1. Go to "Settings" and tap "Language & Keyboard".
2. Next open up the "User Dictionary".
4. You should be able to scroll through the alphabetical list and find the entry you want to edit or remove.
5. Tap the word you want to edit or remove, and then tap "Edit" or "Remove" from the pop-up menu.
6. The changes should save instantly.
NOTE: If you have a third-party keyboard installed on the tablet, you will see it listed in the Language & keyboard area also. If this is the case, instead of choosing "User Dictionary" from the menu, you will need to select the "Settings" listed below the name of the keyboard you're currently using.
