This book covers approximately 1,800 Japanese words in total, which 860 of them are explained with illustrations. It covers almost all Japanese words. The Book is classifying Japanese in the unique method.The consistent idea throughout the book is “there is a relationship between vocal sounds and meanings in Japanese language”. The principle of Japanese word generation is shown. The former linguistic theory of origin was a hypothesis. At the this book, vocabulary is classified on the basis of Japanese origin theory. It is useful actually, so the value of this thory will be demonstrated.
I spent a year searching for something like this and it exceeded my expectations. It is, in essence, a kind of dictionary, and yet I couldn't put it down. I honestly read every word, in just a few hours. They are all categorised by sound groups with clear explanations of how they relate, and I finally feel like I understand how this language works - vital when it is so foreign from English and other romance languages. I continue to feel that Japanese is so much more logical. This whole thing was fascinating.
