Usage Note

Frequently appears in discussions of language change, technology, and popular culture rather than in everyday conversation. The term is a countable noun; one may speak of 'a neologism' or 'neologisms' in general. The verb 'neologize' exists but is rare — most English speakers say 'coin a new word' instead.

Common Mistakes

I learned a new neologism today.
I learned a new word today.
'Neologism' already includes the idea of newness, so adding 'new' is redundant.
This neologism word appears in the dictionary.
This neologism appears in the dictionary.
'Neologism' already means a word or phrase; adding 'word' is unnecessary.

Sense: noun/1

All four terms refer to words that did not previously exist in a language, but they differ in scope and register. 'Neologism' is the broadest and most neutral term, covering newly created words, borrowed terms, and existing words that take on new meanings. 'Coinage' is slightly more formal and often implies a deliberate act of invention, sometimes with a known inventor. 'New word' is the everyday equivalent — less technical and more conversational. 'Made-up word' carries an informal, sometimes dismissive tone, suggesting the word was invented on the spot or lacks legitimacy. 'Portmanteau' is a narrower category of neologism formed by blending two existing words, like 'brunch' (breakfast + lunch) or 'spork' (spoon + fork). If you are writing an academic essay on language change, use 'neologism' or 'coinage'; if you are chatting with friends about slang, 'new word' or 'made-up word' sounds more natural.

Etymology

GreekFrenchEnglish

Borrowed from French 'néologisme', which was formed from the Greek roots 'néos' (νέος) meaning 'new' and 'lógos' (λόγος) meaning 'word, speech', plus the suffix '-ism'. The word entered English in the late 18th century, around 1772, and was first used to describe new religious terms before broadening to cover any newly coined word or expression.
