[Origin: 1490–1500; < F < It razza, of obscure orig.]
—Synonyms 1. tribe, clan, family, stock, line, breed. Race, people, nation are terms for a large body of persons who may be thought of as a unit because of common characteristics. In the traditional biological and anthropological systems of classification race refers to a group of persons who share such genetically transmitted traits as skin color, hair texture, and eye shape or color: the white race; the yellow race. In reference to classifying the human species, race is now under dispute among modern biologists and anthropologists. Some feel that the term has no biological validity; others use it to specify only a partially isolated reproductive population whose members share a considerable degree of genetic similarity. In certain broader or less technical senses race is sometimes used interchangeably with people. People refers to a body of persons united usually by common interests, ideals, or culture but sometimes also by a common history, language, or ethnic character: We are one people; the peoples of the world; the Swedish people. Nation refers to a body of persons living under an organized government or rule, occupying a defined area, and acting as a unit in matters of peace and war: the English nation.
