Why is the predictive text changing correctly spelled words to different ones?

[AC Question]

I have set my phone to predictive text in the idea it would make texting easier. It in fact changes correctly spelled words to non words? Or makes it a word Im not trying to say. Such as the word pee will change to pre after hitting space. Whyyyyyy?!!??!?! So ANNOYING

I get the same issue occasionally, I've come to accept it's from the software on most of our phones being designed in Asia by people who don't speak English as their first language.

There are plenty of 3rd party keyboards available on the play store, some are better than others.
