Half-caste is a term used for individuals of multiracial descent. It is derived from the term caste, which comes from the Latin castus, meaning pure, and the derivative Portuguese and Spanish word casta, meaning race. Terms such as half-caste, caste, quarter-caste and mix-breed were used by colonial officials in the British Empire during their classification of indigenous populations, and in Australia used during the Australian government's pursuit of a policy of assimilation. In Latin America, the equivalent term for half-castes was Cholo and Zambo. Some people now consider the term offensive.
