Practical Korean Usage Pre-Intermediate 1

PRACTICAL KOREAN USAGE — PRE-INTERMEDIATE 1
Your AI-Powered Guide to Korean Grammar
by Sungtaek Lee (이성택)


Korean grammar is boring? That's only because you haven't read this book yet.

This is the book where your Korean stops being a list of separate sentences — and starts becoming a story.

You've conquered particles in Basic 1 and verb tenses in Basic 2. Now you learn the connectors that link one thought to the next: -고, -지만, -아/어서, -(으)니까, -(으)면, -(으)ㄹ 때, and more. These are the joints of natural Korean — the difference between sounding like a textbook and sounding like a real person. Call it the Book of Connection.

And it treats grammar the way grammar deserves: as drama, not drudgery.

WHY THIS BOOK IS DIFFERENT

🎬 Every rule has a story. Each connective ending arrives inside a K-Drama-worthy scene — never a dry chart.

🤖 Learn with AI. Built-in AI Companion challenges let you practice live with Claude, Gemini, or ChatGPT. Copy-and-paste prompts turn any chatbot into your personal Korean tutor.

🇰🇷 100% Hangul, zero romanization. From this level on, you read Korean as Korean — the fastest path to actually thinking in the language.

🎤 K-Culture on every page. K-Drama, K-Pop, cooking shows, and real-life situations anchor each grammar point to living Korean.

✍️ Write it by hand. Handwriting-practice sections move the patterns from your eyes into your fingers.

💙 A cast you'll root for. Follow 서준, 하은, and 민호 — and build your own Korean "sonnet" as you go.

HOW EACH CHAPTER FLOWS
A hook scene → the grammar core → drills → K-Culture → a mini-quiz → a sonnet.

WHO IT'S FOR
Learners who've finished a beginner course (or PKU Basic 1 & 2) and can handle basic particles and verb conjugation. If you can binge a K-drama for twelve hours straight, you can fall for Korean grammar too.

Part of the Practical Korean Usage (PKU) series — your AI-powered bridge from beginner to intermediate Korean.

Open the book. Start the adventure. 📖
