媒体 (méi tǐ) is a compound noun meaning 'media'—specifically mass media such as newspapers, television, radio, websites, and social platforms. The first character 媒 (méi) means 'intermediary' or 'go-between', historically referring to matchmakers but extended to denote channels that connect information with audiences. The second character 体 (tǐ) means 'body' or 'system', suggesting an organized institutional framework. Together, 媒体 conveys the idea of formalized systems for disseminating news, entertainment, and public discourse.

This word is widely used in both formal and informal contexts—e.g., in discussions about journalism, digital communication, or societal influence. It’s typically uncountable in Chinese (no plural marker needed), and often appears with modifiers like 大众 (dàzhòng, 'mass'), 新 (xīn, 'new'), or 传统 (chuántǒng, 'traditional') to specify types. Unlike English 'media', which can be singular or plural, 媒体 is always treated as singular in grammar.
