Lash.
1. (Weaving.) A thong formed of the combined ends of the cords by which a certain set of yarns are raised in the process of weaving Brussels carpet. Each yarn (termed an end) passes through an eye (the mail), to which is attached a cord passing over a pulley above the frame of the loom. The cords required to raise to the surface a certain set of yarns, required for one row in the pattern, are bound together into a lash, so as to be operated by a single pull. See Brussels carpet.
2. The thong or braided cord of a whip.
