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

	Front				Non-Front
	Short	Long	_j	_w	Short	Long	_j	_w
Hi	ɪ	ɪː	ɪj	ɪw	ʊ	ʊː	ʊj
Mid	e	eː	ej	ew	ɐ			ow
Lo	æ	æː	æj	æw		ɒː

/ɐ ɒː/ form similar long-short pair, "/A Aː/" as the other vowels. /ow/ seems in some cases associated with this pair, in others with /ʊ ʊː ʊj/ (and in most, there's just no telling). There is no **/Aj/ of any sort; if there ever was, it might have previously merged into /æj/.

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