Word Origin & History
brow
words for "eyelid," "eyelash," and "eyebrow" changed about maddeningly in O.E. and M.E. (and in all the W.Gmc. languages). Linguists have untangled the knot into two strands: 1. O.E. bræw (Anglian *brew) "eyelid," from P.Gmc. *bræwi- "blinker, twinkler" (related to Goth. brahw "twinkle, blink," in phrase in brahwa augins "in the twinkling of an eye"); the sense must have shifted before the earliest recorded O.E. usage from "eyelash" to "eyelid." 2. O.E. bru "eyelash," from P.Gmc. *brus "eyebrow," from PIE base *bhrus (cf. Skt. bhrus "eyebrow," Gk. ophrys, O.C.S. bruvi, Lith. bruvis "brow," O.Ir. bru "edge"). The sense must have been transferred in O.E. at an early date from "eyebrow" to "eyelash." Lacking a distinctive word for it, the Anglo-Saxons called an eyebrow ofer-bru, and in early M.E. they were known as uvere breyhes or briges aboue þe eiges. By c.1200, everything had moved "up." Bru/brouw (from bræw) became "eyelid;" and brew/breow (from O.E. bru) became "eyebrow." It remained the word for "eyebrow" in Scot. and northern Eng., where it naturally evolved into colloquial bree. In southern Eng., however, M.E. bru/brouw took over the sense of "eyebrows," in the form brues, and yielded the usual modern form of the word. To make matters worse, if possible, some southern writers 15c.-17c. used bree for "eyelashes," in what OED calls "a curious reversion to what had been the original OE. sense of bru." By 1535, brow had been given an extended sense of "forehead," especially with ref. to movements and expressions that showed emotion or attitude. Browbeat "to bully" is first recorded 1581, originally "to bear down with stern or arrogant looks." When my son was learning to talk, he called them eyebrowns, but it has no connection to brown; the -n- in the O.N. (brun) and Ger. (braune) forms of the word are from a gen. pl. inflection.
