The word 厕所 (cèsuǒ) is formed by combining two characters: 厕 (cè), which originally denoted a side building or, more specifically, a place for waste, and 所 (suǒ), which means a place or location. Together, they literally and logically compose the concept of "the place for waste", evolving in modern usage to mean "toilet" or "restroom". This is a direct semantic compound where the combined meanings of the individual parts create the complete, concrete meaning of the word.
