Your iPhone or iPad will usually come pre-installed with the keyboard set in your regional language. But if you can't find it, or if you want to add a new keyboard language, here's how to change the keyboard on your iPhone or iPad.
How to add a new keyboard language to your iPhone or iPad
Let's start by adding a new language keyboard to your iPhone or iPad.
Open the "Settings" app, then go to the "General" section.
Select the "Keyboard" option.
Now click on the "Keyboard" button.
You will see a list of all available keyboards. Click here on the option "Add new keyboard".
Scroll through the list of available keyboards and press the language you want to add.
You will now see it in the keyboard list. To rearrange the list or remove a language from the list, press the "Edit" button in the upper right corner.
Touch and drag the Handle icon next to a keyboard to rearrange it.
To remove a keyboard, press the Minus (-) button, and then press “Delete. "
How to switch between keyboard on iPhone and iPad
Now that the new language keyboard has been added to your iPhone or iPad, let's switch to it. Go to a text entry page and then tap a text box to bring up the keyboard.
Touch and hold the Globe icon in the lower left corner of the screen. (If you are using an older iPhone with a Home button or iPad, the Globe icon will appear in the last row of the keyboard.)
 You will now see a list of all available keyboards. Look for the newly added language keyboard, and then tap it to change the language.
You can also quickly browse all available keyboards by tapping the Globe icon.  All that's left is to start typing with the new keyboard language!
If you're running iOS 13 or higher on your iPhone, try the new sweep keyboard feature to type faster with one hand.
