A newly coined word or phrase, or an existing word given a new meaning — and the process that keeps a language from being a museum.
// Where it sits
Words do not become real at a point on this line. They simply move along it.
What it really means
The word for making new words was itself, for a long time, an accusation.
When neologism entered English in 1772, it frequently carried a disapproving edge. To neologise was to be affected — to invent vocabulary in order to seem clever, rather than because the language had a gap. The complaint that new words are a degradation is therefore older than most of the words people now defend against newer ones.
Which is the useful thing to know about this entry, because it explains the shape of an argument that recurs every year.
The standing question is when does a word become real? — and the answer people reach for is the dictionary.
That gets the relationship backwards. Dictionaries record; they do not authorise. A lexicographer's job is to document that a word is being used widely and durably enough to need explaining to someone who encounters it. That is a report on what has already happened. By the time a word is added, it has typically been in use for years, sometimes decades — which is why dictionary announcements always feel slightly late, and are.
The bar is not popularity. It is durability: sustained evidence across varied sources over time. Which is why some extremely loud words never make it — they arrived, saturated everything for eight months, and vanished — and some quiet ones do.
So a word does not become real at a point. It moves along a line, from nobody saying it to everybody saying it, and no position on that line is the threshold. The dictionary entry is a marker placed after the fact, at a point a committee judged safe.
And the obvious thing, which is worth stating because it settles most arguments about this: every word in English was a neologism. Dictionary was one. Neologism was one. The words the objectors are defending were, at some point, the words somebody else was objecting to.
Where it comes from
Recorded in English from 1772 (the narrower sense 'a new word' from 1803), and originally often derogatory — coining new words was treated as an affectation before it was treated as a normal linguistic process.
Myths & misconceptions
A word isn't real until a dictionary adds it.
Dictionaries RECORD usage; they do not authorise it. A lexicographer's job is to document that a word is being used widely and durably enough to need explaining. The word was real the entire time people were using it, which is why dictionary additions always lag by years.
Neologisms are a modern degradation of the language.
Every word in English was a neologism at some point, and the term itself was long used as a CRITICISM — coining new words was treated as an affectation. The complaint is older than most of the words the complainers defend.
Compare & contrast
Neologism vs slang
A neologism is new; slang is informal. They overlap heavily but are different axes — a technical term coined last year is a neologism and not slang, and a slang word two centuries old is slang and not a neologism.

Questions people ask
- Who decides if a word is 'real'?
- Nobody. Dictionaries record words that are being used widely and durably enough to need explaining — which is documentation, not authorisation. A word is in use before it is in a dictionary, always.
- How do new words get in?
- Lexicographers monitor evidence of sustained use across varied sources over time. The bar is durability rather than popularity, which is why some very loud words never make it and some quiet ones do.
- Was 'neologism' ever an insult?
- Yes. In its earlier English use it frequently carried a disapproving edge — coining new words was treated as an affectation rather than as a normal feature of a living language.
