In psychiatry, a new word or condensed combination of several words coined by a person to express a highly complex idea not readily understood by others; seen in schizophrenia, dementia and organic mental disorders.
A word coined by a patient who is in psychotherapy.
In psychiatry, invention of a new word that has meaning only to the person who coined it; it is normal in early childhood, but usually a sign of mental illness (e.g. schizophrenia) in an adult.
Fabricated words with meaning known only to the speaker; sometimes associated with schizophrenia or Tourette’s disorder.
The invention of words to which meanings are attached. It is common in childhood, but when it occurs in an adult it may be a symptom of a psychotic illness, such as schizophrenia. It should be distinguished from paraphasia, in which new meanings are attached to ordinary words.
The process of creating novel words that hold distinct significance for the creator is known as neologism. Additionally, the term neologism pertains to the newly invented word itself. In individuals with schizophrenia, consistent use of neologisms can be observed in their speech patterns.
