Difference between passport and transport in Korean
여권·교통

여권passport
A passport (여권) is an official book or card you use to travel to other countries. It shows who you are and what country you are from. People usually carry it at the airport or when crossing a border.

교통transport
Transport means the system or way people move from one place to another, like buses, trains, cars, and subways. In Korean, 교통 is often used when talking about how easy, busy, or inconvenient transportation is in an area. You can use it for public transportation, traffic, and getting around a city.
The difference
This means buses, trains, cars, and the system of moving people. It is about travel methods, not a personal travel document.
