It means fog Answer: It is combination of the words SMoke and fOG. It was first used in London England. It was caused by the smoke, sulfur dioxide and ash from the coal burning fireplaces common in England combining with the frequent, and famous, British fogs. The word has been appplied to the mre common photochemical smog now present in many cities caused by hydrocarbon vapour and NOx reacting in the presence of sunlight.
