From Middle English squirel, squyrelle, from Anglo-Norman esquirel and Old French escurel (whence French écureuil), from Vulgar Latin *scūriolus, diminutive of *scūrius, variant of Latin sciūrus, from Ancient Greek σκίουρος (skíouros, “shadow-tail”, from σκιά (skiá, “shadow”) + οὐρά (ourá, “tail”)). Displaced native Middle English acquerne, aquerne, from Old English ācweorna. See dialectical English con and puristic English oakwern.
