How to change Language in Facebook back to English
When you create a Facebook account, its UI appears in the same language as the one you choose in your device’s language settings. However, you can change it to a different language and once its purpose is met, you can change the language on Facebook back to English. The process is very easy and straightforward. When you change the language in Facebook, you invariably change your language and region settings to see things such as buttons, notifications, most text, and tooltips in a different language and format. So, to get started, open your Facebook account (web version) and click the drop-down menu in the upper-right corner of your Facebook Feed.
Next, select the second option from the top, visible as the cog-wheel icon. This will open the Settings & Privacy section of your Facebook account.
Then, choose the last option (seen as a globe icon) to open the Language section. When directed to a new page, click the Blue link under the First heading to open the languages list.
Hit the drop-down button and choose the English language. When done, hit the Blue button below the language to save the changes.
The changes will be applied instantly and change the Facebook language back to English. Read: How to change Outlook.com Language back to English
What happens when Facebook is in another language?
Changing the language settings for your Facebook account won’t change your computer, phone or tablet settings. So, if you change your Facebook language settings on one device, it won’t change the settings on another device.
Is Facebook available in different languages?
Yes! Facebook offers its 2.3 billion users features such as menus and prompts in 111 different languages, deemed to be officially supported. It also tries to keep up with a flood of new languages that come up due to the large-scale penetration of mobile phones in every corner of the globe.
