English words that used to mean something else

Every word in a dictionary is a snapshot. Meanings move, sometimes slowly over centuries, sometimes within a lifetime, and some of the most ordinary English words have travelled a very long way. The journeys are not random, either: they follow a few recognisable patterns, and knowing them makes older English much easier to read.

Nice: from ignorant to pleasant

Nice comes through Old French from Latin nescius, "not knowing", built from ne- (not) and scire (to know). When it entered English in the Middle Ages it meant foolish or simple. Over the following centuries it drifted through a series of senses, including fussy, dainty, and precise or careful, before settling on "pleasant" around the eighteenth century.

The "precise" sense has not died. A nice distinction is a fine or subtle one, not a pleasant one, and nicety still means a small detail. Readers of Jane Austen will find Northanger Abbey (1817) poking fun at the newer meaning: one character teases the heroine for using nice to praise everything, which tells you the "pleasant" sense was already being overused two hundred years ago.

Silly: from blessed to foolish

Silly began as Old English sælig, meaning happy, fortunate or blessed. Its German cousin, selig, still means blessed or blissful. In English, the word slid step by step: blessed, then innocent, then harmless and deserving of pity, then feeble, and finally, by the late sixteenth century, foolish.

Each step is small and easy to follow. Someone innocent is easily taken advantage of; someone easily taken advantage of looks simple; someone simple looks foolish. That chain of small, reasonable shifts is how most dramatic changes happen.

Awful and awesome: one went down, one went up

Awful originally meant "full of awe": inspiring wonder, reverence or fear. God could be described as awful in a perfectly respectful sense. By the nineteenth century, the word had weakened into a general intensifier and then into simply "very bad".

Awesome began in almost the same place and for a long time meant much the same thing: overwhelming, awe-inspiring. In the late twentieth century, especially in American English, it went the opposite way and became a casual word of approval. Two words from the same root, one now meaning terrible and one meaning great.

Decimate: from one in ten to almost all

Latin decimare described a punishment used, rarely, in the Roman army: a unit judged guilty of mutiny or cowardice was divided into groups of ten, and one soldier in each group was killed. The word comes from decimus, "tenth".

In English, decimate has been used for centuries in the looser sense of destroying a large part of something: "the disease decimated the population". Some style guides still object to this, arguing it should only mean "reduce by a tenth". In practice, the looser meaning is the one you'll read almost everywhere, and the one dictionaries treat as standard. If you want to be exact about a proportion, it's clearer to say the number.

Egregious: from outstanding to outrageous

Egregious comes from Latin egregius, literally "standing out from the flock": e- (out of) plus grex, gregis (flock, herd), the same root you see in gregarious and congregate. In English it first meant distinguished or excellent, a compliment.

From the late sixteenth century it began to be used of things that stood out for being bad, and that sense took over completely. It is usually explained as ironic use hardening into the normal meaning. Today an egregious error is a shocking one, and nobody would take the word as praise.

Literally: the argument that isn't new

Literally means "in the literal sense, exactly as stated". It is also widely used as an intensifier, for things that are not literally true at all: "I literally died of embarrassment." This use annoys a lot of people, and it is also much older than most of them assume. Mark Twain wrote in The Adventures of Tom Sawyer (1876) that Tom was "literally rolling in wealth", and nineteenth-century writers used it the same way.

Major dictionaries now record the intensifying sense, usually with a note that it is informal and criticised. The practical advice for learners is simple: understand both meanings, and in formal writing, use it only when you mean it literally.

Words that got narrower

Some words did not change direction so much as shrink.

Words that went up or down in the world

Linguists call a shift toward a worse meaning pejoration, and a shift toward a better one amelioration. Both are common.

Why this matters when you read

Most of the time, a word's history is a curiosity. It becomes practical when you read anything more than a century or so old, because the older meaning can be sitting right there on the page and the sentence still makes sense with the modern one. A "nice" character in an older novel might be fussy rather than pleasant. An "awful" silence might be solemn rather than unpleasant. A "silly" shepherd in a sixteenth-century poem may be innocent rather than foolish.

A few habits help:

English will keep doing this. Some of the words you learn this year will mean something slightly different in fifty years, and that is part of what makes vocabulary worth paying attention to. Here is a routine for keeping the words you meet.
