The Chinese word "后期" is a compound noun formed by combining two meaningful characters: "后" (hòu), which means "later," "after," or "behind," and "期" (qī), which means "period," "phase," or "scheduled time." When combined, they create a new semantic unit that literally means "the later period" or "the later phase," and it is used to refer to the final stages of a process, such as post-production in filmmaking, the latter part of a historical era, or the concluding phase of a project. This formation follows the common Chinese syntactic pattern where two independent, related morphemes are joined to express a more specific, compound concept.
