How do I fix my auto correct on iPhone?

My phone often changes the word he to heather. I checked under text replacement and there’s nothing there. Is it predictive text instead? And if that’s the case is there anyway to fix this one prediction without turning the whole thing off? I enjoy having predictive text for the most part it’s mainly just this one super common pronoun that is crazy annoying to deal with.
