About

枢 (shū) is the simplified form of 樞, a phono-semantic compound. The wood radical 木 (mù) on the left points to wooden construction, while 区 (qū) on the right provides the sound; the traditional character uses the phonetic 區. Originally, it referred to the central wooden pivot or hinge of a door, enabling it to swing open and closed. Because this pivot is essential to the door's function, the meaning expanded to any vital hub or axis in a system, such as a transportation hub or communication node.
