[tied] Re: Accepted cognates of Arya?

--- In cybalist@..., "Piotr Gasiorowski" <gpiotr@...> wrote:.> PIE
*k^ developed into a palatal affricate (like English "ch") in Indo-
Iranian. This sound, preserved as an affricate in Nuristani,
developed into Indo-Aryan fricative /s'/. The Iranian languages
show /s/ for the most part, but Old Persian had a distinct reflex
(/þ/ = "th"). Old Persian also has /s/ for old *k^w (Skt. s'v), while
the rest of Iranian has /sp/. These developments were much later than
the common Iranian weakening of *s, so that any *s derived from *k^
is preserved in Iranian (being too late to become *h).

In the following examples, what would be the PIE consonants cognate
with Vedic 's.t.'

is.t.i, is.t.aka, is.t.ika 'brick' (Vedic)
is'tiia (Avestan)
zCmo-is'tuua 'clay brick' (Avestan).
