Mischling ("crossbreed" in German, plural: Mischlinge) was the German term used during the Third Reich to denote persons deemed to have only partial Aryan ancestry. The word has essentially the same origin as mestee in English, mestizo in Spanish and métis in French. In German, the word has the general meaning of hybrid, mongrel, or half-breed.
