Groundhog → The word is formed from "ground" (from Old English *grund*, meaning the surface of the earth) and "hog" (from Old English *hogg*, meaning a young pig or a term for a male animal). The term "groundhog" refers to a burrowing animal that lives in the ground, resembling a pig in size and shape.
Think of the 'ground' where this animal lives and 'hog' which relates to its size and shape — a groundhog is an animal that lives in the ground and resembles a hog.
