The term “mestizo” (mestizaje) in Latin America denotes people of mixed European and Indigenous (Indian/Amerindian) ancestry; it is a principal category in the region’s racial taxonomy and Indo‑America classification [2]. Historical colonial casta systems and modern studies both identify mestizo as the label for European–Indian mixture, distinct from “mulatto,” which denotes European–African mixture [3]. Thus, a person of mixed European and Indian blood in Latin America is correctly called a mestizo, while “mulatto” refers to European–African descent; the other options (Meiji, Mau Mau) are unrelated historical terms from other regions.
