Root Explanation

Wormer → The word 'wormer' is formed from 'worm' (from Old English 'wyrm', meaning serpent or snake) and '-er' (meaning a person who). A wormer is a person or agent that deals with worms, typically in the context of treating or removing them from animals or humans.

Memory Tip

Think of someone who deals with 'worms' ('worm') — the '-er' just means a person. A wormer is someone who treats or removes worms.
