Proto-Persian'

Thanks to some of the oldest languages attested in writing (Tsonboran especially) belonging in the Persian' family, this protolang can reliably be traced all the way back to about -8ka, despite the family being relativly small. (Out of real language families, the "analog" of this might be Dravidian.)

Vowels

Apparently former */ɑ ɑːɑj ɑw/ → /ɐ ɒː æj ow/ and */ʊw/ → /ow/.

A medial glide forms a difthong with a preceding short vowel, but not a preceding long one.
