Ultimate origin

Etymology

The animal is inherited from Middle English bever,[2][3][4][5] inherited from Old English beofor, also befor, earlier bebr,[6][7][8][9] from Proto-West Germanic *bebru,[10][9] from Proto-Germanic *bebruz,[7][8][11][12] from Proto-Indo-European *bʰébʰrus.[7][6] It is cognate with Old Saxon bibar, Old High German bibar (modern Biber), Middle Dutch bever, Dutch bever and Old Norse bjórr,[6][7][8][11] and outside Germanic with Latin fiber, Lithuanian bebrùs, Czech bobr and Welsh befer.[7][13][4][14] The Indo-European word is a reduplicated derivative of a root meaning "brown",[9][13][4] which also gave Sanskrit बभ्रु (babhrú, “reddish brown; mongoose”) and English brown,[9][6][3] so that the beaver, like the bear, is "the brown animal".[13][4][15]

Earliest recorded meaning

The animal: Barnhart finds bebr about 720 and beofor about 1000, in Ælfric's Glossary;[6] the OED's first quotation is from Ælfric's Grammar.[9] The Middle English Dictionary records beferes for the animal's testicles, castoreum, and bever heued, reddish brown.[5]

Semantic evolution

The beaver was hunted for its secretions and its fur,[7] and the fur gave most of the later senses: the fur itself from about 1394,[9] a beaver hat from Chaucer's "Flaundrish bevere hat" (about 1386),[9][16] a shade of brown from about 1400, in Sir Gawain,[9] and a hat simply called a beaver from 1528,[9][7] still used into the 19th century after hats came to be made of silk.[7][17] Later a felted cloth (1756) and a kind of glove (1816, in Jane Austen) were called beaver.[9] Its industry gave to work like a beaver (1741, originally American)[9] and the British verb to beaver away, to work hard, from 1946, which Merriam-Webster derives from the animal's proverbial energy.[9][3][18] Etymonline traces the slang sense "beard, bearded man" (1910) and the vulgar sense "female pubic area" (1927) to the animal or its pelts,[7] but the OED and Collins call their origin uncertain.[9][19] The youngest section of the Scouts, the Beavers, dates from 1975.[9]

Formation
Borrowing
First attested
1481–1490 Howard household books
Borrowed from
Old French baviere via Middle English
Ultimate origin
Old French bave

Etymology

The helmet guard is inherited from Middle English baviere,[3][9][4][15] borrowed from Old French baviere (“a child's bib”),[9][7][2][18] from bave (“saliva, slobber”),[9][7][3] or from the verb baver (“to slaver, dribble”).[18][20][19][4] Partridge and Klein take the word for saliva to be imitative.[15][4] It is cognate with baviera and babera.[9] Cotgrave's French–English dictionary (1611) glossed baviere as a bib and baviere d'un armet as the beaver of a helmet.[16]

Earliest recorded meaning

The lower part of the face-guard of a helmet: 1481–90, in the Howard household books;[9] Etymonline dates it to the early 15th century, and the Shorter Oxford to the late 15th.[7][18]

Semantic evolution

The name moved from a child's bib to the piece of armour that covered the lower face,[9][7][4] and was sometimes used of the whole face-guard or visor,[9][3] as in Shakespeare's Hamlet: "he wore his beaver up".[3][16] A figurative use is recorded from 1838, in Southey.[9] The Shorter Oxford marks the word obsolete except in historical use.[18]

  • 1481–90 – the lower face-guard of a helmet.[9]
  • 1838 – figurative use.[9]

Meanings

Noun

  1. (historical) A piece of armour protecting the lower part of the face.[3][18][9]
