Re: Why do Pokorny's roots for water have an "a" in front?

Most scenarios have Armenian going down the west coast of the Black Sea --i.e. that it's a possible descendent of Phrygian and,  before that, some Thraco-Moesian dialect. I don't know whether there is any real evidence to support any of that, though. Besides Iranian adstrate, it also supposedly has a strong Hurrian-Urartaean substrate and some Hattic and Anatolian substrate as well --or so I've read.
