IPA: //ʌnˈbiːɪŋ//
KK: /ʌnˈbiːɪŋ/
Describing something that does not exist or is not present.
In a philosophical sense, unbeing refers to the state of non-existence.
Unbeing → It is formed from "un-" (meaning not) and "being" (from Old English "beon", meaning to exist or to be). The word "unbeing" refers to the state of not existing or not being.
Think of 'not' ('un-') combined with 'existing' ('being') — that's why unbeing means not existing.
