Asked a simple question, a patient produces a rapid stream of associated ideas — one word or image suggesting the next through rhyme, chance resemblance, or passing distraction — and after several minutes has still not addressed, or seemingly even registered, the original question at all. Before revealing the answer: is this circumstantiality?

No. The defining feature of circumstantiality — that the person does eventually arrive at the answer, however inefficiently — is absent here. This pattern, in which connections are driven by chance associations and the original goal is lost entirely rather than delayed, is much more consistent with flight of ideas. The distinction matters because circumstantiality retains an underlying organisation and goal-directedness that flight of ideas lacks, which carries different implications for the underlying process being considered.
