vermin: [13] Vermin comes via Old French vermin from Vulgar Latin *vermīnum ‘noxious animals’, a derivative of Latin vermis ‘worm’. This came ultimately from Indo-European *wrmi-, which also produced English worm, and among the other contributions it has made to English are vermicelli [17] (from an Italian diminutive meaning ‘little worms’), vermicular [17], vermiculite [19] (so called because when heated it produces wormlike projections), vermifuge [17], and vermilion.
