What is the difference between cant and jargon, or assume and presume? What is a fandango? How do you spell supersede? Is it hippy or hippie?

These questions really matter to Bill Bryson.

Here is a very personal selection of spellings and usages, covering such head-scratchers as capitalization, plurals, abbreviations and foreign names and phrases. Bryson also gives us the difference between British and American usages, and miscellaneous pieces of essential information you never knew you needed, like the names of all the Oxford colleges, or the correct spelling of Brobdingnag.

An indispensable companion to all those who write, work with the written word, or who just enjoy getting things right, it gives rulings that are both authoritative and commonsense, all in Bryson's own inimitably goodhumoured way.
