歌手 literally means 'song person' — combining 歌 (gē), meaning 'song' or 'singing', and 手 (shǒu), meaning 'person skilled at something' (like in 作家 'writer' or 画家 'painter'). It refers specifically to a professional or performing singer — someone whose main role is singing, often on stage, in recordings, or on television. Unlike the more general term 歌唱者 (gēchàng zhě), 歌手 carries a slightly more formal or career-oriented connotation and is commonly used in media, music awards, and everyday conversation about performers.

This word is neutral in register and appropriate for both spoken and written Chinese. It’s widely used across age groups and contexts — from describing pop idols and opera performers to amateur contestants on talent shows. While it doesn’t specify genre or fame level, adding modifiers like 著名 (famous), 流行 (pop), or 民族 (folk) clarifies the type of singer. It is not used for casual singing (e.g., singing in the shower), which would be described with verbs like 唱歌 instead.
