About
The word "棺材板" is formed by sequentially combining three characters: 棺, meaning "coffin"; 材, meaning "material" or "wood"; and 板, meaning "board" or "plank". The compound 棺材 directly denotes a coffin, and the addition of 板 specifies the wooden boards used in its construction, resulting in a term that literally refers to coffin planks.
