Re: Sanskrit Rta... and related terms

A quick post from the guy wearing the dunce cap:

1) I am truly grateful for all the information being posted.

2) I'm not understanding half of it, but it's all being copied and
saved so that as I progress in my understanding of linguistics I will
be able to return to it again and again.

3A) Going back to the PRE- Indo-Iranian period (aka just prior to the
Proto-Indo-Iranian *rta- attested to by David Watson) ; what would be
the most recent PIE term that also gave rise to European words??

3B) What would those European terms be that developed from that most
recent/latest common PIE ancestor??

Many thanks yet again!
