IPA: /ˈwaɪldfaɪər/
KK: /ˈwaɪldˌfaɪər/
A large and uncontrolled fire that spreads quickly through forests, grasslands, or other areas, often caused by natural events like lightning or human activities.
The wildfire destroyed thousands of acres of forest and forced many people to evacuate their homes.
Wildfire is formed from "wild" (from Old English *wild*, meaning untamed or uncontrolled) and "fire" (from Old English *fyr*, meaning flame or blaze). The word describes a fire that is uncontrolled and spreads rapidly in a natural environment.
Think of something that is 'untamed' ('wild') and 'burning' ('fire') — that's why wildfire refers to an uncontrolled fire in nature.
