Noun is a word that names beings, things, places, qualities, actions or states. Portuguese noun inflect for gender and number.


Portuguese has two genders: masculine and feminine. Gender classification is purely grammatical and it only matters when adding articles or Adjectives.

Besides the animate nouns, there is no strict rule for the gender. It is meaningless to say that, in Portuguese, a chair (cadeira) is feminine or a book (livro) is masculine. Compared to English, however, is a good feature of languages like Portuguse the more specific difference between a male friend (amigo) or a female friend (amiga).

The normal ending are -o for masculine and -a for feminine. This is not a general rule, however; actually, few nouns follow it.
