Definition of urchin

The word "urchin" originated in the early 16th century from the Middle English word "yrenshe" or "uroshe," which derived from the Old English term "eornscyeene," meaning "hedgehog." Initially, the term "urchin" was applied to small, spiny, and defensively curled-up creatures, including sea urchins and, to some extent, hedgehogs. During the Middle English period, the term "urchin" transformed in meaning to refer to unruly children, known for their rough and spiky behavior. The connotation of the term "urchin" as a young offender or ruffian dates back to the 16th century's most significant social and economic transitions when children from poor and impoverished backgrounds roamed the streets due to a lack of opportunity and structure. Since then, the use of "urchin" has expanded to apply to young sea urchins as well, reflecting their spherical, defensively spiky bodies reminiscent of the hedgehog spines used metaphorically throughout history. The history of the word "urchin" down the ages carries diverse meanings, from earthbound animals to street-involved youths and marine creatures, with the literal meaning representing innocence while the figurative meaning reviled thuggishness.
