Os Adjetivos

Portuguese adjectives agree with the noun they describe in gender (masculine or feminine) and number (singular or plural). They almost always sit after the noun, with a few important exceptions.

The agreement rules are the same logic as Spanish or Italian: change the ending to match the noun. The position rules are slightly different from English (where adjectives always go before): in Portuguese they go after, except in a small but frequent set of cases.

Agreement — gender and number

-o / -a adjectives

Most Portuguese adjectives follow the -o (masculine) / -a (feminine) pattern:

Examples:

o menino bom — a casa boa — os meninos bons — as casas boas o carro novo — a mesa nova — os carros novos — as mesas novas

-e adjectives — invariable for gender

Adjectives ending in -e don’t change for gender, only for number:

o homem inteligente / a mulher inteligente (same form) os homens inteligentes / as mulheres inteligentes (plural adds -s)

Consonant endings — usually invariable for gender

Many adjectives ending in consonants don’t have a separate feminine form:

o céu azul / a porta azul (no -a added) os céus azuis / as portas azuis (plural irregular: azul → azuis)

-ês / -ês / -ês / -or — gender-marked

A few endings DO take a feminine form:

Nationality adjectives

Most nationality adjectives follow -o / -a, but several have unique forms:

• português / portuguesa (Portuguese)
• espanhol / espanhola (Spanish)
• francês / francesa (French)
• alemão / alemã (German)
• inglês / inglesa (English)

Position — usually after the noun

The Portuguese default is adjective after noun:

uma casa pequena — a small house um livro interessante — an interesting book um carro vermelho — a red car

This is the opposite of English. Small house, but casa pequena.

Adjectives that USUALLY go before the noun

A small set commonly sits before the noun:

• bom / mau (good / bad)
• grande (when meaning “great”, not “big”)
• pequeno (sometimes)
• outro (other)
• mesmo (same / -self)
• próprio (own)
• algum, qualquer, todo, cada (some, any, every, each)

um bom amigo — a good friend uma má ideia — a bad idea uma grande mulher — a great woman (not “a big woman”) o mesmo dia — the same day a minha própria casa — my own house outro problema — another problem

These are common enough that you’ll see them constantly.

Adjectives that change meaning by position

This is where Portuguese gets subtle. A few adjectives have different meanings depending on whether they sit before or after the noun:

Examples:

uma grande mulher — a great woman uma mulher grande — a large/tall woman

um pobre homem — a pitiable man um homem pobre — a poor (financially) man

um velho amigo — an old friend (long-known) um amigo velho — an aged friend

o próprio rei — the king himself a roupa própria — the proper clothing

This is one of the most expressive features of Portuguese. Choosing position is choosing meaning.

Multiple adjectives

When two or more adjectives modify the same noun, you have options:

After the noun, joined by e (and)

um livro interessante e útil — an interesting and useful book uma casa pequena e bonita — a small and pretty house

One before, one after

uma boa casa nova — a good new house o velho amigo francês — the old French friend

Both after, comma-separated

uma rapariga alta, inteligente e simpática — a tall, intelligent, friendly girl

Demonstrative and possessive — also agree

Demonstratives and possessives agree with the noun like regular adjectives:

este livro / esta mesa / estes livros / estas mesas o meu livro / a minha mesa / os meus livros / as minhas mesas

In European Portuguese, possessives take the definite article (o meu); in Brazilian, often without (meu).

Comparative and superlative

For comparing things, the basic patterns:

• More X than: mais X (do) que — mais alto do que
• Less X than: menos X (do) que — menos rápido do que
• As X as: tão X como / tão X quanto — tão alto como
• The most X: o/a mais X — o mais inteligente
• The least X: o/a menos X

See comparativo-e-superlativo for the full treatment.

What you don’t need to do

You don’t need to put every adjective before the noun like English. The default is after.

You don’t need to add -a to every -e adjective. Inteligente doesn’t have a separate feminine form.

You don’t need to memorise every position rule. Read enough Portuguese and you’ll feel where adjectives sit.

Common confusions

• Adjectives go AFTER the noun by default. Casa pequena, not pequena casa.
• Bom, mau, grande, pequeno often go BEFORE for non-physical meaning. Um bom amigo, uma má ideia, uma grande mulher.
• Position changes meaning for grande, pobre, velho, próprio. Be careful.
• -e adjectives don’t change for gender. Inteligente, grande, forte, triste — same form for both.
• Adjectives agree in number even when invariable for gender. Azul (singular both genders) → azuis (plural).
• EP uses the article before possessives, BP often doesn’t. O meu carro (EP) vs. meu carro (BP).

Where you’ll meet it in the library

Adjectives are in every Portuguese sentence:

• Pinóquio (A1+) — Storica’s adaptation introduces basic agreement (menino curioso, Fada azul, gato preto) and pre/post-position contrast (uma grande aventura).
• Madame Bovary (B2+) — Flaubert’s Portuguese rendering uses adjectives to build Emma’s inner world. Jovem bonita, casa pequena, lugar aborrecido, marido medíocre — each adjective placed for psychological precision.
• O Retrato de Dorian Gray (B2+) — Wilde’s Portuguese chains adjectives in series (homem belo, jovem e cruel), uses pre-position adjectives for moral judgment (o próprio Dorian), and shifts position to shift meaning.
