The word **汗水** is formed through a straightforward compound method in Chinese, where two independent characters, each with their own meaning, are combined to create a new, specific term. The first character, **汗** (hàn), means "sweat" or "perspiration," while the second, **水** (shuǐ), means "water." When joined, they create a literal, descriptive compound: **汗**-type **水**, or "sweat-water," which directly and vividly refers to the fluid secreted by sweat glands. This formation follows the common Chinese linguistic pattern of combining a noun with a category word to specify a particular substance or object.
