Root Explanation

Aggressor is formed from "ag-" (meaning to or toward) and "gradi" (meaning to step or walk). The word describes someone who steps toward another with hostile intent, hence an aggressor is a person who initiates an attack or hostile action.

Memory Tip

Think of someone 'stepping toward' ('gradi') another in a confrontational way ('ag-') — that’s why an aggressor is someone who attacks.
