Nouns have three main grammatical characteristics, which, in most cases, determine what form they take: gender (masculine / feminine), number (singular / plural), and degree (augmentative / diminutive). In a sentence, they play either the role of the subject or object of a verb, that is, the thing which carries out or receives an action, respectively.
Gender
All nouns in Portuguese have either the masculine or feminine gender. Though there is sometimes a correlation, grammatical gender does not necessarily relate to social gender or biological sex. In most cases, masculine nouns end with an -o and feminine nouns end with an -a:
Masculine nouns:
- menino (boy); carro (car); sonho (dream); raio (lightning)
Feminine nouns:
- menina (girl); cama (bed); ideia (idea); chuva (rain)
There are also nouns that have different endings, but all of them are either masculine or feminine. There is no neutral gender in Portuguese.
Masculine noun examples:
- problema (problem); professor (teacher); herói (hero); lápis (pencil)
Feminine noun examples:
- mulher (woman); ré (defendant); análise (analysis); capitã (captain)
Number
All nouns in Portuguese are either singular or plural. The main ending for plural is adding “-s” at the end of the word.
menino (boy) — meninos (boys)
carro (car) — carros (cars)
menina (girl) — meninas (girls)
cama (bed) — camas (beds)
The plural form may also need more letters than just an “-s” at the end, and sometimes we even need to replace a few. These are just some examples:
coração (heart) — corações (hearts)
pão (bread) — pães (bread)
vendedor (salesman) — vendedores (salesmen)
sol (sun) — sóis (suns)
Degree
The degree indicates the size, intensity or value of a noun. Different from number and gender, the degree has a normal (or neutral) mode. The word will receive a new ending to indicate augmentative or diminutive modes.
