How can you change WhatsApp language?

To change the language of WhatsApp, you can follow these steps:

1. Open WhatsApp on your device.
2. Tap on the "Three-dot" menu icon in the top-right corner of the screen.
3. Tap on "Settings" from the drop-down menu.
4. Tap on "Chats" in the Settings menu.
5. Tap on "App Language" in the Chats menu.
6. Select the language that you want to use from the list of available languages.
7. WhatsApp will restart in the selected language.

Note that WhatsApp supports a wide range of languages, including English, Spanish, French, German, Italian, Chinese, Arabic, and many others. If you don't see your preferred language in the list, it's possible that WhatsApp does not support that language.

Additionally, changing the language of WhatsApp will only change the language of the app interface. It will not change the language of the messages that you receive or send. If you want to translate messages from other languages, you can use a third-party translation app or service.
