Korean for Korea is Goryŏ
If the word "Aryan" is of Indo-European origin, the original word root must have been *h₂er-
; /h₂/ is usually reconstructed as [ħ] or [χ]. If it was a Semitic loanword into Indo-Iranian (related to Arabic ħurr
), there is also a /ħ/ there. In any case, Indo-European ablaut means the same root could also have an /o/ there (different prefixes and suffixes can trigger vowel change), while Semitic freely exchanges vowels when declining words.
It is possible that Korean later voiced that sound from [χ] or [ħ] into [ʁ] or [ʕ] word-initially, followed by fortition into [ɢ] (those gutturals are generally hard to pronounce so that's expected), followed by merger into [g] (again because [ɢ] is still a pretty tough sound). Korean would then aspirate voiceless stops and make voiced ones voiceless. Interestingly Korean also has a third, tense series of stops, as do reconstructed Proto-Indo-European (breathy voiced) and Semitic (emphatics).
Original Korean would therefore be: /ħorjə/, which then developed into /korjʌ/ in Korea, and into /a:rya/ in India.
tl;dr: Korean = Aryan.
