An appreciation of “heresy”
To speak of the English language is to speak of something that’s less a tongue and more a sort of verbal headcheese. The simplest of concepts have dozens of terms to choose from, and even the source which prescripivists habitually cite only delays its assimilation of new phrases due to the constraints of researching etymology and printing new editions. Yet, both despite and as a symptom of this Charibdic state, there’s no simple and good phrase for describing when someone’s wrong about that which properly, descriptively, cannot be mistaken.
