Re: [tied] PIE Stop System

I have been doing a little more hunting on voiceless aspirates.
There are only 4 that are supported by both Greek and Skt, one of those a
Lall-word.
There are a couple supported by Armenian and one other language, but I do
not think we can say an Armenian aspirate (or initial #sx-) "proves" the
original PIE was an aspirate.
There are some other suggested roots with voiceless aspirates, for which the
aspiration is supported only by one language.

Is this really "ample" evidence, which "demands" the reconstruction of
voiceless aspirates?

Aspirate suggested by Armenian only:
*phol, *math
Aspirate suggested by Greek only:
*deph, *kantho, *kwenth, ske:th
Aspirate suggested by I-I only:
*kapho, * menth, *wyeth (set), *wreth (even P is doubtful)
(Of these 4, the 2nd and 3rd show a laryngeal (so printed in Rix, both
with -th2), and the fourth is highly unlikely)

Aspirate suggested by Armenian and Greek:
*perth,
also *(s)meukh but both languages have -g- forms as well.
Aspirate suggested by Greek and I-I:
*k^iph, *k^onkho, *khakha, *makhos
Aspirate suggested by Skt and Armenian (but where does Armenian #sx- come
from?):
*skhel

Aspirate required by no language:
*eph, *rek^Th (the "aspirate" here is thorn!)
Aspirate suggested by Skt, but denied by Greek:
*kenth

A full list with Pokorny references follows if anyone is still interested.
