Is there a term for the acceptance of a made up term that then became the name of the object/idea/action once it was invented?
Example: Cyberspace. It was first used by William Gibson in his cyberpunk novels, but when actually invented, it now is widely used across the world (or at least across the United States).
Is there a term for this phenomenon?
I assume OP is asking about the process of becoming more widely used, not the actual coining of new words/expressions/meanings.
There’s also gaining acceptance, which I think is less commonly used. Personally I think this applies to a later stage in the process, when a neologism is subject to attacks from linguistic reactionaries seeking to preserve the “pure” language they grew up with.
Thanks to @Optimal Cynic for setting out the various stages in the process…
The original coinage is followed by awareness, currency, traction, acceptance, and finally ignorance (people forget or never knew it was once a neologism).
