“Word Salad: One of the most common symptoms of schizophrenia is a disturbance in the use of language. Rather than select words which make communication possible, schizophrenics may combine words in idiosyncratic ways, or use associations that are out of context. This tendency may generate a minor language disturbance; or, in extreme cases, a word salad in which the combination of words is unintelligible to the listener and so makes communication impossible.”
