A word salad is a "confused or unintelligible mixture of seemingly random words and phrases", often used in psychiatry to describe a symptom of a neurological or mental disorder. The name schizophasia is used in particular to describe the confused language that may be evident in schizophrenia. The words may or may not be grammatically correct, but they are semantically confused to the point that the listener cannot extract any meaning from them. The term is also used in theoretical linguistics to describe a type of grammatical acceptability judgement by native speakers.
