• noun An Indo-European or Indo-German or Japhetite; a member of that section of the human race which includes the Hindus and Iranians (Persians) as its eastern or Asiatic division, and the Greeks, Italians, Celts, Slavonians, and Germans or Teutons as its western or European division.
• noun Many words still live in India and England that have witnessed the first separation of the northern and southern Aryans, and these are witnesses not to be shaken by any cross-examination. The terms for God, for house, for father, mother, son, daughter, for dog and cow, for heart and tears, for axe and tree, identical in all the Indo-European idioms, are like the watchwords of soldiers. We challenge the seeming stranger; and whether he answer with the lips of a Greek, a German, or an Indian, we recognize him as one of ourselves. There was a time when the ancestors of the Celts, the Germans, the Slavonians, the Greeks and Italians, the Persians and Hindus, were living together beneath the same roof, separate from the ancestors of the Semitic and Turanian races.
