means Someone who travels in a vehicle without driving or operating it, just along for the ride to a destination.

from From Old French 'passagier,' built on 'passage' (a crossing or journey), which traces to Latin 'passus,' meaning 'step' or 'pace' — the same root that gives us 'pass' and 'passage.' The extra 'n' crept in sometime later, likely by analogy with words like 'messenger,' another agent-noun that picked up a nasal sound it etymologically had no claim to. So a passenger is, at root, simply 'one who makes the passage' — the step-taker along for someone else's journey.
