Wikipedia definition
2. Radical (Chinese character)A Chinese radical is a component of a Chinese character. The term may variously refer to the original semantic (meaning-bearing) element of a character, or to any semantic element, or, loosely, to any element whatever its origin or purpose. The term is commonly used to describe the element under which a character is traditionally listed in a Chinese dictionary, which is often semantic but may sometimes be a phonetic or merely artificially extracted portion of the character.
