The Chinese word **肆意 (sìyì)** is a compound formed by combining two distinct characters: **肆**, which historically means "unrestrained" or "wanton," conveying a sense of reckless abandon, and **意**, meaning "intention," "thought," or "will." Together, they create an adverb describing an action done **wilfully, recklessly, or without any restraint**, where the "intention" (**意**) is characterized by a complete lack of inhibition (**肆**). The term thus semantically fuses the concepts of unchecked desire and deliberate action, typically carrying a negative connotation of acting without regard for rules or consequences.
