About
The character "汗", representing sweat, is composed of the water radical (氵) on the left paired with the component "干" on the right, which historically functioned primarily to indicate its pronunciation. Its core meaning has consistently been tied to the physical perspiration produced by the body, a concept directly illustrated by its liquid-related pictographic element. From this concrete foundation, the term naturally expanded to encompass the broader idea of labor or exertion, as seen in words like "流汗" (to sweat, implying hard work). An interesting semantic development occurred through its application as a loan character in the historical title "可汗" (kèhán), used for rulers among certain Central Asian peoples, where it carried no relation to its original meaning but was chosen for its phonetic value.
