# Changing the language

Material for MkDocs supports internationalization (i18n) and provides
translations for template variables and labels in 40+ languages. Additionally,
search can be configured to use a language-specific stemmer (if available).

## Configuration

### Site language

### Site search language

[:octicons-file-code-24: Source][2] ·
:octicons-milestone-24: Default: _automatically set_

Some languages, like Arabic or Japanese, need dedicated stemmers for search to
work properly. Material for MkDocs relies on [lunr-languages][3] to provide this 
functionality. See the guide detailing how to [set up site search][4] for
more information.

### Directionality

[:octicons-file-code-24: Source][5] ·
:octicons-milestone-24: Default: _automatically set_

While many languages are read `ltr` (left-to-right), Material for MkDocs also
supports `rtl` (right-to-left) _directionality_ which is inferred from the
selected language, but can also be set with:

``` yaml
theme:
  direction: ltr
```

:material-cursor-default-click-outline: click on a tile to change the
directionality:

<div class="tx-switch">
  <button data-md-dir="ltr"><code>ltr</code></button>
  <button data-md-dir="rtl"><code>rtl</code></button>
</div>

<script>
  var buttons = document.querySelectorAll("button[data-md-dir]")
  buttons.forEach(function(button) {
    button.addEventListener("click", function() {
      var attr = this.getAttribute("data-md-dir")
      document.body.dir = attr
      var name = document.querySelector("#__code_1 code span:nth-child(5)")
      name.textContent = attr
    })
  })
</script>

## Customization

### Translations

[:octicons-file-code-24: Source][1] ·
:octicons-mortar-board-24: Difficulty: _easy_

If you want to customize some (or all) of the translations for your language,
you may follow the guide on [theme extension][6] and create a new partial in
`partials/language`, e.g. `en-custom.html`. Next, look up the translation you
want to change in the [base translation][1] and add it to the partial you just
created. Say, you want to change "__Table of contents__" to "__On this page__":

``` jinja
{% macro t(key) %}{{ {
  "toc.title": "On this page"
}[key] }}{% endmacro %}
```

Then, add the following lines to `mkdocs.yml`:

``` yaml
theme:
  language: en-custom
```
