Simple and Compound Adjectives

Adjectives are words that describe or qualify nouns. They can be adjetivos simplessimple adjectives if they’re just one word, or adjetivos compostoscompound adjectives if formed by two or more elements, usually (but not always) connected by a hyphen (-).

Simple Portuguese Adjectives

Um carro bonitoA beautiful car

Compound Portuguese Adjectives

Gender and Number Agreement

Although there are some that only have one gender form, for the most part, simple adjectives must match the gender and number of the noun they’re describing:

Compound adjectives, however, are a bit more complicated. Only the second element changes according to number and gender:

Notice that in both sentences, only the -americano element of the compound adjective is adjusted to match the gender and number (americanos, americana). The latino- element remains unchanged.

Exceptions

As always, there are a few exceptions:

  • Adjectives that end with a noun, which are mainly colours, don’t change at all. For example, the adjectives verde-azeitonaolive green and amarelo-douradogolden yellow stay as they are.
  • A few compound adjectives, despite not having a noun as its second element, are also invariable. Two examples are azul-marinhonavy blue and azul-celestesky-blue
  • Both elements change in the expression surdo-mudodeaf mute , so that it becomes surdos-mudos (masculine, plural) and surdas-mudas (feminine, plural).

Compound Adjectives with no Hyphen (-)

There are many adjectives that combine two words or elements without needing to be hyphenated. Examples include:

Even though these are considered compound, they each form just one word, so they usually follow the same rules as simple adjectives, matching the noun in gender and number. One exception would be the adjective ultravioletaultraviolet , which is invariable.
