'이에요 / 예요' - Your First Korean Sentence

저는 학생이에요. I am a student.

Key point If the last syllable of the noun has a final consonant (batchim - the consonant at the bottom of a syllable), use 이에요. If it ends in a vowel, use 예요. The meaning is the same: "is / am / are."

How to use it

Korean doesn't use a separate verb like "am" or "is" here. You attach 이에요 or 예요 directly to the end of a noun: 학생 (student) becomes 학생이에요 (= is a student).

Which one you attach depends only on sound. If the noun's last syllable ends in a consonant - a batchim - the noun needs 이에요. If it ends in a vowel, it needs 예요. English does the same thing with a and an: you say an apple but a banana. The sound decides for you before you can think about it. A useful way to remember it: the extra 이 works much like the extra "n" in "an." It keeps two vowel sounds from running together.

At a glance

Noun	Last syllable ends in…	Result
학생 (student)	consonant ㅇ - batchim	학생이에요
선생님 (teacher)	consonant ㅁ - batchim	선생님이에요
물 (water)	consonant ㄹ - batchim	물이에요
친구 (friend)	vowel - no batchim	친구예요
의사 (doctor)	vowel - no batchim	의사예요
학교 (school)	vowel - no batchim	학교예요

Not sure whether a syllable has a batchim? Look underneath the vowel. 생 has a letter sitting under the vowel - that's the batchim. 사 has nothing underneath - no batchim.

Examples

저는 마이클이에요. I'm Michael. - 마이클 ends in ㄹ (batchim), so 이에요.

이분은 제 친구예요. This is my friend. - 친구 ends in a vowel, so 예요.

이거는 물이에요? Is this water? - Same form for a question; only the rising tone changes, and 물 keeps 이에요.

Common mistakes

❌ 제 친구이에요. → ⭕ 제 친구예요. 친구 ends in a vowel, so 이에요 is one syllable too many. This is one of the most common spelling errors beginners make - in writing it stands out immediately.

❌ 저는 선생님예요. → ⭕ 저는 선생님이에요. 선생님 ends in ㅁ (batchim), so it needs the full 이에요. Without 이, the word is hard to pronounce - if it's hard to say, that's your clue.

Fill in each blank with 이에요 or 예요. Just check the batchim.

💡 Study tip - Say it out loud, not in your head. The rule exists to make speech smooth, so your mouth will pick it up faster than your eyes will. From now on, every time you learn a new noun, attach 이에요 or 예요 right away and say the full sentence once.
