starboard: [OE] Starboard is etymologically ‘steer-board’. The word originated as an Old English compound formed from stēor ‘paddle, rudder’ (a relative of the verb steer) and bord ‘board’. The early Germanic peoples propelled and steered their boats by means of a paddle on the right-hand side of the vessel – hence the use of starboard as the nautical equivalent of right. => steer[starboard etymology, starboard origin, 英语词源]
