Other reviewers have asked the question 'Who is this book for?' and that was the question going through my mind as I read it. The juxtaposition of trivia and detailed grammatical explanations is bizarre. The book attempts to be humorous but does not really succeed. This is not a book for someone who wishes to learn Latin as the grammatical explanations given are totally inadequate. Neither is it a book for someone who wishes to obtain a theoretical overview of how Latin works without actually learning the language. A reader who does not wish to learn Latin itself but wishes to learn the meaning of a few common Latin words and phrases would be advised to look elsewhere, such as James Morwood's Dictionary of Latin Words and Phrases, which despite its title, can be read from cover to cover, in small chunks, quite comfortably. Neither would I recommend this book as a refresher for the person who has already learned Latin (which is the reason I read it) as it is too lightweight.
I recognise that certain parts of this book may appeal to individuals who possess a particular type of 'schoolboy' humour, but such individuals (of which the author, presumably, is one) are not likely to be numerous. My general feeling at the end of the book was that I was very disappointed and that I had wasted my time, though fortunately not my money as I had borrowed it from my local public library.
