iPhone Keyboard Dictionary

I’ve looked everywhere for an answer for this. My keyboard autocorrects to German. I am a native English speaker and English is not only the only keyboard I have, but it is also the iPhone’s language. I’ve reset my keyboard’s dictionary more times than I can count. I had an iPhone SE 2020 from March of 2021 until about a week ago and I figured the problem would stop once I got a new phone (iPhone 13). Does anyone have any tips? I can’t find anything that I haven’t already tried.
