IPA: /ɪmˈpoʊlɪtnəs/
KK: /ɪmˈpoʊlɪtnəs/
The quality or state of being rude or disrespectful to others.
His impoliteness during the meeting surprised everyone.
Impoliteness → It is formed from "im-" (meaning not) and "polite" (from Latin "politus", meaning polished or refined) and the suffix "-ness" (meaning the state of being). The word "impoliteness" refers to the state of not being polished or refined in manners, hence being rude or disrespectful.
Think of 'not' ('im-') being 'polished' ('polite') in behavior — that's why impoliteness means being rude.
