Conversation

Have you ever seen how a tailrace works at the old mill?

No, I haven't! What's so interesting about it?

It's fascinating to watch the water flow through the tailrace after it powers the wheel.

That sounds cool! I'd love to check it out sometime.

Root Explanation

Tailrace → The word is formed from "tail" (from Old English *tægel*, meaning the rear or end part) and "race" (from Old English *ræce*, meaning a channel or course). A tailrace refers to the channel that carries water away from a water wheel or turbine, essentially the path at the rear of the wheel.

Memory Tip

Think of the 'rear part' ('tail') and the 'channel' ('race') that carries water away — that's what a tailrace does.
