I think this is not the best option to know the meaning of any word beacuse if you want to know the meaning of any word in another language for ex. 'Hand'word meaning then you have to open this big book and find in 'H'category which takes a little bit time and also this book doesn't give the proper meaning of modern word, adult words and cool words like swag, ect. And my opinion is Instead of using this book you should use the google translate. It will help you in proper way.
