braid v.
"plait, knit, weave, twist together," c. 1200, breidan, from Old English bregdan "move quickly, pull, shake, swing, throw (in wrestling), draw (a sword); bend, weave, knit, join together; change color, vary; scheme, feign, pretend" (class III strong verb, past tense brægd, past participle brogden), from Proto-Germanic *bregdanan "make sudden jerky movements from side to side" (compare Old Norse bregða "brandish, turn about, move quickly; braid;" Old Saxon bregdan "weave, braid;" Old Frisian brida "twitch (the eye);" Dutch breien "knit;" Old High German brettan "draw, weave, braid"), perhaps from a PIE root *bhrek- (compare Sanskrit bhurati "moves quickly," Lithuanian bruzdùs "fast"), but there are phonetic difficulties. In English the verb survives only in the narrow definition of "plait hair." Related: Braided; braiding.
