What is the term for a form of paraphasia where a person creates non-words that sound like they could be real words?

The correct term for a form of paraphasia where a person creates non-words that sound like they could be real words is neologism. In the context of communication disorders, neologism refers to the production of new words that are not recognized by the language or do not have a defined meaning within the linguistic community. For example, a person might combine sounds or syllables to form a word that seems plausible but is not an actual word in the language. This phenomenon is often observed in individuals with certain types of aphasia, particularly Wernicke's aphasia, where the fluency of speech remains but the content becomes nonsensical or devoid of semantic meaning.

When analyzing other terms, jargon refers to speech that may be grammatically correct but is nonsensical or filled with excessive terminology that lacks clarity. Paraphasia is a broader term for speech errors that involve substitutions, omissions, or additions of words, which may include both real words and non-words. Logorrhea describes an excessive flow of words, often with little to no coherence or relevance to the conversation. Each of these concepts addresses different aspects of speech abnormalities, but neologism specifically emphasizes the creation of new, yet nonsensical, words.
