What is the term for speech that includes unnecessary details with delays in reaching the main point?

The correct term for speech that includes unnecessary details and delays in reaching the main point is circumstantiality. This type of communication is characterized by excessive elaboration on minor details that may divert the speaker from the central topic, ultimately making it difficult to identify the main message. Circumstantiality can often be observed in individuals with certain mental health conditions, where their thought processes lead them to include irrelevant information before finally getting to the point.

In this context, the other terms have different meanings. Derailment refers to a pattern where the speaker's thoughts shift tangentially without any logical connection, causing disorganized and fragmented speech. Flight of ideas involves rapid shifts from one idea to another, typically seen in manic episodes, where thoughts are connected loosely but lack coherence. Incoherence refers to speech that lacks logical connections and is often nonsensical, making it challenging to understand. Each of these terms describes a different type of disorganization in speech, but circumstantiality specifically captures the essence of providing unnecessary details before arriving at the main point.
