A burrow is a hole or tunnel in the ground made by an animal for shelter or storage. As a verb, it means to dig or move through something by making tunnels.
From Middle English “burwe,” meaning “hole or lair,” related to Old English “burh,” meaning “fortified place” or “town.” The sense shifted from human shelters to animal tunnels.
A burrow is like a tiny underground fortress, and it’s a cousin of the word “borough” in town names. Animals and humans both carve out protected spaces; we just do it with bricks and theirs with claws.
