Larboard
Larboard , noun
[Lar- is of uncertain origin, possibly the same as lower, that is, humbler in rank, because the starboard side is considered by mariners as higher in rank; compare Dutch laag low, akin to English low. See Board, n., 8.]
(Nautical) The left-hand side of a ship to one on board facing toward the bow; port; -- opposed to starboard.
Larboard is a nearly obsolete term, having been superseded by port to avoid liability of confusion with starboard, owing to similarity of sound.
Larboard , adjective
On or pertaining to the left-hand side of a vessel; port; as, the larboard quarter.
