urchin

Picture a hedgehog: tiny, dark-eyed, and bristling with defensive spikes. That prickly creature supplied Latin ērīcius, which passed through Vulgar Latin and Old Northern French before appearing in Middle English as yrchoun around the medieval period. English then used the same word for the sea urchin, whose shell looks like a miniature armored hedgehog stranded on the seafloor. By the late sixteenth century, “urchin” had also become a nickname for a small, ragged, or mischievous child—apparently because children could be just as troublesome and spiky in temperament. French hérisson and Italian riccio are linguistic cousins, so the word’s family portrait contains both street children and sea-floor pincushions: different creatures, same defensive silhouette.
