은/는 & 이에요/예요

By the end of this lesson you can:

• Attach the topic particle correctly: 은 after consonant-ending nouns, 는 after vowel-ending nouns.
• Say “is / am / are” in polite speech with 이에요 (after consonants) and 예요 (after vowels), including the question form and the negative 이/가 아니에요.
• Build complete identity sentences such as 저는 학생이에요 and 이름은 카미예요.

TOPIK 1 skills: Topic particle & copula (basic sentence grammar).

Your first grammar lesson: the topic particle and the copula. Every Korean sentence you’ve seen so far has used these. Now you’ll understand exactly why.

RECALL: You’ve been using these since Lesson 11. Every example sentence in Lessons 11–17 contained 은/는 and 이에요/예요. In L11 you saw 안녕하세요, 저는 카미예요 (“Hi, I’m Cami”). In L12 you saw 저는 학생이에요 (“I’m a student”). Today is the lesson where those patterns stop being mysterious and become fully understood. Grammar is not a separate subject from vocabulary. It’s the structure that holds your words together.

Part 1 · 은/는: The Topic Particle

은/는 does not mean “I”: it marks what the sentence is about

This is the most important thing to understand about 은/는: it is a topic marker, not a subject marker. It tells the listener “this is what we’re talking about now.” In English we don’t have a direct equivalent. We handle topics through word order and stress. Korean makes it explicit with a particle.

The particle attaches directly to the end of the topic noun. Which form you use depends on whether the noun ends in a consonant or a vowel.

Rule: 은 vs 는 (the consonant/vowel split)

• 은 attaches to nouns ending in a consonant (받침): 학생은, 한국은, 책은
• 는 attaches to nouns ending in a vowel (no 받침): 저는, 카미는, 나라는

The split exists entirely for pronunciation: 은 adds a syllable after a consonant to make it speakable; 는 attaches smoothly after vowels. The meaning is identical.

Topic vs. subject: why the difference matters

Korean has both a topic particle (은/는) and a subject particle (이/가, coming in Lesson 19). They are not interchangeable. 은/는 sets the frame for the whole conversation. 이/가 introduces new information. For now, the key insight is: when you say 저는, you are making yourself the topic (“speaking of me, here is something about me”).

TIP: 은/는 also signals contrast. When 은/는 is used in the middle of a sentence, it often carries a contrastive nuance: “this one (but not that one)”. 저는 좋아요 = As for me, it’s good (I like it). The topic particle is one of the most nuanced particles in Korean, but for TOPIK 1, the basic function of “marking the topic” covers 95% of what you need.

Exercise A · Particle selector: which form does each word take?

For each noun, decide whether it takes 은 or 는, then write the result. Worked example: 저 ends in a vowel (ㅓ) → add 는 → 저는 (jeo-neun).

1. 저
2. 선생님
3. 한국어
4. 책
5. 이름
6. 카미
7. 나라
8. 음식

Part 2 · 이에요/예요: The Copula

이에요/예요: “is / am / are” in polite speech

이에요 and 예요 are both forms of the polite copula: the verb “to be” used to link a subject/topic to a noun or predicate. They are identical in meaning; the form changes based on whether the preceding noun ends in a consonant or a vowel. Same rule as 은/는.

이에요 (i-e-yo). Use after nouns ending in a consonant (받침):

• 학생이에요 (hak-saeng-i-e-yo) · (I/you/they) am/are a student
• 한국 사람이에요 (han-guk sa-ram-i-e-yo) · (I am) Korean

예요 (ye-yo). Use after nouns ending in a vowel (no 받침):

• 카미예요 (ka-mi-ye-yo) · (I am) Cami
• 한국어예요 (han-gu-geo-ye-yo) · (It) is Korean

The question form: 이에요? / 예요?

To turn these into a question, simply raise your intonation at the end. Nothing changes in the spelling. 학생이에요? = Are you a student? 한국 사람이에요? = Are you Korean? The written question mark is often added for clarity, but the grammar is the same. Korean does not invert word order for questions the way English does.

Negation: 이에요/예요 → 이/가 아니에요

The negative of “is” is 아니에요 (a-ni-e-yo), meaning “is not.” The particle that attaches to the noun before 아니에요 is 이/가 (the subject particle from L19). For now, learn the pattern as a chunk:

• Positive: 저는 학생이에요 (I am a student)
• Negative: 저는 학생이 아니에요 (I am not a student)
• Positive: 이름은 카미예요 (My name is Cami)
• Negative: 이름은 카미가 아니에요 (My name is not Cami)

Part 3 · 단어: 15 Words for Identity & Introduction

오늘의 단어: Words that go with 은/는 and 이에요/예요. Today’s vocabulary is chosen to work directly with the grammar you’ve just learned. Every word here naturally appears in 저는 ___ 이에요/예요 sentences.

