Don't Mistake the Meaning of Misnomer

What’s in a name? Well, in some cases, a name will contain an error, a misunderstanding, or a mislabeling. Historians have long noted that the Holy Roman Empire was not holy, nor Roman, nor an empire. The Battle of Bunker Hill was actually fought on Breed’s Hill. And the Pennsylvania Dutch are in fact of German ancestry. For such cases, we have the term misnomer, which can refer both to the use of an incorrect or inappropriate designation (as in “it’s a misnomer to call an orca a ‘killer whale’”) or to the designation itself. Regardless, there’s no mistaking the source of misnomer: it comes from the Anglo-French verb mesnomer (“to misname”) and ultimately has its roots in nomen, the Latin word for “name.”
