I want to know the answer to the following question:
What Proto-Indo-European term means "skillful assembler?"
All the background I'm provided with is that "The Middle Iranian ērān and aryān are oblique plural forms of gentilic ēr- (Middle Persian) and ary- (Parthian), both deriving from Proto-Iranian *arya- (meaning "Aryan," i.e., "of the Iranians"), argued to descend from Proto-Indo-European *ar-yo-, meaning "skillful assembler."". Is that enough to answer the question?
Answer: yes
