CAPE, n. [Sp. and Port. cabo; It. capo; Fr. cap; D. kaap; Dan. kap; L. caput; Gr. κεφαλη; Sans. cabala, head. It signifies end, furthest point, from extending, shooting.]

1. A head-land; properly the head, point or termination of a neck of land, extending some distance into the sea, beyond the common shore; and hence the name is applied to the neck of land itself, indefinitely, as in Cape Cod, Cape Horn, Cape of Good Hope. It differs from a promontory in this, that it may be high or low land; but a promontory is a high bold termination of a neck of land.
2. The part of a garment hanging from the neck behind and over the shoulders.
