The word **行李箱** (xínglǐxiāng) is a logical, descriptive compound noun formed by combining three characters: **行** (xíng) meaning "to travel," **李** (lǐ) which is an archaic term for "luggage" or "baggage" (originating from the phrase "行李" for a traveler's belongings), and **箱** (xiāng) meaning "box" or "trunk." Thus, the term constructs the meaning sequentially as a "travel-luggage-box," effectively and intuitively creating the modern word for "suitcase" or "travel trunk."
