A behavior or action that is rude or disrespectful to others.

Incivility → It is formed from "in-" (meaning not) and "civility" (from Latin "civilitas", meaning citizenship or politeness). The word "incivility" refers to a lack of politeness or rudeness, indicating behavior that is not civil or courteous.
Think of 'not' ('in-') being added to 'civility', which means politeness. This helps you remember that incivility means a lack of politeness.
