IPA: /nɒnˈaɪdɛntɪti/
KK: /nɑnˈaɪdənti/
The state of being different or not the same as something else.
The concept of nonidentity is important in philosophy when discussing individuality.
Nonidentity → It is formed from "non-" (meaning not) and "identity" (from Latin "identitas", meaning sameness or oneness). The word "nonidentity" refers to the state of not being identical or the absence of sameness.
Think of 'not' ('non-') being combined with 'sameness' ('identity') to remember that 'nonidentity' means the absence of sameness.