MILESTONE: 105 words in your active deck. You’ve crossed the 100-word threshold, a genuine landmark. More importantly, you now have grammar to hold those words together. Sentences are becoming possible.

Part 4 · 문장 만들기: Building Sentences

저는 ___ 이에요/예요: the template

The pattern 저는 [noun]이에요/예요 is the backbone of Korean self-introduction. It combines everything from this lesson: topic particle + copula. Look at how it scales from one word to a full introduction.

Pattern: [Topic]은/는 + [Noun]이에요/예요

[noun] + 은/는 + [noun/predicate] + 이에요/예요

1. 저는 카미예요. jeo-neun ka-mi-ye-yo I’m Cami.
2. 저는 학생이에요. jeo-neun hak-saeng-i-e-yo I’m a student.
3. 이름은 카미예요. i-reu-meun ka-mi-ye-yo My name is Cami.
4. 직업은 선생님이에요. ji-geo-beun seon-saeng-nim-i-e-yo My job is teacher.
5. 이것은 한국어예요. i-geo-seun han-gu-geo-ye-yo This is Korean.
6. 취미는 한국어 공부예요. chwi-mi-neun han-gu-geo gong-bu-ye-yo My hobby is studying Korean.
7. 저는 미국 사람이에요. 이름은 카미예요. 직업은 학생이에요. jeo-neun mi-guk sa-ram-i-e-yo. i-reu-meun ka-mi-ye-yo. ji-geo-beun hak-saeng-i-e-yo. I’m American. My name is Cami. I’m a student.

Part 5 · 연습: Fill in the Particle

Try to answer each one before checking the Answer Key at the end of the lesson.

1. 저___ 학생이에요. (저 ends in vowel ㅓ: which particle?)
2. 이름___ 뭐예요? (이름 ends in consonant ㅁ: which particle?)
3. 저는 회사원___. (회사원 ends in consonant ㄴ: which copula?)
4. 이것___ 음식이에요. (이것 ends in consonant ㅅ: which particle?)
5. 취미___ 뭐예요? (취미 ends in vowel ㅣ: which particle?)
6. 저는 의사___. (의사 ends in vowel ㅏ: which copula?)
7. 나라___ 어디예요? (나라 ends in vowel ㅏ: which particle?)
8. 제 친구___ 선생님이에요. (친구 ends in vowel ㅜ: which particle?)

CULTURE: 자기소개: The Korean Self-Introduction. 자기소개 (ja-gi-so-gae) means self-introduction: 자기 (self) + 소개 (introduction). In Korea, formal self-introductions follow a remarkably consistent structure: name, country, occupation or affiliation, and sometimes age. The grammar you learned today is the literal scaffolding of this ritual: 저는 [이름]이에요. [나라] 사람이에요. [직업]이에요. Korean culture places great emphasis on context and relationship: knowing someone’s occupation and approximate age helps establish the social register (how formally to speak to them). This is why the patterns in today’s lesson aren’t just grammar exercises. They’re the foundation of how Koreans place themselves in relation to others. 이름이 뭐예요? is never a neutral question: it’s the beginning of a social mapping.

Homework

1. Write your own 자기소개 (self-introduction) using today’s grammar: 저는 [이름]이에요/예요. 저는 [나라] 사람이에요. 직업은 [직업]이에요/예요. 취미는 [취미]예요. Say it aloud 5 times until it flows naturally.
2. Practice the 은/는 rule with 10 nouns from your vocabulary deck. Write each noun, identify whether it ends in a consonant or vowel, and write the particle form: e.g. 학생 → consonant ㅇ → 학생은.
3. Practice the 이에요/예요 rule with the same 10 nouns: e.g. 학생 → consonant ㅇ → 학생이에요. Then 카미 → vowel ㅣ → 카미예요. Write 5 full sentences.
4. Add today’s 15 words to your flashcard deck. Priority words for TOPIK 1: 학생, 선생님, 이름, 친구, 직업, 이것, 뭐, 저. These appear constantly in both reading and listening sections.
5. Lesson 19 preview: The subject particle 이/가, the complement to 은/는. Where 은/는 marks the topic, 이/가 marks the grammatical subject, especially when introducing new information. You’ll also learn 있어요/없어요 (there is / there isn’t), completing the basic predicate toolkit.
