but thats none of my business tho
My high school English teacher would not have accepted "language evolves" as an excuse for things like confusing "then" and "than" and not knowing the meaning of the word "literally".
Of course, words don't have universal meanings. Lawyers and scientists use the word "theory" differently, for example. In any given environment, you should use words the way the people you need to communicate with expect them to be used.
