First, thanks to Lauren for recommending this book!
The edition which I will be quoting from is by Perennial (an imprint of HarperCollinsPublishers) from 2001. I am somewhat familiar with Bill Bryson, as I once read his Neither Here nor There, an amusing account of his retracing, in midlife, his travels across Europe which he took as a young man. So, however informative The Mother Tongue turns out to be, I am sure to be entertained.
My interest in English is amateur, both in the sense that I am not paid to do anything with it (except, I suppose, speak it at work) and in the sense that I love the language. So I am looking forward to reading this book.
Note that I have used the label 'profanity' for this post, which means that at some point, I will use words considered profane. I will indicate at which point I do so; you have been warned.
