How do I unlearn words? I just got the new Samsung Galaxy S5 and I was texting and I accidentally held down one of the words that pops up when I start texting and this box popped up saying that whatever word will be removed from learned words. So now every time I type the word "the" it changes it to their or them or anything similar and its really annoying. Because this is a new phone I have no idea where to go or what to look for. Please help!
Click on the right-arrow ">" at the top of the keyboard.  This will pull up a list of words.  Long press on a word and it will say "___ will be removed from learned words". Then press OK and it's gone!

Unless you are trying to remove an email address; then it doesn't disappear! :(  Really annoying.  Anyone know how to fix that?
