aryan
adj.adj. relating to a group of people who spoke an ancient language in India and Europe. In history, this word was also used by some groups to describe a supposed 'master race', which makes it very sensitive and often offensive today.
adj. relating to the Indo-Iranian languages or the people who spoke them; in a historical and political context, associated with 19th-century racial theories and Nazi ideology. Often capitalised; usage in a racial sense is highly controversial and generally considered offensive.
Historians study the migration of ancient Aryan tribes.
Scholars must distinguish between the legitimate linguistic study of Indo-Aryan languages and the pseudoscientific racial myths that emerged in the nineteenth century.
Apparently originally from Classical Latin Ariānus, from Ariāna, probably after German Arier, arisch and subsequently reinforced by related Sanskrit आर्य (ā́rya, “noble; noble one”) and + -n. The Sanskrit word is from Proto-Indo-Iranian *áryas (the original Indo-Iranian autonym). Borrowed into English in the 19th century, at first as a term for the Indo-Iranian languages, and later partly extended to the Indo-European languages and peoples following a theory by Friedrich Schlegel that connected the Indo-Iranian words arya/ā́rya with German Ehre (“honor”) and some older Germanic names, thus assuming that it was the original Indo-European autonym meaning "the honorable people". The original meaning of the Indo-Iranian autonym and its possible Indo-European origin/cognates are disputed (see the Wikipedia article for further details). The same Proto-Indo-Iranian root is the ultimate source of the country name Iran.
Typically used as an adjective to modify nouns like 'tribes', 'languages', or 'ideology'.
