English grammar is often said to be over-complicated and difficult to get to grips with, but the truth is that, while there are certain rules that should be obeyed, the language evolves and develops over time and quite rightly so. In this book, Joseph Piercy outlines the 25 rules that should be adhered to in written and spoken English, defining the rules themselves and then decoding them for the layman so that he or she understands each rule and how it has been used and developed over time. In doing so, the author highlights the most common misuses or plain errors in the language, such as apostrophes, "who" and "whom," and avoiding split infinitives and double negatives, while also setting the reader on to the right path to speaking and writing in good, plain English.
