I don't understand any language spoken here. I don’t know at all what they are talking about.
Pamiri Tajik sounds like Persian and therefore more familiar to my ears and I do also understand some words.
Oh wow, not even ossetian?
Either way, its not so weird, since modern persian is a result of middle persian mixed with east iranic languages of Bactria. And kurdish likely has some persian influence, hence why you understand shugnan better(or pamiri tajik just got more persian influence).
Little suprised you dont feel such about balochi language, when balochs descend from same ancestors of kurds, and i been told by a baloch, who said she can understand kurdish spoken in Turkey somewhat
