Etymology

Origin of porcupine

1375–1425; late Middle English porcupyne, variant of porcapyne; replacing porke despyne < Middle French porc d'espine thorny pig. See pork, spine

Explanation

A porcupine is a prickly rodent, a round forest animal that's covered in sharp, protective quills. How do you pet a porcupine? Very, very carefully. Porcupine comes from Latin roots, porcus, "pig," and spina, "spine or quill." Fittingly, a regional name for the porcupine is "quill pig." The porcupine is famous for its spines, which become spikier when it's afraid or angry. Less well known is the fact that porcupines also clatter their teeth loudly as a warning — all the more reason for your dog to feel embarrassed after she ends up with a nose full of porcupine quills.
