Billpawl, thou hast raised a very worthwhile point. But to whom? Michal himself?
Who on earth uses the ancient word "Ku" in Poland?
I don't know, but I hear a Slovakian ku quite a lot. But I am learning neither Russian nor Slovakian.
-u
-owi
When it is applied to a man's name, which is used? I have a book that states that the dative is more often used with people's names than with other nouns, but then it doesn't actually give any examples of how to use the dative with names.
Crude tool that is google, I tried it anyway.
Jurku - a small number of random results
Jurkowi - a much larger number of results, some of which looked like they were definitely in a dative context.
-owi it is then, unless anyone can give me any exceptions or corrections.
