General english vocabulary building
I have used this book for general vocabulary building. This book is nicely arranged in chapters according to relevance. This was the first book I picked to start with my vocabulary enhancement. I felt I have got the right book as it gave me interesting method to look at words. I was engrossed in learning with this book for many days. Now this book acts as a reference for me when in doubt.
Etmological method of learning new words
This book provides a etmological method, means a method where we learn the root of the words first, the source of the wordlet, and then try to learn many words having the same root. When this book is taken as an exercise book instead of as a novel it work best. The reader is required to invest time and go through this book on a regular basis to learn efficiently.
