消息 (xiāo xī) means 'news' or 'information' — any piece of factual, often timely, knowledge shared between people. Literally, 消 (xiāo) suggests 'to disappear' or 'to dissipate', and 息 (xī) means 'breath', 'pulse', or 'sign of life'; together, they evoke the idea of a 'trace' or 'hint' that emerges and spreads — like a breath carrying news across distances. This etymology reflects how information flows: quietly at first, then widely.

The word is neutral in register and used in both spoken and written Chinese. It appears frequently in daily contexts — from checking phone notifications (手机消息) to hearing workplace updates (公司消息) or news headlines (最新消息). Unlike 新闻 (xīn wén), which refers specifically to formal media reports, 消息 is broader and more flexible, covering informal tips, rumors, announcements, or even private messages.
