Root Explanation

Foghorn → The word is formed from "fog" (from Old English *fogga*, meaning a thick mist or vapor) and "horn" (from Old English *horn*, meaning a hard, pointed projection). A foghorn is a horn that produces sound in foggy conditions to warn ships of hazards.

Memory Tip

Think of a 'thick mist' ('fog') and a 'pointed projection' that makes noise ('horn') — that's why a foghorn is used to signal in foggy weather.
