did the slavic methathesis indeed appeared just in the 8-th
century or was this a phenomenom which appeared already in
common slavic, until the slavic languages separated
themself?Piotr mentionated "the first " emthathesis in slavic
should be known from the 8-th century first.
but in which slavic then? just south slavic or how is this
phenomenom in the other slavic languages to documentate?
