Borrowed from Portuguese or Spanish casta (“lineage, breed, race”), which the OED derives from Portuguese casto (“chaste”), from Latin castus (“chaste"; "chastity”), Coromines (1987) argues instead for a hypothetical Gothic form *𐌺𐌰𐍃𐍄𐍃 (*kasts, “group, collection of animals”), cognate with English cast, from Proto-Germanic *kastuz, from Proto-Indo-European *h₂ǵ-es-.
