Did you know?

Immutable may describe something that is incapable of change, but the word itself—like all words—is mutable, both capable of and prone to alteration. To put a finer point on it, if language were fixed, we wouldn’t have immutable itself, which required a variety of mutations of the Latin verb mutare (“to change”) to reach our tongues (or pens, keyboards, or touchscreens—oh the many permutations of communication!). Other English words that can be traced back to mutare include mutate, transmute, and commute. Which reminds us—the mutability of language makes great food for thought during one’s commute.
