Practical Korean Usage Basic 1

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


Maybe it started with a song.

A melody you couldn't get out of your head — even though you didn't understand a word. A rooftop scene in a K-drama with the Seoul lights glowing behind it. A grandmother making kimchi the way her mother taught her. A fan chant that made you feel like you belonged to something bigger. Whatever brought you to Korean — that feeling was real, and it deserves more than subtitles.

So you downloaded an app. You learned 안녕하세요 and 감사합니다, collected streaks like trophies, and felt the thrill of catching a word in a drama for the first time. And then the thrill faded — not because you lost interest, but because the app taught you Korean WORDS without ever teaching you how Korean WORKS.

That's exactly where this book begins.

Practical Korean Usage: Basic 1 doesn't start with rules. It starts with you — and with the quiet engine behind every Korean sentence: particles. Those tiny tags (-이/가, -을/를, -은/는, -에, -에서, -의…) are the GPS of Korean: they tell a sentence who did what to whom. Master them, and scattered words finally snap into real, meaningful sentences.

WHY THIS BOOK IS DIFFERENT

🎬 Grammar wrapped in what you already love. Every chapter lives inside a K-culture theme — K-drama, K-pop, K-food, K-beauty, variety shows — because grammar sticks when it's attached to something you care about.

🤖 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.

🗣️ The Korean people actually use. Clear grammar charts, paired with the conversations you really hear — Hongdae cafés, KakaoTalk messages between friends, and your favorite shows.

🔤 Beginner-friendly, with romanization. Brand new to 한글? You're covered. Romanization supports you while you find your footing.

💙 A story you'll follow. Meet 서준, a Korean-studies student with more enthusiasm than ability, and his roommate 민호, who speaks Korean natively but explains it terribly — which somehow makes it MORE helpful. Their story grows chapter by chapter, and you'll write your very first Korean sentence along the way.

WHO IT'S FOR
Absolute and early beginners. If you know a few words from dramas and songs but still can't say what you actually mean, this book was written for you.

The free first volume of the Practical Korean Usage (PKU) series — your AI-powered guide from "I love Korean" to "wait, I can actually read this."

Your love for Korean isn't a distraction from learning. It IS the engine. Let's build on it. 📖
