A cabin is a small, simple house, often made of wood and located in a rural or forest area. It can also mean a private room on a ship or airplane.
From Old French 'cabane' meaning 'hut, small house,' from Late Latin 'capanna' with the same meaning. It originally referred to simple shelters and then extended to small enclosed spaces on ships. Modern use keeps both the rustic-house and enclosed-room senses.
The same root idea—'a small enclosed shelter'—covers everything from a log cabin in the woods to a cabin on a cruise ship. Airplane 'cabin pressure' reminds you that the passenger area is basically a sealed, artificial hut in the sky. The word shows how humans keep reinventing the same basic idea: a small safe box to live or travel in.
