What are neologisms?

Neologisms are defined as the creation of new words that are not recognized within the standard language, often lacking clear meaning or context that others can understand. This definition aligns with the answer provided, as neologisms can emerge from individuals seeking to describe experiences or concepts for which no existing term suffices, especially in the context of certain psychological conditions such as schizophrenia.

While new vocabulary can indeed be created and used appropriately, neologisms go beyond this by specifically focusing on words that do not have established meaning in the language. Therefore, while new and appropriate vocabulary (which may be seen in technical jargon or slang) is valuable in communication, the essence of neologisms is about the novelty and lack of conventional recognition in language.
