\Lar"board`\, n. [Lar- is of uncertain origin, possibly
the same as lower, i. e., humbler in rank, because the
starboard side is considered by mariners as higher in rank;
cf. D. laag low, akin to E. low. See {Board}, n., 8.] (Naut.)
The left-hand side of a ship to one on board facing toward
the bow; port; -- opposed to {starboard}.
Note: Larboard is a nearly obsolete term, having been
      superseded by port to avoid liability of confusion with
      starboard, owing to similarity of sound.

\Lar"board`\, a.
On or pertaining to the left-hand side of a vessel; port; as,
the larboard quarter.
