What does companionway mean?
A companionway is a stairway or ladder that connects two decks of a ship, along with the hatchway or opening through which it passes. The term is distinctly nautical, appearing most often in descriptions of sailing vessels, yachts, and maritime fiction. Aboard a boat, the companionway serves as the principal link between the open deck and the interior cabins below; it is often fitted with sliding boards or a washboard system that can seal the opening against heavy weather. In everyday use, the word signals familiarity with life at sea — a sailor might say she 'came up the companionway' onto deck or 'dropped down' into the cabin below. Though technical in flavor, the word is evocative and widely recognized among anyone who has spent time aboard a vessel. Its singular form is standard, and it remains an established part of English nautical vocabulary.

Etymology of companionway
The term derives from the nautical sense of 'companion', which referred to the space beneath the quarterdeck where officers took their meals — itself borrowed from French 'compagnon', meaning messmate or partner, ultimately from Latin 'companionem' ('one who eats bread with another'). Over time, the word came to denote the stairway and hatch leading down into this area. It has been in use since at least the 18th century as part of standard maritime vocabulary.
