KK: /grəˈveɪmən/
The most important or serious part of a complaint or accusation, especially in legal contexts.
The gravamen of her lawsuit was that the company had failed to provide a safe working environment.
Gravamen is formed from "gravis" (meaning heavy) and "-men" (a suffix used in legal terms). The word refers to the essential part of a complaint or grievance, emphasizing the weight or seriousness of the issue at hand.
Think of something that is 'heavy' ('gravis') in terms of importance or seriousness — that's why gravamen refers to the core of a complaint.
