To open the Language and Region Settings menu, navigate to the desktop Facebook website and then click the down arrow in the top-right of the screen. In this drop-down menu, select “Settings” or “Settings & Privacy”.

In the sidebar on the left, select “Language and Region.” If you’re using the Facebook redesign, click the “Privacy” option from the pop-up menu. To change the language of Facebook’s interface for your account, click the “Edit” button to the right of the “Facebook Language” option.

Click the first drop-down menu, and select the language you want to use for all Facebook buttons, titles, menus, etc. If you select a language that hasn’t been fully implemented across all Facebook apps, a second drop-down menu will appear.

Using this menu, you can select a secondary language that Facebook will use if your first choice is not available. When you’re finished, select “Save Changes”.
