And what is the semantical difference with oči Kateřiny se mi líbí?
No semantical difference. It just sounds better but both are grammatical.
It is like asking for the difference between Kateřina's eyes and eyes of Kateřina.
Hello! Katerininy oči se mi líbí. May I ask why it is not "Katerinina"? I thought "oči" is nominative, neutral and plural. Thank you for your help.
oči and uši are like děti
The plural is feminine even though the singular is neuter.
Thank you very much for your nice advice always!
(I should have remembered them in the previous lessons...)
