IPA: //nɒnˈhæpənɪŋ//
KK: /nɑnˈhæpənɪŋ/
A situation or event that fails to take place; something that is expected to happen but does not.
The meeting was a nonhappening, as no one showed up.
Nonhappening → It is formed from "non-" (meaning not) and "happening" (from the verb "happen", which comes from Middle English *hapnen*, meaning to occur or take place). The word "nonhappening" refers to something that does not occur or take place.
Think of 'non-' meaning 'not' and 'happening' meaning 'occurring' — so nonhappening means something that is not occurring.
