Re: PIE *a -- a preliminary checklist

The aspiration of stops before H1 and H2 occurs only in Indo-Iranian.

I've been looking into links between PIE and Proto-Uralic and I think
that there was previously just plain voiceless and ejective voiceless.
============
I think it may have been the case in proto-Sapiens
if we accept the numerous cases of roots
where voiced have glottalized variants
as a "proof" that there happened a split.
But that's premature to assert this.

==================

In PPPIE the plain voiceless stops developed aspiration in the
vicinity of back vowels, and these later developed into voiced
aspirates.

==========
Since there was front~back vowel harmony you never see any
PIE roots that mix plain voiceless stops with voiced aspirates (except
in cases with s+voiceless stop and voiced aspirate). I hope to post
something more detailed on the Nostratic group (my recent posts on
Indo-Uralic can be ignored since I've redone the theory in light of
more data).
============
What is the front back vowel harmony ?
The twin sister of the Ablaut joker ?
