Definicja radical

Group of strokes in a Chinese character that is treated as a unit for the purposes of sorting, indexing, and classification. A character can contain more than one element that is recognized as a radical, but each character contains only one element, called the "main radical," that is used as the indexing radical. The main radical often gives a hint as to the general meaning of the character, and other radicals in the character might indicate how the character is pronounced.
