braid: [OE] The ultimate source of braid was West and North Germanic *bregthan, whose underlying meaning was probably ‘make sudden jerky movements from side to side’. This was carried through into Old English bregdan, but had largely died out by the 16th century. However, ‘making swift side-to-side movements’ had early developed a special application to the intertwining of strands or threads, and it is this ‘plaiting’ sense which has survived. The Germanic base *bregth- was also the ultimate source of bridle, but the superficially similar embroider had a different origin.
