IPA: /dɪsˈkɜːr.tə.si/
KK: /dɪsˈkɜr.tə.si/
An action or remark that is rude or disrespectful to others.
His discourtesy during the meeting upset many of his colleagues.
Discourtesy → It is formed from "dis-" (meaning apart or away) and "courtesy" (from Old French *courtoisie*, meaning politeness or graciousness). The word "discourtesy" means the absence of politeness or the act of being rude, indicating a departure from courteous behavior.
Think of 'dis-' meaning 'away' and 'courtesy' meaning 'politeness' — so discourtesy is when someone is away from being polite.
