IPA: /ɪˈmɔːrəl/
KK: /ɪˈmɔrəl/
Not conforming to accepted standards of right and wrong behavior.
Stealing is considered immoral by most societies.
Immoral is formed from "in-" (meaning not) and "moral" (from Latin "moralis", meaning pertaining to manners or ethics). The word describes behavior that is not in accordance with accepted standards of right or wrong.
Think of 'not' ('in-') following the rules of 'manners' ('moral') — that's why immoral means not following moral standards.
