Mysz is feminine but kapelusz is masculine? Is there a pattern?
I'd say thet the rule is if it ends with sz or ć or ń or anything else "soft" check in dictionary.
with - sz I found only mysz and wesz that are feminine.
Ah thanks for that! Good guideline.
What does wesz mean?
Most of feminine nouns ends with -a, neuter -ie or -o. But it is only in Nominative case.
