VOCABULARY
The word "smog" was first coined in 1905 by one Dr H.A des Voeux of the Coal Smoke Abatement Society to describe the smoky fog, or "smog", prevalent in British cities. Smog is an example of a portmanteau word or "blend", when parts of two existing words are joined together to form a new one. Other examples include "staycation" (stay + vacation), and "phablet" (phone + tablet). The Economist has an interesting article on this linguistic phenomenon.
