Portuguese Letters: When Do You Capitalize?

The rules of capitalization for Portuguese letters are substantially different than for English. If you need to write a text in Portuguese for any reason, if you want it to look professional, you’ll need to learn these rules. Of course, besides knowing how to capitalize Portuguese letters, there are many other skills you’ll need to develop to produce high-quality Portuguese texts; working with a tutor will help you with this.

In this post, we’ll go through the various rules for capitalizing Portuguese letters, and we'll show how they differ from English.


In English, all letters in titles are capitalized except articles and prepositions. In Portuguese, only the first letter of the first word is capitalized, unless the title contains words which would normally start with a capital letter in plain text.

Proper Nouns (Names)

Proper nouns in Portuguese are capitalized in the same way as in English, that is, with a capital letter at the start of each word, except for prepositions such as de, which are not capitalized.

Robert, Peter, John

Roberto, Pedro, João

Abstract Nouns

In Portuguese, abstract nouns such as amor (love) and paz (peace) are often (but not always) capitalized, particularly when emphasis is required or they are central topics for the text in question. This does not usually happen in English (it can be found occasionally in classic literature).

One important concept for any democratic society is liberty.

Um conceito importante para qualquer sociedade democrática é a Liberdade.

Days of the Week and Months

In Portuguese, unlike in English, the days of the week and months are usually not capitalized.

Friday, Sunday, February, June Sexta-feira, domingo, fevereiro, junho


Conversely, the seasons are usually capitalized in Portuguese, whereas in English they are not.

Spring, summer, autumn, winter

Primavera, Verão, Outono, Inverno


Nationalities are not capitalized in Portuguese. Nacionalidades não são capitalizadas em português.
