Etymology: Erinaceous, a word for anything hedgehog-like, comes from the Latin "erinaceus", meaning hedgehog. Its ancestry runs back to a Proto-Indo-European root for the animal's spiky, bristling coat, a connection that reveals how ancient the sense of prickliness is. English adopted the word for the scientific and natural-history vocabulary of the 1800s, when naturalists were sorting animals into families and needed adjectives to match. The noun "Erinaceidae" is the family name, formed in Latin from the genus "Erinaceus" and given its taxonomic form by 19th-century zoologists. The adjective and noun share this clean scientific lineage, so the word is a technical coinage rather than an everyday survival from antiquity.
