'Bad news' literally combines three characters: 坏 (huài) meaning 'bad' or 'unfavorable', 消 (xiāo) meaning 'to disappear' or used here as part of the compound for 'information', and 息 (xī) meaning 'breath' or 'news'. Together, 消息 (xiāo xī) means 'news' or 'information', and adding 坏 makes it specifically 'unfavorable' or 'distressing' news. It’s a neutral-to-formal noun commonly used in spoken and written Chinese to report unwelcome developments—like health setbacks, work problems, or personal disappointments.

The phrase carries emotional weight but isn’t inherently dramatic; tone and context determine how serious it sounds. Unlike more literary or formal alternatives (e.g., 噩耗), 坏消息 is everyday and widely appropriate—from telling a friend about a canceled plan to reporting a minor accident. It’s often introduced with phrases like '我有个坏消息...' ('I have some bad news...') or softened with hedges like '可能是个坏消息' ('This might be bad news').
