Cape
CAPE, noun
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 neck-piece of a cloke or coat.
