Root Explanation

Defoamer → It is formed from "de-" (meaning to remove or reverse) and "foam" (from Old English "fām", meaning a mass of bubbles or froth) and "-er" (meaning a person or thing that performs an action). The word "defoamer" refers to a substance or device that removes or reduces foam.

Memory Tip

Think of 'removing' ('de-') 'foam' — that's what a defoamer does, it helps to eliminate unwanted bubbles.
