Original sentence: Half caste - along with terms such as caste, quarter caste and others -  were widely used by ethnographers in British colonies in attempts to classify natives.In Latin America, the equivalent term for half castes was Cholo.It is derived from the term Caste, which comes from the Latin castus, meaning pure, and the derivative Portuguese and Spanish casta, meaning race.The term was immortalized in the Half-Caste Act, whereby the Australian government could seize such children in order to, in theory, provide them with better homes than those afforded typical Aborigines.While the term half caste tends to evoke the understanding of it referring to the offspring of two persons of two different pure bloods or near pure bloods, in other languages, such as Mandarin Chinese, the words half caste and mixed ethnicity or multi ethnic; are the same word hun-xue (混血)
Edited sentence: Caste comes from the Latin castus, meaning pure, and the derivative Portuguese and Spanish casta, meaning race.For example: hun-xue 混血 means both half caste and multi ethnic.It is immortalized in the Half-Caste Act, whereby the Australian government could seize such children in order to, in theory, provide them with better homes than those afforded typical Aborigines.It was in common usage, and considered an entirely acceptable adjective for people, from at least between the mid-19th century and mid-20th century.The term is often incorrectly believed to have some sort of relationship with the Indian caste system, but the fact that children born to mixed Indian and British parentage were termed either Eurasian or Anglo-Indian rather disproves this theory.Today, the term is much more prominent in commonwealth countries than in the United States, possibly indicating that its usage came about after America's independence.Whether or not the term is offensive is a matter of considerable debate, and opinions vary throughout the Anglophone world.While the term half caste tends to evoke the understanding of it referring to the offspring of two persons of two different pure bloods or near pure bloods, in other languages, such as Mandarin Chinese, the words half caste and mixed ethnicity or multi ethnic; are the same word and are not recognized as separate words with different meanings
