The Chinese word "优惠券" (yōuhuìquàn) is a compound noun formed by combining two distinct morphemes: "优惠" (yōuhuì), which means "discount," "preferential," or "a favorable offer," and "券" (quàn), which means "coupon," "ticket," or "voucher." The first part, "优惠," describes the quality or type of benefit, while the second part, "券," specifies the physical or digital form of the instrument. Together, they create a precise and commonly used term that literally translates to "preferential coupon" or "discount coupon," efficiently conveying the concept of a ticket or certificate that entitles the holder to a reduced price or special offer.
