‘套话’ literally combines 套 (tào), meaning 'set,' 'template,' or 'formula,' and 话 (huà), meaning 'speech' or 'words.' Together, it refers to overused, stereotyped expressions lacking sincerity or original thought—often heard in official speeches, bureaucratic documents, or polite but empty social exchanges. These phrases follow predictable patterns and convey little real meaning or personal engagement.

Common contexts include political announcements, corporate meetings, graduation speeches, or formal letters where speakers rely on safe, rehearsed language instead of authentic expression. While not inherently negative, 套话 carries a mildly critical or weary connotation—implying insincerity, laziness, or avoidance of genuine communication. Native speakers often roll their eyes or joke about ‘hearing another round of 套话’ when encountering predictable, hollow rhetoric.
