Which of the following best describes tangentiality?

A. "Made up" words. This describes neologisms, where individuals create new, nonsensical words that have meaning only to them. It is often seen in schizophrenia and other psychotic disorders. B. Repeating of another's words. This describes echolalia, a speech disturbance where individuals involuntarily repeat words or phrases spoken by others. It is common in autism spectrum disorder, catatonia, and some neurological conditions. C. Thought of the speaker wanders off in another direction. Tangentiality occurs when a person's train of thought drifts away from the original topic and never returns to it. Unlike circumstantial speech, where the person eventually returns to the point, tangential thinking leads to incoherent, off-topic responses, commonly seen in schizophrenia, mania, and cognitive disorders. D. Meaningless rhythm of words. This describes word salad, where speech consists of random, disorganized, and nonsensical words without logical structure. It is a severe thought disorder seen in advanced schizophrenia or delirium.
