When youre done fixing things, exit out and reboot the phone to load the new database into the keyboard.

For whichever input method is current, try clearing data for that 'app' in the applications manager. The mis-spelled word will be removed from the database.

You need to open an app feature that launches your keyboard so you can use predictive text, such as a new text or email message. Tap the switch next to Predictive to toggle it on. For example, when using Google Keyboard and entering a URL in Chrome, or a query in Google Search, no suggestions are offered because that's what the app specifies for those fields buy when using Swype, suggestions are alwasy offered because it ignores the apps' request to disable the suggestions. For iPhones and iPads, go to Settings > General > Keyboard.

When options (like word suggestions) are enabled, apps can allow/disallow them for each text field presented to the user, if the keyboard allows this.
