📖 Portuguese Articles & Noun Gender
Definite and indefinite articles, contractions with prepositions, and reliable gender patterns
Two Genders
Like Italian and Spanish, Portuguese nouns are either masculine or feminine — there is no neuter gender. The patterns are very similar to Spanish: • Most nouns ending in -o are masculine: o livro (the book), o menino (the boy). • Most nouns ending in -a are feminine: a casa (the house), a menina (the girl). • Nouns ending in -e or a consonant can be either gender: o nome (the name, masculine), a noite (the night, feminine). Articles, adjectives, and demonstratives all agree in gender and number with the noun they modify.
Definite Articles
Portuguese definite articles are simpler than Italian — there is one form per gender and number, with no special variants for consonant clusters.
| Singular | Plural | |
|---|---|---|
| Masculine | o (o livro) | os (os livros) |
| Feminine | a (a casa) | as (as casas) |
Indefinite Articles
Portuguese is one of the few Romance languages that has plural indefinite articles. While French and Spanish only have singular forms (un/une, un/una), Portuguese has "uns" and "umas" meaning "some" or "a few."
| Singular | Plural | |
|---|---|---|
| Masculine | um (um livro — a book) | uns (uns livros — some books) |
| Feminine | uma (uma casa — a house) | umas (umas casas — some houses) |
Contractions
Portuguese extensively contracts prepositions with articles — these contractions are mandatory, not optional. You will encounter them in nearly every sentence. The four most important prepositions that contract are de (of/from), em (in/on/at), a (to), and por (by/through).
| Preposition | + o | + a | + os | + as |
|---|---|---|---|---|
| de (of, from) | do | da | dos | das |
| em (in, on, at) | no | na | nos | nas |
| a (to) | ao | à | aos | às |
| por (by, through) | pelo | pela | pelos | pelas |
