🎤Pronunciation
🌳Etymology
Origin
The word 'smog' was coined in 1905 by a London physician as a portmanteau of 'smoke' and 'fog' to describe the severe air pollution plaguing industrial-era London. It emerged during the height of the Industrial Revolution as a term specifically addressing the visible atmospheric hazard created by industrial emissions mixing with natural fog.
Breakdown
smoke + fog = smog. The word combines the first morpheme of 'smoke' (combustion particles and gases) with 'fog' (water vapor and moisture), creating a blended word (portmanteau) that describes the hybrid phenomenon of polluted mist.
