It’s a dark night; you’re in an unfamiliar city, slightly lost, but pretty sure you’ll know where you are if you just get to the next corner. The streets are quiet. A stranger steps out of the gloom in front of you, and announces that certain words don’t mean what you think they mean. They’re words that you use but have never really felt comfortable with, words that you use mostly because you’ve heard them in set phrases, words like plethora.

Plethora, you wonder, could it be I’m using it wrong? That niggling uncertainty kicks in, the same niggling uncertainty that’s pushed you to educate yourself all these years. It creeps further, darkening your mind. Have I been using words wrong? Your breath quickens — how many others have thought heard me say them before this stranger came up and told me I was wrong? Have I used one of them lately? Have I been judged? Your pulse races. Did I just say one? — is, is that why this stranger materialized to announce it was wrong?

The stranger says more words are being used wrong, by others, by you. These words are more common, common enough to be known but not common enough to be well-known: myriad, enormity. Oh God, you think, I’ve used those words in business writing! The uncertainty changes into certainty, certainty that you are wrong, and worse, that people know it. Important people know it. That’s why you haven’t been promoted, it’s why your friends were laughing that one time and didn’t say why. The stranger has you now. The stranger knows the dark spots on your soul. The stranger is almost touching you now, so close, so close. Your eyes meet. The stranger’s eyes widen; this is it, the final revelation. Do you dare listen? You can’t listen, you must listen:

“And you’re using allow wrong, too!”

At which point the spell is broken — because c’mon, you’re not using allow wrong. You’d definitely have noticed that. You push the stranger out of the way, and realize your hotel’s just on the next block.

In the unfamiliar city of the Internet, I encountered such a stranger: Niamh Kinsella, writer of the listicle “14 words you’ve been using incorrectly this whole time“. Kinsella argues that your usage doesn’t fit with the true definition of these words, by which she usually means an early, obsolete, or technical meaning of the word.

Her first objection is to plethora, which she defines as “negative word meaning a glut of fluid”. And so it was in the 1500s, when it entered the language as a medical term. This medical meaning persists in the present day, but additional figurative meanings branched off of it long ago — so long ago, in fact, that one of the meanings branched off, flourished for 200 years, and still had enough time to fade into obsolescence by now. The extant figurative meaning, the one that most everyone means when they use plethora, is antedated to 1835 by the Oxford English Dictionary, at which point it was usually a bad thing (“suffering under a plethora of capital”, the OED quotes). But by 1882 we see the modern neutral usage: “a perfect plethora of white and twine-colored thick muslin”.

The second objection is to myriad, and here Kinsella deviates by ignoring the early usage. She hectors: “It’s an adjective meaning countless and infinite. As it’s an adjective, it’s actually incorrect to say myriad of.” But in fact myriad entered English as a noun, either as a transliteration of the Greek term for “ten thousand”, or as an extension of that very large number to mean “an unspecified very large number” (both forms are antedated by the OED to the same 1555 work). The adjectival form doesn’t actually appear until two centuries later, the 1700s. Both nominal and adjectival forms have been in use from their inception to the present day; claiming that one or the other is the only acceptable form is just silly.*

There’s no point in continuing this after the third objection, which is to using allow in cases that do not involve the explicit granting of permission. To give you an idea of what folly this is, think of replacements for allows in a supposedly objectionable sentence like “A functional smoke alarm allows me to sleep peacefully.” The first ones that come to my mind are lets, permits, gives me the ability, and enables. That’s the sign of a solid semantic shift; four of my top five phrasings of the sentence are all verbs of permission with the permission shifted to enablement. Kinsella herself has no beef with it when she isn’t aiming to object, judging by her lack of objection to an article headlined “Are we allowed optimism now?”.

This enablement usage isn’t new, either; the OED cites “His condition would not allow of his talking longer” from 1732. (Permit without permission is antedated even further back, to 1553.) This oughtn’t even to be up for debate; even if it were completely illogical — which, as an example of consistent semantic drift, it’s not — the fact that it is so standard in English means that it is, well, standard. It is part of English, and no amount of insisting that it oughtn’t to makes a difference. It’s similar to the occasional objection I see to Aren’t I?: even if I agreed it didn’t make sense, virtually every (non-Scottish/Irish) English speaker uses it in place of amn’t I?, so it’s right. End of discussion.

Why do we fall for this over and over again? Why do we let people tell us what language is and isn’t based on assertions that never have any references (Kinsella cites no dictionaries) and rarely hold up to cursory investigation? I don’t know, but my guess is that it appeals to that universal mixture of insecurity and vanity that churns inside each of us.

We are convinced that we must be doing everything wrong, or — and perhaps worse — that we’re doing most things right but there’s some unexpected subset of things that we have no idea we’re doing wrong. So if someone tells us we’re wrong, especially if they candy coat it by saying that it’s not our fault, that everyone’s wrong on this, well, we just assume that our insecurities were right — i.e, that we were wrong. But then, aware of this new secret knowledge, these 14 weird tricks of language use, our vanity kicks in. Now we get to be the ones to tell others they’re wrong. Knowing these shibboleths gives you the secret knowledge of the English Illuminati. Between our predisposition to believe we’re wrong, our desire to show others up by revealing they’re wrong, and our newfound membership in this elite brotherhood, what incentive do we have to find out that these rules are hogwash? All that comes out of skepticism is, well, this: me, sitting on my laptop, writing and rewriting while the sun creeps across a glorious sky on a beautiful day that I could have been spending on the patio of my favorite coffee shop, approaching my fellow patrons, dazzling them with my new conversation starter: “I bet you use plethora wrong. Allow me to explain.”

*: In fact, Kinsella undermines her own definition of “countless and infinite” in her supposedly correct example by using “countless and infinite” to describe the finite set of stars in the universe, so maybe she’s just in love with the sound of her own hectoring.
