The Chinese word "车窗" (chē chuāng) is formed through the standard morphological process of compounding, where two independent and meaningful characters are combined to create a new, specific term. The first character, "车" (chē), means "vehicle" or "car", and the second character, "窗" (chuāng), means "window". When joined, they create a nominal compound where the first element modifies the second, resulting in the precise meaning of "car window", a window that is specifically part of a vehicle, distinct from other types of windows like a house window ("窗户"). This structure follows the common Chinese word-formation pattern of a modifier (what kind?) followed by a head noun (what thing?).
