The Chinese word **清扫 (qīngsǎo)**, meaning "to clean thoroughly" or "to sweep clean," is a compound word formed by combining two characters with related meanings. The first character, **清 (qīng)**, carries the core meaning of "clear," "pure," or "to make clean." The second character, **扫 (sǎo)**, means "to sweep" or "to brush away." When combined in this coordinative structure, where both elements contribute equally to the overall sense, the word gains a more comprehensive and intensive meaning than either character alone—essentially, "to clean by sweeping or clearing away," implying a complete and systematic cleaning action. This method of forming words by pairing synonyms or near-synonyms is very common in Chinese to create precise and vivid terms.
