a broad and capacious bay comprehended between two promontories, and sometimes taking the name of a sea when it is very extensive; but particularly when it only communicates with the sea by means of a strait. Such are the Euxine or Black sea, otherwise called the Gulf of Constantinople; the Adriatic sea, called also the Gulf of Venice; the gulf of Sidra near Barbary; and the gulf of Lyons near France. All these gulfs are in the Mediterranean. There are, besides, the gulf of Mexico, the gulf of St Lawrence, and the gulf of California, which are in North America. There are also the gulf of Persia, otherwise called the Red sea, between Persia and Arabia; the gulf of Bengal in India; and the gulfs of Cochin-china and Kamtchatka, near the countries of the same name.

The word comes from the French golfe, and that from the Italian golfo, which signify the same. Some deduce these further from the Greek γαλάξις; which Guithart again derives from the Hebrew גָּבֵעַ. Du Cange derives them from the barbarous Latin gulfum, or gulfus, which signify the same thing.
