A person who is a member of a crew; someone who works as part of a team on a ship, boat, or other vessel.
From crew (from Old French 'creue' meaning increase or levy of soldiers) plus '-er' agent suffix meaning one who. Used since the 16th century.
The word 'crew' originally meant an 'increase' in soldiers—it captured the military idea of people being added to form a fighting unit, which is why we still use it for teams!
