LaTeX supports many worldwide languages by means of some special packages. In this article is explained how to import and use those packages to create documents in Portuguese.


Portuguese language has some accentuated words. For this reason the preamble of your file must be modified accordingly to support these characters and some other features.

There are two packages in this document related to the encoding and the special characters. These packages will be explained in the next sections.

Input encoding

Modern computer systems allow you to input letters of national alphabets directly from the keyboard. In order to handle a variety of input encodings used for different groups of languages and/or on different computer platforms LaTeX employs the inputenc package to set up input encoding. In this case the package properly displays characters in the Portuguese alphabet. To use this package add the next line to the preamble of your document:


The recommended input encoding is utf-8. You can use other encodings depending on your operating system.

Font encoding

To format LaTeX documents properly you should also choose a font encoding which supports specific characters for Portuguese language, this is accomplished by the fontenc package:


Even though the default encoding works well in Portuguese, using this specific encoding will avoid glitches with some specific characters, e.g., some accented characters might not be directly copyable from the generated PDF and instead are constructed using the base character and an overlayed shifted accent symbol, resulting in two separate symbols if you copy it. The default LaTeX encoding is OT1.

Language-specific packages and commands

To extended the default LaTeX capabilities, for proper hyphenation and translating the names of the document elements, import the babel package for the Portuguese language.


As you may see in the example at the introduction, instead of "abstract" and "Contents" the Portuguese words "Resumo" and "Conteúdo" are used.

If you need to use the Brazilian Portuguese localization use brazilian instead of portuguese as parameter when importing babel.

Sometimes for formatting reasons some words have to be broken up in syllables separated by a - (hyphen) to continue the word in a new line. For example, matemática could become mate-mática. The package babel, whose usage was described in the previous section, usually does a good job breaking up the words correctly, but if this is not the case you can use a couple of commands in your preamble.

 \hyphenation{mate-mática recu-perar}

The first command will import the package hyphenat and the second line is a list of space-separated words with defined hyphenation rules. On the other side, if you want a word not to be broken automatically, use the {\nobreak word} command within your document or include it in an \mbox{word}.
