IPA: /ʌnˈlaɪknəs/
KK: /ʌnˈlaɪknəs/
The state of being different or not similar to something else.
The unlikeness between the two paintings made it clear that they were created by different artists.
Unlikeness → It is formed from "un-" (meaning not) and "likeness" (from Old English "licnes", meaning similarity or resemblance). The word "unlikeness" means the state of not being similar or different from something else.
Think of 'not' ('un-') being added to 'similarity' ('likeness') — this helps you remember that 'unlikeness' refers to the absence of similarity.
