Yes you can!
You can use up to five languages simultaneously. We’ve enhanced our multilingual support framework to make it even more effective, by constantly scanning input text to estimate which of the enabled languages are being used, and adjusting predictions accordingly.
To enable multiple languages please follow the below steps.
- Go into SwiftKey settings (either by tapping SwiftKey in your app list, or accessing the SwiftKey Hub from within the keyboard)
- Under settings tap 'Languages' and choose the desired languages to download from the list
- Your language will automatically be enabled
