unhappened
Unhappened is a term used to describe events that were anticipated or expected to occur but ultimately did not. It refers to a potential future that was averted, prevented, or simply did not materialize. The concept can be applied in various contexts, from personal experiences to larger societal or historical scenarios. For instance, a planned meeting that is canceled before it takes place can be considered an unhappened event. Similarly, a natural disaster that was forecast but never struck a particular area is an unhappened event for that region.
In a more abstract sense, "unhappened" can also refer to possibilities that were considered but ultimately rejected
