Have you seen the duckweed covering that pond in the park?

Yeah, it looks like a green carpet floating on the water.

I read that duckweed can actually be used for water purification.

That's interesting! I had no idea it could be so useful.

Root Explanation

Duckweed → The word is formed from "duck" (from Old English *duce*, meaning a waterfowl) and "weed" (from Old English *wēod*, meaning a plant or herb). Duckweed refers to a small aquatic plant often found on the surface of water, commonly associated with ducks that inhabit such environments.

Memory Tip

Think of a 'waterfowl' ('duck') that is often found among 'plants' ('weed') in the water — that's why duckweed is a plant associated with ducks.
