cabane

Cabin comes from Old French cabane (hut, cottage), from Provençal cabana, from Late Latin capanna (hut), possibly of pre-Roman Celtic origin. The word named a small, simple shelter. Applied to ships, it initially described a temporary wooden structure erected on deck to shelter the captain or passengers. Below-deck cabins came later, as ship design evolved to enclose living spaces within the hull.

Medieval ship cabins were afterthoughts. The captain's cabin, located at the stern, was the largest and often the only private space on the ship. Officers shared a smaller space. Sailors slept on deck or in the hold, with no cabin at all. The word 'cabin' implied privacy and rank — not everyone got one. The hierarchy of space on a ship was absolute, and the cabin was its most visible expression.

The passenger cabin transformed ocean travel in the nineteenth century. Steamship companies divided their ships into classes: first class had spacious cabins with portholes, second class had smaller ones, and steerage had open dormitories. The Titanic's first-class cabins included private promenades, fireplaces, and sitting rooms. Steerage passengers shared bunks in the hull. The word 'cabin' covered both, technically. Practically, they were different worlds.

The airline cabin borrowed the word in the early twentieth century. The enclosed passenger space of an aircraft is called a cabin — a usage that would puzzle a medieval sailor. A cabin was a hut. Then it was a room on a ship. Then it was the inside of an airplane. The word followed enclosed spaces from the ground to the sea to the air.
