Burrower → It is formed from "burrow" (from Old English *byrgan*, meaning to hide or shelter) and "-er" (meaning a person who). A burrower is a person or animal that hides or shelters in a burrow.
Think of someone who 'hides' ('burrow') and the '-er' just means a person. A burrower is someone who hides in a burrow.
