Davy Jones' Locker, also Davy Jones's Locker, is an idiom for the bottom of the sea: the state of death among drowned sailors and shipwrecks.[2] It is used as a euphemism for drowning or shipwrecks which the sailor(s)'s and/or ship(s)'s remains are consigned to the bottom of the sea (to be sent to Davy Jones' Locker).[3]
The origins of the name of Davy Jones, the sailor's devil,[2] are unclear, with a 19th-century dictionary tracing Davy Jones to a "ghost of Jonah".[4] Other explanations of this nautical superstition have been put forth, including an incompetent sailor or a pub owner who kidnapped sailors.
