Etymology

Origin of gulf

1300–50; Middle English go ( u ) lf < Old French golfe < Italian golfo < Late Greek kólphos, Greek kólpos bosom, lap, bay

Explanation

Deep, wide and often filled with water, a gulf is any vast and seemingly unbridgeable area. You've probably heard of the Gulf of Mexico, that large body of water that's partly surrounded by land. But a gulf doesn't have to be all about the ocean. If two people have vastly different cultures or opinions, you could say that there's a gulf between them — a large divide that neither side is willing or able to cross.
