Dewormer → It is formed from "de-" (meaning removal) and "worm" (from Old English "wyrm", meaning serpent or worm) and the suffix "-er" (meaning a person or thing that performs an action). The word "dewormer" refers to a substance that removes worms from the body.
Think of 'removing' ('de-') 'worms' — that's what a dewormer does, it helps get rid of worms.
