How to use adjectives in Brazilian Portuguese?

By: Fabiana Dametto Oliveira

Adjectives are words used to describe a noun. In Brazilian Portuguese, they are usually placed after the noun they describe, and they must agree in gender (masculine or feminine) and number (singular or plural) with the noun they describe:

edifício alto
Translation: tall building
masculine singular
montanhas altas
Translation: tall mountains
feminine plural

As you can see, the ending of an adjective changes depending on the gender and number of the noun it describes. Most of the time, feminine adjectives will end in -a and you can add an -s to an adjective to make it plural, though there are some exceptions to both of these rules.

Are you curious to know more about the rules of using adjectives in Brazilian Portuguese? Let me explain!

How does adjective agreement work in Brazilian Portuguese?

In Brazilian Portuguese, adjectives agree with the gender and number of the noun they describe. This means that they take on a form that reflects whether the noun is masculine or feminine, singular or plural. For example:

MasculineFeminine
Singular
o carro barato
Translation: the cheap car
a casa barata
Translation: the cheap house
Plural
os carros baratos
Translation: the cheap cars
as casas baratas
Translation: the cheap houses

In the next sections, we’ll review how to modify the gender and number of adjectives to agree with the nouns they describe, starting with gender agreement!

Gender of adjectives: masculine vs. feminine

Gender in Brazilian Portuguese is marked on the adjective according to three main patterns. You can usually tell which pattern an adjective follows by looking at the ending of the masculine singular form (which is the form you will find in the dictionary). Let’s have a look at each pattern!

Adjectives ending in ‘-o’

If a masculine singular adjective ends in -o, then you’ll replace that -o with an -a to make it feminine.

MasculineFeminine
o menino educado
Translation: the polite boy
a menina educada
Translation: the polite girl
o céu bonito
Translation: the beautiful sky
a praia bonita
Translation: the beautiful beach

An exception: Adjectives ending in ‘-ão’

There are a few adjectives that end in -ão in Brazilian Portuguese. For these nouns, you will usually create the feminine form just reducing the ending to , but with adjectives that function as intensifiers, you’ll replace -ão with -ona.

MasculineFeminineEnglish
são
sã

sane

cristão
cristã

Christian

chorão
chorona

whiny

Adjectives ending in ‘-u,’ ‘-ês,’ and ‘-or’

When a masculine singular adjective ends in -u, -ês, and -or in Brazilian Portuguese, we usually form the feminine by adding an -a to the masculine form.

EndingMasculineFeminineEnglish
-u
cru
crua

raw

-ês
português
portuguesa

Portuguese

-or
(see Exception! below)
encantador
encantadora

enchanting

Adjectives with no variation in gender

Some adjectives, especially those ending in -a, -e, -l, -ar, -s, -z and -m, as well as adjectives ending in -or, like melhor meaning better, have the same form for masculine and feminine.

  • O menino está contente! A menina está contente!
    Translation: The boy is content! The girl is content!
  • O menino é inteligente! A menina é inteligente!
    Translation: The boy is intelligent! The girl is intelligent!
  • O vestido é azul. A camisa é azul.
    Translation: The dress is blue. The shirt is blue.

Let’s see some more examples of all these cases below:

EndingMasculineFeminine
-a
o homem hipócrita
Translation: the hypocritical man
a mulher hipócrita
Translation: the hypocritical woman
-e
o treinador forte
Translation: the strong trainer
a treinadora forte
Translation: the strong trainer
-l
o exercício fácil
Translation: the easy exercise
a prova fácil
Translation: the easy test
-ar
o jogador peculiar
Translation: the peculiar player
a jogadora peculiar
Translation: the peculiar player
-s
o restaurante simples
Translation: the simple restaurant
a padaria simples
Translation: the simple bakery
-z

Translation: the happy boy
a moça feliz
Translation: the happy girl
-m
o pai jovem
Translation: the young father
a mãe jovem
Translation: the young mother
-or
o livro maior
Translation: the bigger book
a revista maior
Translation: the bigger magazine

Number of adjectives: singular vs. plural

In Brazilian Portuguese, the number (singular or plural) of an adjective will match the number of the noun it describes or modifies. Luckily, the rules for forming plural adjectives are the same ones you’ll follow to form the plural of nouns in Brazilian Portuguese. So, if you know how to make the plural form of nouns in Brazilian Portuguese, you basically already know how to make the plural of adjectives. Take a look at the examples below:

Ending
(Dictionary)
RuleMasculineFeminineEnglish
-o, -u, -ão, -a, -e

+ -s (usually)

bonito
bonitos
bonita
bonitas

beautiful

*-ês

+ -es meaning m.
+ -s meaning f.

-ar, -or

-l

legal

-s

no change

simples

Compound adjectives

Brazilian Portuguese compound adjectives — adjectives made up of more than one word — all follow one simple rule: only the last word within the compound adjective must agree in gender and number with the noun it modifies. For example:

SingularPlural
cabelo castanho-escuro
Translation: dark brown hair
cabelos castanho-escuros
Translation: dark brown hairs
olho verde-claro
Translation: light green eye
olhos verde-claros
Translation: light green eyes

Pretty simple, right? Now, we’ll take a quick look at where to place adjectives in Brazilian Portuguese — and then you’ll be ready for some practice!

Adjective placement: Where to put them in a sentence?

Unlike in English, adjectives in Brazilian Portuguese usually come after the noun:

nounadjective
a pessoa engraçada
Translation: the funny person
O restaurante brasileiro está cheio.
Translation: The Brazilian restaurant is full.

However, the adjective will sometimes come before the noun instead. Certain types of adjectives (e.g. possessive adjectives or demonstrative adjectives) will generally come before the noun, but with others, the placement will depend on your intended meaning or the emphasis you want to place. For example:

uma velha amiga
Translation: a long-time friend
uma amiga velha
Translation: a friend who is old

In summary

Let’s review what we’ve learned about adjectives in Brazilian Portuguese:

  • Adjectives must agree in gender and number with the nouns they are describing.

    • Gender agreement: most of the masculine adjectives end in -o and most of the feminine adjectives end in -a. Rules for creating feminine forms:

      • -u, -ês, and -or → add -a

      • -ão → change the ending to or -ona

      • -a, -e, -l, -ar, -s, -z, -m, -or (comparatives) → usually no change

    • Number agreement: the rules for number agreement of adjectives are the same as the rules for Brazilian Portuguese nouns.

  • Compound adjectives: we change only the last word in compound adjectives according to the number and gender of the noun.

  • Adjective placement: Brazilian Portuguese adjectives are typically placed after the noun. However, sometimes it is possible to place adjectives before the noun, depending on the meaning you want to give to the accompanied noun.
