The word "阉割" is formed by combining two characters: "阉", which signifies castration or eunuch, structured with the radical "门" implying enclosure and the phonetic element "奄" indicating pronunciation, and "割", meaning to cut, structured with the radical "刂" representing a knife and the component "害" contributing to sound and meaning. Together, "阉" defines the purpose related to castration, while "割" specifies the action of cutting, resulting in a compound meaning "to castrate" through surgical removal.
