Root Explanation

Hammerhead → The word is formed from "hammer" (from Old English "hamor", meaning a tool for striking) and "head" (from Old English "heafod", meaning the upper part of the body or an object). The term "hammerhead" refers to the distinctive shape of the head of a hammer, which is used for striking.

Memory Tip

Think of a 'tool for striking' ('hammer') and the 'upper part' ('head') of that tool — that's why a hammerhead is the part of the hammer that strikes.
