Removal of unwanted learned words

[AC Question]

How do I accomplish it on Samsung J2

 

[B. Diddy]

Welcome to Android Central! Go to Settings>Language & Input, and look for the Personal Dictionary option. That should let you delete learned words. Or if you start typing a word with the keyboard and you see a word in the prediction row, try long-pressing that word and see if it gives you an option to remove it.
