The word 大奖 (dàjiǎng) is a standard Chinese compound noun formed through a straightforward modifier-head structure. It consists of the modifier 大 (dà), meaning "big" or "major", which descriptively qualifies the core head noun 奖 (jiǎng), meaning "prize" or "award". Therefore, the two characters combine logically to mean "big prize" or "major award", where the first element specifies the scale or importance of the second. This pattern is highly productive in Chinese, analogous to English compounds like "grand prize".
