Inaccurate spellcheck in iOS 17 on iPhone 16 Pro

"Inaccurate spellcheck in iOS 17 on iPhone 16 Pro: I just bought a new iPhone 16 Pro and the spellcheck is so inaccurate. It’s almost like it doesn’t understand English. It throws up words that don’t make sense, it has terrible, terrible grammar and vocabulary. It’s not even worth having.. I have no way of changing it other than looking in my settings to see if I can turn it off completely. If there’s a way to turn it off completely will someone tell me please."
