What is a moot point?

I can’t think of a time I’ve seen it used to mean anything other than “previously decided” or “debatable only as an academic exercise”. And yet I’ve recently been encountering people claiming that this is wrong, wrong, WRONG, and that moot in fact means quite the opposite: a point that is open for meaningful debate. A representative example of this claim from the recent “20 Common Grammar Mistakes that (Almost) Everyone Makes” article*:

Contrary to common misuse, ‘moot’ doesn’t imply something is superfluous. It means a subject is disputable or open to discussion. e.g., The idea that commercial zoning should be allowed in the residential neighborhood was a moot point for the council.”

Of course, if (almost) everyone misuses a word the same way, then it’s probably not a misuse. But setting that point aside, if moot really means the opposite of how it’s normally used, how could that have happened?

Let’s start the answer by noting that non-American English speakers might be wondering what I’m going on about. It seems that moot means something different depending on which side of the Atlantic it’s being used on. A little history: the OED reports that adjectival moot arose in legal parlance to describe hypothetical cases used as practice for law students. Thus the earliest meaning of moot referred to a debate without practical consequences, whether because the case was hypothetical or because it was a real case that had already been decided.**

Between the emergence of adjectival moot in the 1500s and modern times, its meaning spread out in two directions. One is that of American English: a point that is unrelated to law, is debatable, and whose debate has no practical consequences. Whether I should have been so enamored of The Juliana Theory’s “Into the Dark” when it was on heavy radio rotation in 2000 is a moot point, because I can’t go back and tell my younger self that the song was maudlin emo crap. But it’s also a debatable topic, because my interest in that song got me to seek out their album, which had better songs and which later led me to find out about a split EP containing Dawson High’s song “Port Matilda”, which had a huge influence on my artistic sensibilities throughout college. Points can be made on either side, but the decision can’t change.

The other direction in which moot spread was to a point that was just generally open for debate, whether or not it had practical consequences. This is what’s being claimed above to be the “correct” meaning, but here the author’s running afoul of our curious American tendency to confuse the British usage (which is what it is) for the correct usage. In my experience with American English, it’s at least the much less common meaning if not non-standard.

Of course, the two meanings are not very far apart. A point that some of the complainants overlook about the American meaning is that while the debate doesn’t matter, the point is still debatable. Sometimes it may not feel this way; Lynne Murphy cites an old Saturday Night Live sketch “The Question is Moot”, where Jesse Jackson is a game show host who repeatedly interrupts his contestants’ answers by declaring that the question is moot — i.e., unworthy of debate or speculation.

But this, crucially, does not mean that it could not be debated. It doesn’t work for points that are settled and beyond debate. Don’t these sentences sound strange?

(1a) ?Whether cats built the Sphinx is a moot point.
(1b) ?It’s a moot point whether Wayne’s World inspired Bridge Over the River Kwai.***

There is one sense of moot that I haven’t touched on yet. Looking through COCA, I found this example:

It shrank a bit, though its generous size should make the reduction moot.”

This seems to be a recently emerging meaning, for an undeniable but negligible matter. As far as I know, this is limited to predicative usages (e.g., the reduction was moot but not *the moot reduction). And maybe that’s what all this fuss is about, but I don’t think so.

Lastly, the word is moot, not mute. The standard pronunciation rhymes with boot. The pronunciation may be slowly moving toward mute, but at the moment, rhymes-with-boot is the dominant pronunciation in Standard American English.

**: If we consider the nominal moot as well, it goes back to Old English and could refer to a non-hypothetical court as well; a moot was any assembly of people, but especially one with judicial purposes. The OED notes that this usage persists, but I think it has to be restricted to British (or at least non-American) Englishes, because all the contemporary occurrences sound like nonsense to me.

***: In case you worry that the oddness of these sentences stems from the oddness of their topics, compare with That cats built the Sphinx is an idiotic notion, which sounds fine to me.
