行李箱

行李箱 (xínglǐxiāng) is the standard word for a suitcase — the wheeled, hard- or soft-sided travel case you take on a trip. It is a compound of 行李 'luggage, baggage' + 箱 'box, case', so it literally means 'luggage box'. Used in airports, hotels, online shopping, and everyday speech.

Two things often surprise English speakers. First, 行李 alone means 'luggage' as a mass concept ('I have a lot of luggage'), while 行李箱 specifically names the physical suitcase you can count. Second, in mainland China 行李箱 also commonly means the 'trunk' of a car (especially in Taiwan and southern usage); listeners disambiguate by context — at an airport it's a suitcase, at a car it's the trunk.
