IPA: /ˈɡriːvəns/
KK: /ˈgrivəns/
A complaint or feeling of being treated unfairly, often leading to a formal protest or request for change.
She filed a grievance with the management about the unfair treatment at work.
Grievance → It is formed from "grieve" (from Old French *grever*, meaning to burden or oppress) and the suffix "-ance" (meaning the state or quality of). The word "grievance" refers to the state of being burdened or oppressed, often in the context of a complaint or injustice.
Think of feeling 'burdened' ('grieve') and the 'state' of that feeling ('-ance') — that's why a grievance is a complaint about being treated unfairly.
