Language /
Polish was chosen the HARDEST LANGUAGE in the world to learn... :D [1558]
Simplified basic rules on Polish vocative (there may be an exception here or there):
Male names the vocative = the locative, if you can say "about ...." thats also the vocative
If you don't know the locative the ending is
if the final consonant is hard, then the ending is -(J)e (that is e preceded by softening the consonant before it)
Robert = Robercie!
Ryszard = Ryszardzie!
Paweł = Pawle!
Wiesław = Wiesławie!
if the last consonant is already soft or -sz, -rz, -l, -ch or -k then the vocative is -u
Januszu!
Lechu!
Karolu!
Jacku!
Jasiu! (from jaś
Kazimierzu!
For women if the final consonant is hard then -a becomes -o
Anna = Anno!
Agnieszka = Agnieszko!
Barbara = Barbaro!
If the final consonant is soft, then -ia becomes -iu
Ania = Aniu
Asia = Asiu
Zosia = Zosiu
but if the final is -ja or -ia (where -i- is pronounced as -j-, almost like a separate vowel) then they act like hard stems
Natalia = Natalio
Patrycja = Patrycjo
If the final consonant is -l- or -sz- I'm not so sure, I'm pretty sure I've heard both Elo and Elu and Olu and Olo (I think the forms in -u are more common but I'll leave that for Poles to debate).
The vocative of Pan is Panie and the vocative of Pani is .... Pani. These aren't used on their own though, they're followed by a name or title.
Panie Norbercie! Pani Krystyno! Panie kolego! (Mr Colleague!)
