What does confabulatory mean?
Confabulatory is an adjective describing something relating to confabulation — most commonly, the unintentional fabrication of plausible-sounding but false memories or narratives. In neurology and psychiatry, a confabulatory response is one in which a patient, often someone with amnesia or Korsakoff syndrome, sincerely fills gaps in memory with invented details, without any intent to deceive. This clinical sense dominates contemporary usage and gives the word a formal, technical register. A secondary, older sense describes a person or exchange as chatty or conversational, deriving from the same Latin root as 'confabulate' in its original meaning of talking together informally. The word is valuable precisely because it distinguishes honest invention from deliberate lying: a confabulatory speaker believes what they are saying. Writers on memory, medicine, and psychology rely on it to name this curious phenomenon where the mind's storytelling outruns its record-keeping.

A confabulatory patient isn't lying — the brain is sincerely filling memory gaps with fiction it fully believes.

Etymology of confabulatory
Confabulatory derives from the Latin verb fabulari, meaning 'to talk' or 'to converse', itself from fabula ('a tale' or 'story'), the root of English 'fable'. It came into English through the Late Latin verb confabulari, 'to talk together', which also yields the verb confabulate and noun confabulation. The word entered English usage alongside those relatives, with its clinical sense of fabricating false memories developing in nineteenth- and twentieth-century medical writing.
How confabulatory is actually used
The dominant modern sense is clinical and technical, appearing in neurology, psychiatry, and cognitive science to describe speech or narratives produced by patients with memory disorders such as Korsakoff syndrome. The older, lighter sense meaning 'chatty' or 'conversational' survives mainly in literary or humorous writing. The word carries a formal register in both senses.
