raving

The word "raving" originates from the Old French verb raver, meaning to dream or wander aimlessly, which evolved to signify speaking deliriously or irrationally. This French term likely stems from a Vulgar Latin root associated with roaming or being unsettled. The core semantic thread connects the ancient sense of mental wandering or being seized by a dream-like state to the modern meanings of wild, incoherent speech or behavior. The addition of the "-ing" suffix transforms the verb into an adjective or noun, describing the state or act of being in such a frenzied condition, and later, through hyperbolic informal use, an intensifier denoting extreme enthusiasm.
