Unoccurred

Unoccurred is an adjective used to describe something that has not happened or taken place. It signifies an event or situation that has failed to materialize, often in contrast to an expectation or possibility. The term implies a lack of occurrence or realization.

The word is formed by adding the prefix "un-" to the past participle of the verb "occur," meaning to happen or take place. Therefore, "unoccurred" literally means "not occurred." It is typically used in contexts where there was a potential for something to happen, but it did not.

For example, one might say that a predicted disaster remained unoccurred, or that a planned meeting was unoccurred due to unforeseen circumstances. The adjective can also be used to refer to something that was never intended to happen but also didn't. In essence, unoccurred denotes the absence of an event that could have, or perhaps was expected to, take place.

While not as commonly used as some other negative adverbs or adjectives, "unoccurred" serves a specific purpose in conveying the non-happening of a particular event. Its usage emphasizes the lack of realization or occurrence of something that was within the realm of possibility or expectation.
