IPA: /həˈræsər/
KK: /həˈræsər/
A person who bothers or annoys someone repeatedly, often in a way that causes distress or discomfort.
The company took action against the employee for being a harasser.
Harasser → It is formed from "harass" (from Old French *haracer*, meaning to set upon or attack) and "-er" (meaning a person who). A harasser is a person who attacks or bothers someone persistently.
Think of someone who 'attacks' or 'bothers' ('harass') another person — the '-er' just means a person who does that.
