Removing or replacing a standard autocorrect word.

[Windows Central Question]

I have a Nokia Lumia running 8.1. Every. Single. Time. I go to type "this" I either accidentally hit the "o" ("this" pops up above the "o" in suggested words) or hit "tho" (next to "this" in suggested words). I never use the word "tho," so I would like to remove it from my phones dictionary or make it so every time I type "tho" it is corrected to "this."

Problem is "tho" is a word that came on my phone, not one that I added to the dictionary so I have no idea how to get rid of it.

There isn't a way to edit the phone's dictionary.
