The Chinese word **猥亵 (wěixiè)**, meaning "lewd," "obscene," or "to act indecently," is a compound term formed by combining two semantically related characters to intensify the meaning of moral degradation and impurity. The first character, **猥 (wěi)**, carries connotations of being base, vulgar, petty, or despicable, often describing something debased in character. The second character, **亵 (xiè)**, originally referred to improper familiarity, disrespect, or profanation, especially of something that should be sacred or pure. When combined, they create a synergistic term where **猥** emphasizes the crude and vulgar nature, and **亵** stresses the violation of dignity and propriety, together specifically denoting sexually indecent or obscene acts and intentions, thereby forming a strong, formal legal and social term for such misconduct.
