Lesson-by-Lesson Summary

Lessons 1--5: Foundations

Lesson Topic Key Point
1 Basic Sentence Structure SOV word order; 이다/아니다
2 Korean Particles (은/는, 이/가) Topic vs. subject markers
3 Object & Location Particles 을/를 (object), 에/에서 (location)
4 Verb Conjugation Basics Stem + ending; 해요체 formation
5 Adjectives (형용사) Descriptive verbs; adjective conjugation

Core principle from Lessons 1--5: Korean sentences end with the verb. Particles mark the grammatical role of each noun. Verbs and adjectives conjugate based on their stem's final vowel.

Lessons 6--10: Expanding Expression

Lesson Topic Key Point
6 Honorifics & Speech Levels 해요체 vs. 합쇼체; choosing formality
7 Past & Future Tense ~았/었어요 (past); ~(으)ㄹ 거예요 (future)
8 Negation 안 + verb; ~지 않다; 못 + verb; ~지 못하다
9 Connecting Sentences ~고 (and); ~지만 (but); ~(으)면 (if); ~아/어서 (because)
10 Wanting & Liking ~고 싶다 (want to); 좋아하다 (like)

Core principle from Lessons 6--10: Korean has multiple speech levels that must match the social context. Tense markers attach to the verb stem before the speech level ending. Sentences can be connected with conjunctive endings.

Lessons 11--15: Numbers, Time & Practical Skills

Lesson Topic Key Point
11 Sino-Korean Numbers 일, 이, 삼... for dates, money, phone numbers
12 Counters (수량사) Noun + Native Korean number + counter
13 Time Expressions Hours (Native Korean) + minutes (Sino-Korean)
14 Location & Directions 위/아래/옆/앞/뒤; ~에 있어요
15 Shopping & Money 얼마예요?; ~원; payment expressions

Core principle from Lessons 11--15: Korean uses two number systems. Native Korean numbers pair with counters and hours. Sino-Korean numbers are used for dates, money, minutes, and abstract counting.

Lessons 16--20: Grammar Depth

Lesson Topic Key Point
16 Can & Cannot ~(으)ㄹ 수 있다/없다; 잘 하다/못 하다
17 Progressive & Experience ~고 있다 (doing now); ~(으)ㄴ 적이 있다 (have done)
18 Giving & Receiving 주다/받다; ~아/어 주다 (do for someone)
19 Comparing 더/덜; ~보다 (than); 가장/제일 (most)
20 Expressing Opinions ~(으)ㄴ 것 같다 (I think); ~(으)ㄹ까요?

Core principle from Lessons 16--20: Korean expresses nuances like ability, ongoing actions, and opinions through verb endings and auxiliary constructions. These patterns stack onto the verb stem.

Lessons 21--25: Advanced Basics

Lesson Topic Key Point
21 Commands & Suggestions ~(으)세요 (please do); ~(으)ㅂ시다 / ~자 (let's)
22 Irregular Conjugations 7 types: ㅂ, ㄷ, ㅅ, ㄹ, 르, ㅎ, 으
23 Asking Questions Wh-words; ~(으)ㄹ까요?; indirect questions
24 Common Adverbs Frequency, degree, time, manner adverbs

What to Expect in Unit 2

Unit 2 builds on everything you have learned and introduces more complex grammar patterns and real-world communication skills:

Area Topics
Grammar Relative clauses (~는/은/을), quoted speech (~고 하다), conditional patterns (~(으)면, ~(으)ㄴ다면)
Verbs Compound verbs (~아/어 보다, ~아/어 놓다, ~아/어 버리다), passive and causative forms
Communication Making appointments, describing experiences in detail, expressing obligations (~아/어야 하다)
Vocabulary Expanded topic sets: health, travel, workplace, emotions
Culture Korean social norms in language use, age-based speech, business Korean basics

Tips for Success in Unit 2

  1. Review irregular verbs regularly. They appear constantly in natural Korean.
  2. Practice particles in context. Read Korean sentences and identify each particle's role.
  3. Listen actively. Watch Korean media and focus on the speech level being used.
  4. Write daily. Even 3--5 sentences per day builds muscle memory for grammar patterns.
  5. Speak out loud. Pronunciation and rhythm improve only through verbal practice.
