The word 书店 (shūdiàn) is formed by directly combining two meaningful characters: 书 (shū), which means "book", and 店 (diàn), which means "shop" or "store". It is a conceptual compound where the first element specifies the type of merchandise and the second element specifies the type of commercial establishment. Together, they create a new, transparent meaning of "bookstore", effectively a "book-shop".
