Korean Sentence Order: Topic vs. Subject Markers in Simple Sentences
Learn how Korean sentences are ordered and when to use 은/는 versus 이/가. Build simple subject-verb-object statements and ask staff questions with confidence.
By TheaFirst conversations · Yapr Learn
Korean sentences typically follow a subject-object-verb order, but the more important distinction for beginners is the difference between the topic marker 은/는 and the subject marker 이/가. This lesson gives you a direct answer: 은/는 marks what the sentence is about (the topic), while 이/가 marks the grammatical subject, often introducing new information or focusing on who or what does the action. You will practice simple declarative sentences like 'I eat an apple' and learn to ask staff simple questions using these markers.
By the end, you can…
- identify and use the topic marker 은/는 and subject marker 이/가 in simple Korean sentences.
- construct basic subject-object-verb statements about everyday actions.
Listen once. Try it slowly. Then say it without looking.

저는 사과를 먹어요.
I eat an apple. (As for me, I eat an apple.)
jeo-neun sa-gwa-reul meo-geo-yo.
Uses 은/는 to mark 'I' as the topic. The object 사과를 comes before the verb 먹어요.
제가 사과를 먹어요.
I eat an apple. (It is I who eats an apple.)
je-ga sa-gwa-reul meo-geo-yo.
Uses 이/가 to mark 'I' as the subject, often answering 'Who eats an apple?' or introducing new information.
이거 뭐예요?
What is this?
i-geo mwo-ye-yo?
A simple question to ask staff about an item. No topic or subject marker needed here.
물 주세요.
Please give me water.
mul ju-se-yo.
A polite request. The object 물 is followed by the verb 주세요. No marker is required in this fixed expression.
화장실이 어디예요?
Where is the restroom?
hwa-jang-sil-i eo-di-ye-yo?
Uses 이/가 to mark 화장실 as the subject of the question. Useful for asking staff for directions.

Useful pattern
Korean sentences usually end with the verb. A common pattern is Subject + Object + Verb. For example, 저는 사과를 먹어요 (I eat an apple). Here, 저는 is the topic ('as for me'), 사과를 is the object, and 먹어요 is the verb. You can replace the subject and object: 제가 물을 마셔요 (I drink water). The particle 를 marks the object when it ends in a vowel, and 을 after a consonant. The verb always comes last.
When to use it
Use 은/는 when you want to say 'as for...' or when the subject is already known from context. Use 이/가 when you are introducing new information or emphasizing who did something. For example, if someone asks 'Who ate the apple?' you answer 제가 먹었어요 (I ate it), using 이/가. If you are simply stating what you do, you can say 저는 사과를 먹어요. Both can be correct; the choice depends on what you want to focus on. In questions to staff, 이/가 often appears: 이게 뭐예요? (What is this?) uses 이게 (이것이) with 가.
Listen to each line, then take one part and reply out loud.
저는 커피를 마셔요. 그쪽은요?
I drink coffee. How about you?jeo-neun keo-pi-reul ma-syeo-yo. geu-jjok-eun-yo?저는 차를 마셔요. 그런데 이게 뭐예요?
I drink tea. By the way, what is this?jeo-neun cha-reul ma-syeo-yo. geu-reon-de i-ge mwo-ye-yo?그건 한국 차예요. 물 드릴까요?
That is Korean tea. Shall I give you water?geu-geon han-guk cha-ye-yo. mul deu-ril-kka-yo?네, 물 주세요. 감사합니다.
Yes, please give me water. Thank you.ne, mul ju-se-yo. gam-sa-ham-ni-da.A little context goes a long way
In Korean, the choice between 은/는 and 이/가 can change the nuance of a sentence. Using 은/는 often sounds more general or contrastive, while 이/가 can sound more direct or focused. When speaking with staff, using polite request forms like 주세요 is essential. Koreans may also omit subjects when obvious, so you will hear sentences without 저는 or 제가. Listening for context is key.
One thing to watch for
Using 은/는 and 이/가 interchangeably without considering context, such as saying 저는 사과를 먹어요 when answering 'Who eats an apple?'
Try this instead: If the question is 'Who eats an apple?', the natural answer is 제가 사과를 먹어요, using 이/가 to focus on 'I' as the new information. Using 저는 there can sound like you are starting a new topic rather than answering the question.
Your turn
Try answering out loud before checking a possible answer.
1How would you say 'I drink water' using the topic marker?
Show a sample answer
저는 물을 마셔요.
저는 marks 'I' as the topic, 물을 is the object with the object marker 을, and 마셔요 is the verb. This is a neutral statement.
2If someone asks 'Who ate the apple?', how would you answer 'I ate it'?
Show a sample answer
제가 먹었어요.
제가 uses the subject marker 가 to emphasize that 'I' am the one who ate it. The object 사과를 can be omitted because it is understood.
3What is the difference between 은/는 and 이/가 in simple terms?
Show a sample answer
은/는 marks the topic (what the sentence is about), while 이/가 marks the subject (who or what does the action), often introducing new information or emphasis.
This is a simplified explanation. In many sentences, either can be used, but the nuance changes. 은/는 is often used for general statements or contrasts, and 이/가 for specific focus.
Remember: Korean sentences end with the verb, and the topic marker 은/는 tells what the sentence is about, while the subject marker 이/가 points to who or what does the action. Practice both to sound natural.
