Other forms: fabulations
A fabulation is a made-up story or a lie, especially a far-fetched one. If you break a window and blame it on your badly behaved pet rabbit, everyone will know right away it’s a fabulation, so don’t even try.
The noun fabulation is related to the verb fabulate, meaning "to tell a tall tale," from the Latin root fabula, meaning "a story or tale." Realistic fiction that includes dreamlike or fantastic elements as if they were real is also called fabulation. And in psychiatry, fabulation is a symptom of mental illness in which a person tells stories they’ve invented but believe are true. In all these cases, the stories are far-fetched and unreal, but told as if they are or could be true.
