This adjective identifies something as belonging to or originating from Adramyttium, a seaport in the Roman province of Asia (modern-day Turkey). Luke uses it in Acts 27:2 to describe the ship Paul boarded at Caesarea—"a ship of Adramyttium." The term functions as a geographical identifier showing the vessel's home port. Adramyttium was located in Mysia on the northwest coast of Asia Minor, and ships from this port would typically sail along the Asian coastline, which fits Luke's narrative of Paul's journey toward Rome.
