The Chinese word 私生活 (sīshēnghuó, meaning "private life") is a compound noun formed through semantic combination. It consists of the morpheme 私 (sī), which means "private" or "personal", directly modifying the morpheme 生活 (shēnghuó), which means "life" or "livelihood". The structure follows a common modifier-head pattern in Chinese, where the first element (私) specifies the type or domain of the second element (生活), thus creating the specific meaning of "the sphere of life that is personal and not public", akin to the English phrase from which it may be a calque. This formation is both logical and transparent, clearly conveying its meaning through the sum of its parts.
