Conversation

Did you know that the dark part of the tree is called heartwood?

Really? I always thought it was just regular wood.

Yeah, it's actually denser and more durable than the sapwood.

That makes sense! I guess that's why it's used for furniture.

Root Explanation

Heartwood is formed from "heart" (from Old English "heorte", meaning the central or most important part) and "wood" (from Old English "wudu", meaning the material that comes from trees). The term "heartwood" refers to the dense, inner part of a tree trunk that provides strength and support, symbolizing its core or essential structure.

Memory Tip

Think of the 'central part' ('heart') of a tree being its 'wood' — that's why heartwood is the essential, strong part of the tree.
