Why do polite words keep going bad?

We invent a kind word to replace a harsh one, and within a generation the kind word has gone harsh too. There is a name for this: the euphemism treadmill.

Every so often a perfectly polite word quietly goes bad. Toilet was once a delicate way of not saying something blunter, and now it is the blunt thing itself, so we reach for bathroom or restroom instead. Give those a few decades and they will start to sound just as direct, and someone will invent the next gentle word to hide behind. We never seem to arrive. We just keep walking.

There is a name for this, and it is a good one.

The euphemism treadmill

The psychologist Steven Pinker named it in 1994: the euphemism treadmill. The pattern is simple and oddly relentless. We coin a gentle word to replace a harsh one, and the gentle word slowly soaks up the harshness of the very thing it names, until it is no kinder than the word it was meant to spare us. So we coin another. And another. We are walking hard, and the ground keeps sliding backward under our feet.

The endless queue for the same room

The clearest place to watch it is the smallest room in the house. Toilet began as the French toilette, a “little cloth,” the word for the act of washing and dressing. It was borrowed into English as a genteel way to gesture at the whole business, drifted to mean the dressing room, then the fixture, and finally became so plain that it needed replacing. In came lavatory, washroom, restroom, powder room, the loo, and the Victorian water closet. Every single one started life as a polite dodge. Half of them now need dodging themselves.

The saddest lap of all

The most sobering example is the language we use for human minds. In the early twentieth century, idiot, imbecile, and moron were not insults. They were technical medical classifications, and moron was deliberately coined around 1910, from the Greek moros, “dull,” precisely because doctors wanted a clean, neutral, clinical term.

Within a generation all three had become schoolyard taunts. The replacements that followed set off walking the same road, one after another. The words kept changing. The contempt underneath them did not. If you want proof that a feeling can outlast any number of the words we wrap around it, this is it.

Why the treadmill never stops

Here is Pinker’s real point, and it is more interesting than the lazy version, which is just that people have grown too sensitive. The bad feeling was never really living inside the word. It was living in how people felt about the thing the word pointed at. Change the label and you buy a few years of grace, but the old attitude soon seeps into the new word, because the attitude was never about spelling in the first place. Words are honest like that. They quietly end up reporting what we actually think, whatever we decide to call it.

Which is also why renaming is not the pointless fussing that cynics enjoy calling it. Each new word is a small act of care, an attempt to treat people a little better by speaking about them a little better. The treadmill does not prove the effort is silly. It proves something harder: that a kinder word is a beginning and only a beginning, because the word follows the feeling and never the other way around.

Words can climb, too

It is worth saying that the treadmill is not the only motion words make. Once in a while a word walks uphill instead. Nice began as the Latin nescius, “ignorant,” and spent centuries drifting through “foolish” and “fussy” before arriving at “pleasant.” Words also darken, sometimes dramatically: the German word for a present turned into the word for poison. Meaning is always in motion. The euphemism treadmill is simply the stretch of that road we build on purpose, and then keep having to rebuild.

So when a familiar polite word starts to sound rude, you are not imagining it, and you are not merely watching fashion. You are watching a word do its oldest job: telling the truth about what we feel, no matter what we agreed to name it. The real work, the words keep reminding us, is not to keep changing the name. It is to change our mind about the thing.
