Linguists aren't sure of the meaning of the word "Pequot", although the currently most common theory is that it means "the men of the swamp".

One of the important symbols is the Pequod.
The Pequod is in the hunt for Moby-Dick, an effort which is destined to fail. The ship's very name depicts failure, as it is named for an Indian tribe in Massachusetts that did not survive after the arrival of the white men. Painted a morbid black and adorned with whale bones and teeth, the ship contains images of death everywhere the sailors look. It is decorated like a coffin, and that is what it eventually becomes.

Pequot is an Algonquian word, the meaning of which is in dispute among language specialists. Considerable scholarship pertaining to the Pequot claims that the name came from Pequttoog, meaning, "the destroyers," or "the men of the swamp". This relies on speculations of an early twentieth century authority on Algonquian languages. However, Frank Speck, a leading early 20th century specialist of Pequot-Mohegan, had doubts. He believed that another term meaning "the shallowness of a body of water" seemed much more plausible, given their territory along the coast of Long Island Sound.
