Definition, synonyms and related words
An instance of something occurring; an event or happening.
"The occurrence was so sudden that no one had time to react."
In plain English: There is no noun form of occurring because it is only used as a verb meaning something that happens.
"The occurrence of rain delayed our picnic plans today."
Usage: Use the noun form only when referring to a specific instance or event, as it is rarely used independently without further clarification like "an occurrence." In most everyday contexts, simply using the verb phrase "something occurring" or the synonym "event" conveys your meaning more clearly than this awkward nominalization.
