means An official government document that proves your identity and nationality, allowing you to travel between countries.
from From the French passeport, literally 'pass through a port' — passer ('to pass') plus port ('a port' or 'gate'). The popular image is of ships and harbors, but in earlier usage 'port' often meant a town gate or fortified passage as much as a seaport: the document was your permission to pass through. It sailed into English in the 1400s–1500s and never left.
