Word Origin & Etymology

Borrowed from Old French irechon ('hedgehog'), ultimately from Latin ericius, derived from er ('hedgehog'). The marine echinoderm was named 'sea urchin' after its spiky resemblance to the land mammal, and the word's application to mischievous or ragged children arose from old folkloric associations of hedgehogs with goblins and elves.
