The word Aryan actually refers to what?

The term "Aryan" originally refers to the group of ancient peoples who spoke Indo-Iranian languages and is associated with the early Indo-European migrations into the Indian subcontinent and parts of Iran. In a linguistic context, it denotes the cultural and ethnic identity of these groups. However, the term has been misappropriated in modern history, particularly by Nazi ideology, to promote a false notion of racial superiority. Today, it is important to understand its historical and linguistic roots rather than its politically charged interpretations.
