The word 博物馆 is formed by combining three meaningful characters, each contributing a layer of concept to create the final term. It begins with 博 (bó), meaning "broad" or "extensive", which modifies the next character, 物 (wù), meaning "object" or "thing", together suggesting "a broad collection of objects". This compound is then housed by the final character 馆 (guǎn), meaning "building" or "hall". Thus, the formation progresses logically from the abstract idea of extensive collection, to the physical objects themselves, and finally to the institutional structure that contains them, building the complete concept of "museum" step-by-step from its constituent ideas.
