পাসপোর্ট শব্দটির উৎপত্তি কথা থেকে ?
Etymological sources show that the term "passport" is from a medieval document that was required in order to pass through the gate (or "porte") of a city wall or to pass through a territory. In medieval Europe, such documents were issued to foreign travelers by local authorities (as opposed to local citizens, as is the modern practice) and generally contained a list of towns and cities the document holder was permitted to enter or pass through. On the whole, documents were not required for travel to sea ports, which were considered open trading points, but documents were required to travel inland from sea ports.
