📖 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.

Tip: If you already know Spanish, you know about 95% of Portuguese genders — they are nearly identical. The main exceptions are a handful of words: "o leite" (milk, masculine in Portuguese but "la leche" is feminine in Spanish).

Definite Articles

Portuguese definite articles are simpler than Italian — there is one form per gender and number, with no special variants for consonant clusters.

SingularPlural
Masculineo (o livro)os (os livros)
Femininea (a casa)as (as casas)
O João e a Maria são amigos. Os livros estão na mesa.João and Maria are friends. The books are on the table.
Tip: Portuguese uses definite articles before people's names — "o João," "a Maria" — which Spanish does not. This sounds strange at first but is completely standard in Portuguese.

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."

SingularPlural
Masculineum (um livro — a book)uns (uns livros — some books)
Feminineuma (uma casa — a house)umas (umas casas — some houses)
Comprei uns livros e umas revistas.I bought some books and some magazines.
Tip: The plural indefinite articles "uns/umas" are genuinely useful — they fill a gap that other Romance languages work around. "Uns amigos" = "some friends" / "a few friends."

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)dodadosdas
em (in, on, at)nonanosnas
a (to)aoàaosàs
por (by, through)pelopelapelospelas
Eu venho do Brasil. O livro está na mesa. Vamos ao cinema. Passei pela praia.I come from (de + o =) Brazil. The book is on (em + a =) the table. Let's go to (a + o =) the cinema. I passed by (por + a =) the beach.
Tip: These contractions are not optional — you must always use "do" instead of "de o," "na" instead of "em a," etc. They become automatic with practice, but pay close attention when reading to recognize the preposition + article combination.

Gender Patterns

These suffix-based patterns will help you predict the gender of unfamiliar nouns with high accuracy.

Ending / PatternGenderExamples
-çãoAlways femininea nação, a estação, a ação
-dadeAlways femininea cidade, a universidade, a felicidade
-agemAlways femininea viagem, a imagem, a linguagem
-adeAlways femininea saudade, a liberdade
-orUsually masculineo amor, o calor, o professor
-ema (Greek origin)Masculineo problema, o sistema, o tema
-menteNot a noun — adverbfelizmente, rapidamente
Tip: Very similar to Spanish gender patterns — -ción/-ção, -dad/-dade, -or/-or are all feminine/masculine in both languages. If you know Spanish, trust your instincts for Portuguese gender.
