In What’s Your Name?, readers are guided through the fascinating world of Han’gŭl, the Korean writing system, as a tool for transcribing names from any language with accuracy and elegance. The book explores Han’gŭl’s historical roots under King Sejong the Great, its modern versatility, and a speculative concept called "Multiverse Han’gŭl," imagining its evolution across cultures and dimensions. Alongside rich historical insights, the book includes interactive exercises, quizzes, and illustrations to help readers practice writing names and mastering pronunciation in languages such as English, French, German, Spanish, and Russian. Whether for self-study or classroom use, it’s a practical and creative journey into how language connects us.
