Clear the learned words list

The BlackBerry Keyboard learns words and phrasing based on your usage to predict the next word you write. You can clear the word list used for word suggestions with the following steps:
  1. On the home screen, swipe down from the top of the screen.
  2. Tap Settings > Language and Input > Prediction and Correction.
  3. Tap Clear Learned Words.
Note: As you continue to type, the learned word list is regenerated unless you set the Learn New Words switch to Off on the Prediction and Correction screen.
