Root Explanation

Sapwood is formed from "sap" (from Old English *sæp*, meaning fluid or juice) and "wood" (from Old English *wudu*, meaning tree or timber). The term refers to the living outer layer of a tree that transports nutrients and water, which is the fluid part of the wood.

Memory Tip

Think of 'sap' as the fluid that nourishes the tree, and 'wood' as the structure of the tree. Sapwood is the part of the tree that carries this nourishing fluid.
