Words That Turned Round: Idioms and Terms That Reversed Meaning Entirely

The comforting story about language is that it drifts. A word softens or hardens, widens or narrows, picks up a new shade here and loses one there, and we all keep up without noticing. That is true of most vocabulary most of the time. But a smaller and stranger class of words does something more violent: it turns round and faces the other way. The word that once meant one thing ends up meaning something close to its opposite, and speakers carry on using it as if nothing had happened. When you look these words up, the history is not a rumour. It is documented, dated, and quietly astonishing.

‘Nice’: from ignorant to agreeable

No English word has travelled further from its origins than nice. It comes, through Old French, from the Latin nescius, ‘ignorant, not-knowing’, literally ne- (‘not’) plus the stem of scire (‘to know’). When it entered English in the late thirteenth century it was an insult, applied to people who were foolish, ignorant or senseless. From there its career is a catalogue of swerves. By the fourteenth century it could mean ‘fussy’ or ‘fastidious’; around 1400 ‘dainty, delicate’; by the sixteenth century ‘precise, careful’ — a sense we still keep in the phrase a nice distinction. Only in 1769 is it recorded meaning ‘agreeable, delightful’, and not until around 1830 does it settle into ‘kind, thoughtful’.

So the modern compliment sits at the far end of a chain that began with an accusation of stupidity. The word was so thoroughly emptied of edge that by the early twentieth century the lexicographer H. W. Fowler could complain that it had become worn smooth by overuse. A single word, in other words, has meant ignorant, timid, fastidious, precise and pleasant — and the record lets us watch it move.

Writers noticed the drift while it was happening. In Jane Austen’s Northanger Abbey, written at the turn of the nineteenth century, Henry Tilney teases the heroine for calling a book ‘the nicest’, pretending to hear the older, narrower sense of ‘neat, precise’ and mocking the newer, vaguer one:

it is a very nice word indeed! — It does for everything.

The joke only works because both meanings were live at once: the exact sense Tilney affects to prefer, and the loose sense of general approval that had already begun to swallow it. Austen was, in effect, filing a contemporary report on a word mid-reversal.

‘Awful’ and ‘awesome’: one root, opposite fates

Split a word in two and you can sometimes watch each half walk off in a different direction. Awful and awesome share the noun awe, and both once meant, roughly, ‘inspiring awe’. To call a cathedral or a mountain awful was to praise it: it filled the beholder with reverent dread. The trouble is that awe itself carried both wonder and fear, and over time awful absorbed the fear while awesome kept the wonder. By the early nineteenth century awful had slid towards ‘very bad, frightful’, and then weakened further into a mere intensifier — an awful lot, awfully kind. The two descendants of one idea now sit on opposite benches: awesome is high praise, awful is a groan.

‘Egregious’: out of the herd

Some reversals seem to have been born of sarcasm. Egregious comes from the Latin egregius, literally ‘out of the flock’ (e-, ‘out of’, plus grex, ‘herd’), and it entered English in the sixteenth century meaning ‘distinguished, remarkably good’ — someone who stood out from the crowd for their excellence. Yet within a few decades it was also being used the other way. The Oxford English Dictionary records the laudatory sense in 1534 and a disparaging sense by 1573, and its editors suspect the flip was driven by ironic use: call a spectacular failure ‘egregious’ with a straight face often enough, and the sneer becomes the meaning. Today an egregious error is a conspicuously bad one, and the flattering sense is dead.

‘Silly’: the fall from blessedness

The gentlest reversal is also the saddest. Silly descends from Old English gesaelig, ‘happy, blessed’, a relative of the German selig, which still means ‘blessed’ today. In Middle English it passed through ‘holy’, ‘innocent’, ‘harmless’, then ‘pitiable’, ‘weak’, and finally, by the 1570s, ‘feeble in mind, foolish’. The path from blessed to foolish is a well-worn one across languages: words for innocence tend to curdle into words for naivety, because the guileless are so easily taken for the gullible. English pushed silly all the way down that slope while its German cousin stayed at the top.

The phrase that reversed its logic

Individual words are not the only things that turn round. Whole sayings can reverse, and the most quoted example is the exception proves the rule. People now deploy it to mean, absurdly, that an exception somehow confirms a rule it plainly breaks — as if a rainy day proved that it never rains. The original logic ran the other way. The maxim descends from a legal principle associated with Cicero, usually given as:

exceptio probat regulam in casibus non exceptis

— ‘the exception confirms the rule in cases not excepted’. The point is precise and useful: if a sign says ‘parking permitted on Sundays’, the very existence of that exception implies a background rule forbidding parking on the other six days. The stated exception reveals the unstated rule. Two things then went wrong in transmission. The crucial tail, in casibus non exceptis, dropped off; and the verb probare, which can mean ‘test’ as well as ‘prove’ or ‘confirm’, was flattened into the modern ‘prove’. What survives is a saying used, almost universally, to mean something its authors would not have recognised.

Why meanings turn round

These are not random accidents; they fall into patterns that linguists have named. When a word rises in dignity — nice from foolish to pleasant — the process is called amelioration. When it falls — silly, awful, egregious — it is pejoration. Irony is a repeat offender, hollowing out a word by praising bad things with good ones until the praise inverts. So is semantic weakening, the slow bleaching by which awful and terrible and terrific shed their force and become mere emphasis. And phrases mutate through simple wear: a clause falls away, a Latin verb is mistranslated, and a careful maxim becomes a lazy one.

One further pattern deserves naming, because it explains why reversals are so easy to miss. At the moment a word turns, both meanings coexist — as they did for nice in Austen’s hands and for egregious in the sixteenth century, when the same word could praise or damn depending on the speaker’s tone. For a generation or two the two senses live together, usually sorted by context, and speakers barely notice the tension. Then one sense quietly wins, the other slips into the past, and the reversal looks, in hindsight, like a clean switch. It never was. It was a long overlap that the winning meaning eventually swallowed.

What the reversed words really teach is humility about the present. We use nice and awful with total confidence, as though their meanings were fixed and obvious. They are neither. They are the temporary settlements of long arguments, and there is no reason to think the arguments are over. Somewhere in current speech a word is being used sarcastically, or softened, or narrowed, in a way that a dictionary three centuries hence will record as the moment it began to turn round.
