c.1300, from Old French corde "rope, string, twist, cord," from Latin chorda "string of a musical instrument, cat-gut," from Greek khorde "string, catgut, chord, cord," from PIE root *ghere- "intestine" (see yarn). As a measure of wood (eight feet long, four feet high and wide) first recorded 1610s, so called because it was measured with a cord of rope.
cord or chord (kôrd)
A long ropelike bodily structure, such as a nerve or tendon.
frequently used in its proper sense, for fastening a tent (Ex. 35:18; 39:40), yoking animals to a cart (Isa. 5:18), binding prisoners (Judg. 15:13; Ps. 2:3; 129:4), and measuring ground (2 Sam. 8;2; Ps. 78:55). Figuratively, death is spoken of as the giving way of the tent-cord (Job 4:21. "Is not their tent-cord plucked up?" R.V.). To gird one's self with a cord was a token of sorrow and humiliation. To stretch a line over a city meant to level it with the ground (Lam. 2:8). The "cords of sin" are the consequences or fruits of sin (Prov. 5:22). A "threefold cord" is a symbol of union (Eccl. 4:12). The "cords of a man" (Hos. 11:4) means that men employ, in inducing each other, methods such as are suitable to men, and not "cords" such as oxen are led by. Isaiah (5:18) says, "Woe unto them that draw iniquity with cords of vanity, and sin as it were with a cart rope." This verse is thus given in the Chaldee paraphrase: "Woe to those who begin to sin by little and little, drawing sin by cords of vanity: these sins grow and increase till they are strong and are like a cart rope." This may be the true meaning. The wicked at first draw sin with a slender cord; but by-and-by their sins increase, and they are drawn after them by a cart rope. Henderson in his commentary says: "The meaning is that the persons described were not satisfied with ordinary modes of provoking the Deity, and the consequent ordinary approach of his vengeance, but, as it were, yoked themselves in the harness of iniquity, and, putting forth all their strength, drew down upon themselves, with accelerated speed, the load of punishment which their sins deserved."
unit of volume for measuring stacked firewood. A cord is generally equivalent to a stack 4 4 8 feet (128 cubic feet), and its principal subdivision is the cord foot, which measures 4 4 1 feet. A standard cord consists of sticks or pieces 4 feet long stacked in a 4 8-foot rick. A short cord is a 4 8-foot rick of pieces shorter than 4 feet, and a long cord is a similar rick of pieces longer than 4 feet. A face cord is a 4 8-foot stack of pieces 1 foot long. The cord was originally devised in order to measure firewood and was so named because a line, string, or cord was used to tie the wood into a bundle.
