If the whole world is using "cola" as a word to describe your "pepsi" and you are (maybe even rightly so!) convinced they are literally different things here is a free tip:

It is up to you to convince the people that the difference is big enough that they should want to change their language. And you know how to make sure they won't want to do that? Speak down to them, paint them as stupid for not knowing and so on.

This feels more like a banana/plantain scenario.
