Other forms: navies
The navy is the part of a country's armed forces that fights at sea: the ships, the submarines, and the people who serve on them. You join the navy at eighteen, serve twenty years in the navy, and come out knowing how to tie things properly.
Navy is also a colour, short for navy blue, the very dark blue of a sailor's uniform, which is exactly where the colour got its name. A navy suit, navy tights, a wall painted navy. In Britain the service is the Royal Navy, capitalised because it is a name, while the navy in general stays lowercase. The adjective for anything to do with a navy is naval, as in a naval officer or a naval base, and it is worth keeping that apart from navel, which is your belly button.

Navy came through Middle English navye and Old French navie from Latin nāvigium, a fleet, built on nāvis, a boat. The root is the Proto-Indo-European word for ship, which also gave Greek naus and Sanskrit nāva. It pushed out the older English word for the same thing, sċiphere, which meant ship-army.
