The Chinese word 到期 (dàoqī) is a compound word formed through a logical verb-object grammatical relationship between its two constituent characters: the verb 到 (dào), meaning "to arrive" or "to reach", and the noun 期 (qī), meaning "a set period", "term", or "deadline". Combined, they create a verb meaning "to arrive at the appointed period" or "to fall due", directly and transparently describing the point in time when a predefined term or contract concludes, such as a maturity date for a financial instrument or the expiration of an agreement.
