How is rotted wood described when compared to sound wood?

Rotted wood is described as brash when compared to sound wood because it loses its structural integrity and becomes less capable of withstanding stress and pressure. This term indicates that the wood easily breaks apart or crumbles when subjected to force, reflecting its deteriorated state. Brash wood is often dry and brittle, making it significantly weaker than sound wood, which maintains its strength and flexibility. In contrast, sound wood possesses properties like resilience and density, making it robust and able to absorb shock without failing. The characterization of rotted wood as brash highlights the contrast in durability and functionality between deteriorated and healthy wood.
