Root Explanation

Topminnow → The word is formed from "top" (meaning the highest point) and "minnow" (from Middle English *minowe*, meaning a small fish). The term "topminnow" refers to a small fish that is often found near the surface of the water, hence its name indicating its position at the top.

Memory Tip

Think of a small fish that swims at the 'top' of the water — that's why it's called a topminnow.
