The term 淫荡 is a compound word formed through the combination of two distinct Chinese characters, each contributing to the overall pejorative meaning. The first character, 淫 (yín), carries the core connotations of "excessive", "licentious", or "obscene". The second character, 荡 (dàng), means "to sway", "unrestrained", or "dissolute", evoking a sense of wild, improper behavior. When paired, 淫 provides the thematic focus on lewdness and sexual immorality, while 荡 intensifies this by emphasizing a lack of restraint and decency. Thus, the compound semantically merges to form a single, strong adjective meaning "lewd", "lascivious", or "wanton", describing someone or behavior perceived as morally debauched and sexually promiscuous beyond accepted social norms.
