:The best solution to this and other problems already discussed in this talk page is in my opinion: make a Disambiguation and write something like 
 :::Arya, thus adjective and noun aryan, may refer to 
 :::*Arya in Indian linguistic and other contexts (cf. Arya (Indian context)) 
 :::*Arya in Iranian linguistic context (cf. Arya (Iranian context)) 
 :::*Arya in European racial context (cf. Aryan (Nazi racial context)) 
 :The article has already all of these but one good editor should make the split.
