This is by far the best book i have found for explaining spanish. Its content i will admit to be slightly boring, but if you have a real thirst of learning spanish then this book is for you.I think of spanish as a crossword puzzle that is covered in a thick blankett of dust. well this book is like a rag that removes the dust and reveals the puzzle. Now once you can see the entire puzzle then again this book helps link the intersectiong letters and helps you figure out other parts of the puzzle.I think that it makes it much easier to learn the language when you can see the entire puzzle, after all if you can see the puzzle then you can place the pieces and move them around until it works.So far this has been my number 1 book that i refer to for explanations and to get an ideal of what is happening to the words that im reading.this book is incredibly cheap for the value of the knowledge it can offer to someone. at the time i paid 6 bucks for mine.
