promontory
noun[L. promontorium; pro, forward, and mons, a mountain.]
In geography, a high point of land or rock, projecting into the sea beyond the line of the coast; a head land. It differs from a cape in denoting high land; a cape may be a similar projection of land high or low. Like one that stands upon promontory. If you drink tea on a promontory that overhangs the sea, it is preferable to an assembly.
