KK: /ˈkruːnɛk/
A type of shirt or sweater that has a round neckline without a collar.
He wore a comfortable crewneck sweater on the chilly day.
Crewneck → The word is formed from "crew" (from the nautical term referring to a group of people working together on a ship) and "neck" (from Old English "necc", meaning the part of the body connecting the head to the torso). The term "crewneck" refers to a style of neckline that is round and close to the neck, often associated with casual clothing worn by a group or crew.
Think of a 'crew' working together and wearing a 'neck' style that is round and close to the body — that's what a crewneck is.
