IPA: //ʌnˈmɔːrəl//
KK: /ʌnˈmɔrəl/
Describing something that does not have moral qualities or is not influenced by moral considerations.
The actions of the character in the story were often seen as unmoral, lacking any sense of right or wrong.
Unmoral → It is formed from "un-" (meaning not) and "moral" (from Latin "moralis", meaning pertaining to manners or ethics). The word "unmoral" means not pertaining to or lacking in moral principles.
Think of 'not' ('un-') having to do with 'manners or ethics' ('moralis') — that's why unmoral means lacking moral principles.
