The word 销量 (xiāoliàng), meaning "sales volume", is a standard compound noun formed by combining two meaningful characters: 销 (xiāo), which means "to sell" or "to market", and 量 (liàng), which means "quantity" or "amount". It follows a common grammatical structure in Chinese known as a modifier-head or verb-object construction, where the first character (销) acts as the modifier describing the type or domain of the second character (量), which is the core head noun. Thus, the compound literally and logically translates to "the quantity (resulting from) selling", efficiently conveying the concept of the amount of goods sold.
