IPA: /ˈiːvəlˌduːɪŋ/
KK: /ˈivəlˌduɪŋ/
An act or behavior that is morally wrong or harmful, often associated with wickedness or crime.
The evildoing of the villain shocked the entire community.
Evildoing is formed from "evil" (from Old English "yfel", meaning bad or morally wrong) and "doing" (from Old English "don", meaning to perform or act). The word refers to the act of performing bad or morally wrong actions.
Think of 'evil' as something bad and 'doing' as performing an action — evildoing means performing bad actions.
