IPA: /nɒnɪɡˈzɪstəns/
KK: /nɑnɪɡˈzɪstəns/
The state or condition of not being present or not existing.
The concept of nonexistence can be difficult to understand.
Nonexistence → It is formed from "non-" (meaning not) and "existence" (from Latin "existere", meaning to stand out or to be). The word "nonexistence" refers to the state of not existing or being absent.
Think of 'not' ('non-') combined with 'being' ('existence') to remember that 'nonexistence' means the state of not being.
