content: I first read and worked with this book on my own about 9 years ago and it really clarified grammar in a practical, "real life" way for me.It has helped me both as a writer and a reader.As a writer I found more options for expressing myself by having more tools to work with and as a reader it helps me decipher endlessly complex sentences that can resemble a linguistic maze.By being able to break down those complex sentences to their basic constituents, one can clearly see which parts of the sentence are functioning as core ideas, and which are functioning as embellishment.This book is very user friendly and is in my opinion an excellent self study guide with an interesting variety of exercises.Highly recommended
