What does hedgehog mean?
A hedgehog is a small mammal, native mainly to Europe, Asia, and parts of Africa, whose back and sides are covered with sharp spines. When threatened, many hedgehogs curl into a ball so that their spines face outward and provide protection. The word is also used figuratively for someone who is unusually cautious, guarded, or reluctant to commit to an opinion or course of action, comparing that person’s prickly defensiveness to the animal. In ordinary use, “hedgehog” can refer to the animal itself, while “hedgehogs” is the standard plural. The word is useful both as a precise name for a distinctive mammal and as a vivid metaphor for a person who keeps others at a distance.
