Dear Seelanzhane,
Having passed the big 4-0, one realsies that memory ain't
what it used to be.
I seem to rememebr that soemwhere Alfred Senn put forward
a theory that a sort of Balto-Slavic dialect continuum was "disrupted
by a Persian invasion around 500 BC".
Has anyone got a more exact reference?
Thanks in advance,
Robert Orr
