This is literally the first word that comes to mind for many people, when asked what word or usage is most vexatious. The bothersome sense is the one we define as “in effect; virtually —used in an exaggerated way to emphasize a statement or description that is not literally true or possible.”
We do not offer this definition as a practical joke, or because we want to hurt you; we are trying to provide an accurate record of the English language, as it is used. If you wish to read more about this you may do so here.
What is the point of words having meanings if they can mean literally the opposite of what they are defined to mean? People who use the word litterally to mean not literally aren't using an alternative meaning, they're using the word incorrectly. MW seems intent on ensuring that no matter how wrong you are you're still right.
