1. General Overview


Nouns are words for naming persons, things, places and animals.
In Portuguese, a noun can be either masculine or feminine in gender and singular or plural in number.
It is very important to know the gender, otherwise you will not be able to speak the language correctly. The best way to learn the gender of a noun is to memorize it with its definite article.
In general nouns ending in –
o as in carro (car) or nouns referring to male persons like amig(male friend) or animals like gato (male cat) are masculine, and nouns ending in –as in casa (house) or nouns referring to female persons like amiga (female friend) or animals like gat
(female cat) are feminine.

12. Noun Suffixes


In Portuguese there are suffixes which can change the size of a noun.


13. Diminutive 


The diminutive is frequently used in Brazil. It is usually used to show a small version of something, but depending on the context, it is also used for emphasizing, expressing affection, irony and even in idiomatic expressions. It is particularly used usually when one talks to small children or refers to their things. 

The most common diminutive suffixes are –inho/inha and –zinho/zinha.

Diminutive suffixes can also be used with adjectives and adverbs. 


a mesa a mesinha the small table
o café o cafezinho the small coffee
barato baratinho very cheap
um pouco um pouquinho a little bit

14. Augmentative

The augmentative is less used than the diminutive and very seldom used in the plural form. It is usually used to show a large version of something, but sometimes it can also be used for emphasizing, expressing admiration or scorn.

The most common augmentative suffixes used in colloquial Portuguese are –ão/zão and –ona/zona.

Augmentative suffixes can also be used with adjectives.


um carro um carrão a car, a big car
uma mesa uma mesona a table, a big table
grande grandão/grandona big, huge
