"My hat"

Translation: Mój kapelusz

[edbecker52]

Mysz is feminine but kapelusz is masculine? Is there a pattern?

[immery]

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.

[edbecker52]

Ah thanks for that! Good guideline.

[jabramsohn]

What does wesz mean?

Most of feminine nouns ends with -a, neuter -ie or -o. But it is only in Nominative case.
