it is ok, thanks for acceptance, you are not likely from Slovakia, thus I am aware it is not easy to interpret Slovak rules if Slovak is not your maternity language. Anyway, adjectives derived from gepgraphical names are very rarely used in reality in scrabble games, as they are only few such words composed of smaller number of letters (e.g., tiský,-á, -é, veský, vlcký - derived from river TISA, villges VES, VLKY..). Most of adjective words contain at least 8 and more words.
