Well, maybe not so much language. What we call 'swear words' are Saxon(?) for ordinary things, but demonized because they are not the sanitized 'correct' Norman words e.g. fuck vs sexual intercourse, shit vs defecate and so on. That's pretty much displacing language? Certainly language got changed permanently.
