# Feature: #97254 - Add Luxembourgish as supported language {#feature-97254}

See [forge#97254](https://forge.typo3.org/issues/97254)

## Description {#description}

TYPO3 now supports Luxembourgish out of the box.

Luxembourgish is one of the three administrative languages of Luxembourg
([https://en.wikipedia.org/wiki/Luxembourgish](https://en.wikipedia.org/wiki/Luxembourgish)).

The ISO 639-1 code for Luxembourgish is "lb", which is how TYPO3
is accessing the language internally.

## Impact {#impact}

It is now possible to

-   Fetch translated labels from translations.typo3.org / Crowdin automatically
    within the TYPO3 Backend
-   Switch the Backend Interface to Luxembourgish language
-   Create a new language in a site configuration using Luxembourgish
-   Create translation files with the "lb" prefix (such as `lb.locallang.xlf`)
    to create your own labels

and TYPO3 picks Luxembourgish as a language just like any other
supported language.
