Is there a word for a vocabulary associated with a particular work of fiction?

In his Lord of the Rings, J.R.R. Tolkien coins the word "glitter" to be a collective noun for elves.

In his books about Wonderland, Louis Carol invents an absolute mountain of words, words like "frabjous," meaning "great, wonderful, fabulous," and "boojum," meaning an especially dangerous variety of "snark," another invented word.

In Star Wars, we have terms like "tie fighter," a kind of spacecraft, and lightsaber, a kind of weapon.

Harry Potter, Star Trek, A Song of Fire and Ice (A Game of Thrones), Battlestar Galactica, Stargate, The Chronicles of Narnia... And the list goes on. These are all similar examples of works that incorporate their own subset of English words, some entirely original and some that alter standard English definitions.

Given that there are so many authors that do this in their works, is there any word that means a special set of words whose definitions are specific to and used by a specific work or works, particularly fiction?

Solution 1:

Perhaps
- Argot or - Jargon

See this StackExchange discussion of Argot and Jargon: https://linguistics.stackexchange.com/questions/2812/argot-vs-jargon

Solution 2:

You may be referring to a lexicon:

A stock of terms used in a particular profession, subject, or style; a vocabulary: the lexicon of surrealist art.

(Linguistics) a list of terms relating to a particular subject

(Linguistics) the vocabulary of a language or of an individual

Solution 3:

A neologism is a new word coined by an author or a group of people that either catches on and becomes part of everyone's vocabulary or does not.
