Circumstantial speech
Circumstantial speech (also referred to as circumstantiality) is the result of a non-linear thought pattern and occurs when the focus of a conversation drifts, but often comes back to the point. In circumstantiality, unnecessary details and irrelevant remarks cause a delay in getting to the point. If someone exhibits circumstantial speech during a conversation, they will often "talk the long way around" to their point, which can be seen in contrast to linear speech, which is direct, succinct, and to the point.
