The word "路由器" is formed by combining three characters: 路 (lù), meaning "road" or "path"; 由 (yóu), meaning "through" or "from"; and 器 (qì), meaning "device" or "instrument". The segment 路由 together conveys the concept of "routing", as in directing data along network paths, while 器 specifies it as a physical apparatus. Thus, the term literally translates to "routing device", directly indicating its function as a network router.
