Root Explanation

Concussion → It is formed from "con-" (meaning together) and "cussio" (from "quassare", meaning to shake or strike). The word describes the act of shaking or striking together, particularly in the context of a blow to the head that causes injury.

Memory Tip

Think of a strong 'shake' or 'strike' ('quassare') that happens 'together' ('con-') when someone experiences a concussion.
