’ side, barrow, berth, bier, burden, and possibly brim; and on the ‘giving birth’ side, birth itself and bairn ‘child’ [16]. Borne and born come from boren, the Old English past participle of bear; the distinction in usage between the two (borne for ‘carried’, born for ‘given birth’) arose in the early 17th century.

Etymologically, the bear is a ‘brown animal’. Old English bera came from West Germanic *bero (whence also German bär and Dutch beer), which may in turn go back to Indo- European *bheros, related to English brown. The poetic name for the bear, bruin [17], follows the same semantic pattern (it comes from Dutch bruin ‘brown’), and beaver means etymologically ‘brown animal’ too.

bear (n.)youdaoicibaDictYouDict
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. Stock market meaning "speculator for a fall" is 1709 shortening of bearskin jobber (from the proverb sell the bearskin before one has caught the bear); i.e. "one who sells stock for future delivery, expecting that meanwhile prices will fall."
