IPA: /dɪˈfɒɡə/
KK: /dɪˈfɔɡər/
A device or tool used to remove fog or condensation from a surface, typically found in vehicles to clear the windshield.
The defogger quickly cleared the fog from the car's windshield, improving visibility.
Defogger → It is formed from "de-" (meaning down or away) and "fog" (from Old English *fogga*, meaning mist or vapor) and the suffix "-er" (meaning one who). The word "defogger" refers to a device or person that removes fog or mist, effectively clearing visibility.
Think of 'removing' ('de-') 'fog' — that's what a defogger does, it helps clear away the mist.
