    Note

    A word that began on the body. Middle English coste meant a rib, a flank or the side of a building, and also a shore, a district, even a division of the heavens. The seaside meaning is the one that lasted. It names the land along the water, so a coast is rocky or flat and runs past places: the coast of Maine, the southern coast.
