Boatneck → The word is formed from "boat" (from Old English *bāt*, meaning a small vessel for traveling on water) and "neck" (from Old English *necca*, meaning the part of the body connecting the head to the torso). The term "boatneck" refers to a style of neckline that resembles the shape of a boat, wide and open at the shoulders.
Imagine a neckline that is as wide and open as a boat — that's why it's called a boatneck.
