Can we make autocorrect not change words typed correctly

I love autocorrect but recently I've noticed the AI is becoming more and more prone to automatically change words even when i type them correctly. Even more annoying, is the way it doesn't warn you it even plans to change your text until the last letter when you're already confidently tapping your space bar. For example last night “resting” was replaced by “testing”. Im guessing this is an AI picking up on the frequency of the word test and trying to be overly clever by assuming now EVERYONE wants to type testing ALL of the time. Please get rid of this or tell me how to disable.
