Some time ago I started doing some research on the word 'Aryan'. The initial research had some unexpected results. I learned a number of things I had never seen anywhere else. Much of this is information which can be found in standard, mainstream sources used for Indo-European historical linguistics, but I noticed there wasn't a lot of interest in compiling the various cognates in one place and giving them a thorough analysis.
There's a certain stigma of 'Nazism' associated with the word which probably explains the academic neglect. Some people actually have the mistaken idea now that cognates of Sanskrit आर्य (ā́rya-) are limited to Indo-Iranian languages. This belief could not be further from the truth.
First I'll post something old I made a while back. Then I'll post a rough draft I'm working on. If anyone has ideas regarding the best way to format this so it looks good, let me know. I just wanted to post this some place quiet where the thread won't disappear too quickly.
