What does "bay" mean?

Bay: (Geol.) An inlet of the sea, usually smaller than a gulf, but of the same general character. Note: The name is not used with much precision, and is often applied to large tracts of water, around which the land forms a curve; as, Hudson's Bay. The name is not restricted to tracts of water with a narrow entrance, but is used foe any recess or inlet between capes or headlands; as, the Bay of Biscay.
