Below is a host of questions, implied questions, and questionable statements. I’m trying to get my head around the prehistoric interrelations of pre-Proto-Iranians and pre-Proto-Tocharians based on different “age-levels” of linguistic borrowing and match them with some plausible geographical / archaeological contexts. There are some conundrums here: (1) how did early borrowings from the Bactria–Margiana Archaeological Complex (BMAC) folks get so quickly, by so round about a way, into Tocharian, and (2) why does Tocharian B have an irrigation vocabulary so reminiscent of Central Iranian languages (Sogdian/Avestan; not Saka), borrowed (on phonological grounds) a thousand years (at least) after Tocharians were already knowledgeable about irrigation.
