logomachy

It doesn't take much to start people arguing about words, but there's no quarrel about the origin of logomachy. It comes from the Greek roots logos, meaning "word" or "speech," and machesthai, meaning "to fight," and it entered English in the mid-1500s. If you're a word enthusiast, you probably know that logos is the root of many English words (monologue, neologism, logic, and most words ending in -logy, for example), but what about other derivatives of machesthai? Actually, this is a tough one even for word whizzes. Only a few very rare English words come from machesthai. Here are two of them: heresimach ("an active opponent of heresy and heretics") and naumachia ("an ancient Roman spectacle representing a naval battle").
