The word 闲聊 (xiánliáo), meaning "to chat casually" or "idle talk", is a compound formed through the combination of two meaningful characters: 闲 (xián), which conveys the idea of "leisure", "idleness", or "free time", and 聊 (liáo), which means "to chat" or "to converse". Together, they create a coordinative or complementary compound where the first character modifies the second, specifying the nature of the conversation. Thus, the term literally and conceptually signifies a "leisure chat", a relaxed, informal, and non-purposeful exchange of talk, perfectly encapsulating the act of casual conversation in its formation.
