“Finding the right words is wisdom,
“It is intelligence to use that word properly.”

Language is more than just a means of communication; it is an important tool for organizing thoughts, expressing emotions, and connecting with the world.
Especially during adolescence, developing language skills is directly linked to developing the ability to think.

"Idioms for Teenagers 1" is a book designed to help teenagers develop a rich vocabulary and the ability to express themselves appropriately for different situations.
The author focused on four-character idioms that embody a long history and wisdom, and sought to reinterpret the profound meaning and lessons contained in just four characters in today's language.

This book is structured around three principles.
First, we introduced the exact meaning and origin of the idiom to help people understand the original meaning and historical background of the words.
Second, by providing specific examples that can be applied to situations that actual youth may experience, we aim to foster expression skills beyond simple knowledge acquisition.
Third, by incorporating world-renowned quotes and philosophical statements, it provides a profound language experience that blends the wisdom of the East and the West, past and present.

"Idioms for Teenagers" is not a simple reference book for memorization.
It is a guide to intellectual growth that helps young people think more clearly, express themselves more sophisticatedly, and engage in deeper conversations through the treasure of language called idioms.
Whether you're studying, having a conflict with a friend, feeling disappointed or wanting to give up, or wanting to share joy, the idioms in this book will serve as a guide to facing life firmly through the power of language.

The author said, “Idioms are words from the past, but their meaning is wisdom that is still valid for all of us living today,” and added, “I hope this book will be a good friend that helps young people develop their speech, thoughts, and hearts.”
