Word OriginOld English impa, impe ‘young shoot, scion’, impian ‘to graft’, based on Greek emphuein ‘to implant’. In late Middle English, the noun denoted a descendant, especially of a noble family, and later a child of the devil or a person regarded as such; hence a “little devil” or mischievous child (early 17th cent.).
