Circumstantiality

Circumstantiality is a disrupted form of speech or writing in which the conversation is rambling and the person can't seem to get to the point because of irrelevant details and unnecessary comments. It's called circumstantiality because the speech is characterized by too many circumstances - too much detail, too much elaboration, and irrelevant topics. This is a symptom of schizophrenia and obsessive-compulsive disorder.
