Catalan nouns

Every noun has a gender in Catalan (masculine/femininine).

Plurals are usually formed by adding s at the end, but there are more complicated cases:

-ca becomes -ques
-ga becomes -gues
-gua becomes -gües
-ix becomes -ixos
-qua becomes -qües
-s becomes -sos
-tg becomes -tjos
-tja becomes -tges
-a becomes -es in other cases
If a noun ends in a stressed vowel, the plural is formed by removing the accent and adding -ns.
