The Chinese word 下辈子 (xià bèizi), meaning "next lifetime" or "in the next life," is a compound noun formed through semantic combination. It consists of two elements: 下 (xià), which literally means "below" or "next" in a sequence, and 辈子 (bèizi), a noun meaning "lifetime" or "generation." When combined, 下 metaphorically indicates the following or subsequent one in a temporal sequence, thereby modifying 辈子 to specify "the lifetime that comes after the current one." This formation follows a common Chinese structural pattern where a locative or sequential prefix is attached to a core noun to create an abstract, temporal concept.
