About
The character 椽 (chuán) is a phono-semantic compound denoting the rafters in traditional architecture. Its semantic radical 木 (mù) on the left indicates the object is made of wood. The right component 彖 (tuàn) functions as the phonetic element, guiding the pronunciation. Historically, it specifically referred to the sloping wooden beams that extend from the ridge pole to the eaves, bearing the weight of the roof covering. The character has maintained this precise technical meaning, though it occasionally appears in literary metaphors for a foundational support within an organization or state.
