The best book for beginners starting to learn French!

French is a 'global language' that is used as an official language in over 40 countries around the world, including France and the European continent.
As the world becomes increasingly interconnected, I believe there will be more and more opportunities for anyone to learn and use French, regardless of their reasons for learning it.
This book is structured as a textbook that focuses on speaking and listening, with a condensed explanation of grammar. It also includes detailed explanations of conversational expressions, especially considering the difficulties faced by independent learners.
And conversational expressions are presented gradually, considering the level of difficulty and frequency of use, and are connected to enable repeated learning.
Additionally, you can increase the efficiency of your learning by watching video lectures provided for free.
