About
The character 檩 is a phono-semantic compound. Its semantic radical 木 (mù) on the left indicates the character relates to wood or timber. The right component 禀 (bǐng) provides its pronunciation. 檩 specifically means a purlin, a horizontal wooden beam running along a roof's length, placed on the main rafters to support the roofing material. This term is used strictly in architecture and carpentry, describing a key structural element in traditional timber-framed buildings. It has no metaphorical or abstract meanings, retaining its precise, utilitarian definition within construction terminology.
