The Chinese word 止血 (zhǐ xuè) is formed through the combination of two characters: 止 (zhǐ), meaning "to stop" or "to halt", and 血 (xuè), meaning "blood". Together, they create a verb-object compound where the first character acts upon the second, literally meaning "to stop the blood". This logical and semantic construction directly describes the action of stanching bleeding, making it a transparent and efficient compound word commonly used in both medical contexts (e.g.,止血贴, band-aid) and everyday language.
