Word Origin & History
gulf
c.1300, from O.Fr. golfe "a gulf, whirlpool," from It. golfo "a gulf, a bay," from L.L. colfos, from Gk. kolpos "bay, gulf," earlier "trough between waves, fold of a garment," originally "bosom," the common notion being "curved shape," from PIE *qwelp- "to vault" (cf. O.E. hwealf, a-hwielfan "to overwhelm"). Latin sinus underwent the same development, being used first for "bosom," later for "gulf." Replaced O.E. sæ-earm. Figurative sense of "a wide interval" is from 1557. The Gulf Stream (1775) takes its name from the Gulf of Mexico.
