What is a noun and why nouns matter
In English, nouns name people, places, things, and ideas. The same is true in Portuguese, but nouns change form to show gender and number. Mastering nouns helps you form basic sentences, read signs, and understand simple conversations.
Example: casa means house; o livro means the book. Knowing the article with the noun is essential for correct grammar and natural sounding speech.
Gender: masculine and feminine
Portuguese nouns have gender: masculine or feminine. There is no neutral gender for most nouns. Articles and adjectives must agree with the noun’s gender.
Masculine definite article: o (the). Example:
o carro — the car
Feminine definite article: a (the). Example:
a casa — the house
Indefinite articles: um (a/an, masculine) and uma (a/an, feminine). Example:
um amigo — a (male) friend
uma amiga — a (female) friend
Beginner tips for gender
Many nouns follow common patterns that help predict gender, though there are exceptions. Learn these endings and practice with vocabulary lists.
Common masculine endings: -o, -r, -l, -n. Example:
o livro (book), o professor (teacher).
Common feminine endings: -a, -ção, -dade. Example:
a mesa (table), a canção (song), a cidade (city).
Number: singular and plural
Portuguese forms plurals in predictable ways. The article also changes to match plural nouns: o/os and a/as.
General plural rules:
If a noun ends in a vowel, add -s. Example:
a casa → as casas (the houses)
If a noun ends in a consonant, add -es. Example:
o hotel → os hotéis (the hotels)
If a noun ends in -m, change -m to -ns. Example:
o homem → os homens (the men)
Special endings: -ão can form plurals as -ões, -ães, or -ãos. These are irregular and must be learned case by case. Example:
o avião → os aviões (the airplanes)
Practical plural examples
o carro → os carros — the cars
a mão → as mãos — the hands
o lápis → os lápis — the pencils (unchanged)
Definite and indefinite articles
Articles are used more often in Portuguese than in English. In many contexts where English drops the article, Portuguese keeps it. This is important for natural speech.
Definite articles: o, a, os, as map to English the. Example:
Eu gosto do café. — I like the coffee. Notice do is de + o.
Indefinite articles: um, uma, uns, umas map to a/an/some. Example:
Eu quero um suco. — I want a juice.
Important note about contraction
Portuguese frequently contracts prepositions with articles. Learn the most common contractions: de + o = do, de + a = da, em + o = no, em + a = na. These appear in everyday speech.
Example:
Eu moro na cidade. — I live in the city.
O preço do ingresso é alto. — The ticket price is high.
Adjectives must agree with nouns
Adjectives change to match both gender and number of the noun they describe. For beginners, focus on common patterns.
Adjective ending in -o: change -o to -a for feminine and add -s for plural. Example:
o livro novo — the new book
a casa nova — the new house
os livros novos — the new books
Adjectives ending in -e or a consonant usually only change for number. Example:
um filme interessante — an interesting movie
dois filmes interessantes — two interesting movies
Useful adjective examples
grande — big:
a cidade grande — the big city
pequeno/pequena — small:
um cachorro pequeno — a small dog
