Okay so I have been searching for a good hour on how to update or add words to my iPhone's dictionary and I haven't really come up with anything. Most of what I found is stuff from a year or 2 ago and it doesn't work anymore. The other method of typing into Safari and then into Notes isn't really what I am looking for either. If it turns out that is what I have to do then fine but I am just looking for a solution that will allow me add words so that my phone doesn't try to autocorrect or underline words that I don't want it to.

On my quest I did find a keyboard directory I can access through iFile but I'm not entirely sure that what I want. I saw a word in there that I added through the Safari method and it still underlines it.
