What is a Gulf?

A gulf is a body of water that is connected to a sea or ocean. There will be land partially surrounding the water, but it is larger than a bay. A gulf is often a long or large landlocked part of the sea that opens at a strait. In truth though, there are no rules for the naming of waters, or there were not when most were named. The word Gulf may just be what the person who discovered it decided it should be.
