Root Explanation

Fluctuation → It is formed from "fluctuare" (meaning to flow or wave) and the suffix "-tion" (indicating the action or process). The word "fluctuation" refers to the action or process of flowing or wavering, often used to describe changes in levels or amounts.

Memory Tip

Think of something that is 'flowing' or 'wavering' — that's what fluctuation means, as it describes the action of changing levels.
