SECTION 1
Historical Context & Motivation
Asking questions about past events is one of the most fundamental acts of human communication. In Korean culture, storytelling and recounting shared experiences play a central role in building relationships, from casual conversations among friends to formal retellings at family gatherings. The Korean language has evolved a rich system of interrogative words (question words) and past tense markers that allow speakers to probe narratives with precision — pinpointing what happened, where it took place, when it occurred, and who was involved.

Today, the ability to ask and answer questions about past narratives in Korean is essential whether you are chatting with a friend about last weekend, discussing a K-drama episode, or recounting a travel story. The core challenge this lesson addresses is: How do you form accurate past-tense questions in Korean, and how do you respond to them naturally?
SECTION 2
Core Principles & Key Vocabulary
Before diving into full sentences, you need to internalize the building blocks. Korean questions about past narratives rely on four pillars: the correct question word (의문사, uimunsa), the appropriate past tense conjugation, the right sentence-ending particle to mark the sentence as a question, and proper subject and object particles to clarify who did what. Understanding each pillar gives you the flexibility to ask about any past event.

Question Endings (-어요?/-았어요?)
Particles (은/는, 이/가, 을/를, 에서, 에)

Visual Explanation — Question Sentence Structure
As the diagram illustrates, Korean sentence order follows a Subject–Object–Verb (SOV) pattern. This is different from English, where the verb sits in the middle. When forming a past-tense question, you simply place the question word in the appropriate position and conjugate the verb into past tense with rising intonation. The flexibility of Korean word order means that time and place adverbs can shift around, but the verb with its past tense ending always anchors the sentence at the end.
SECTION 4
How Past Tense Conjugation Works
The Past Tense Conjugation Formula
Korean past tense conjugation follows a predictable pattern. You start with the verb stem (the dictionary form minus -다), determine the last vowel of the stem, and then attach the correct past tense suffix. Finally, you add the speech level ending. For polite informal speech (the most common in everyday conversation), the process looks like this.
PAST TENSE POLITE INFORMAL
Use -았어요 when the last vowel of the stem is ㅏ or ㅗ (bright vowels). Use -었어요 for all other vowels (dark vowels). Use -였어요 (or -했어요) specifically for 하다 verbs.
| Verb (Dictionary) | Stem | Last Vowel | Past Polite | Meaning |
|---|---|---|---|---|
| 가다 (gada) | 가 | ㅏ (bright) | 갔어요 | went |
| 먹다 (meokda) | 먹 | ㅓ (dark) | 먹었어요 | ate |
| 보다 (boda) | 보 | ㅗ (bright) | 봤어요 | saw / watched |
| 만나다 (mannada) | 만나 | ㅏ (bright) | 만났어요 | met |
| 하다 (hada) | 하 | 하 (하다 verb) | 했어요 | did |
| 오다 (oda) | 오 | ㅗ (bright) | 왔어요 | came |

Detailed Breakdown of Question Types
When discussing a past narrative, your questions will generally fall into four categories: what happened, where it happened, when it happened, and who was involved. Each type uses a specific question word and pairs with appropriate particles. Let's examine each type with its question-and-answer pattern.

SECTION 6
Worked Example — Discussing a Short Narrative
Let's work through a complete conversational scenario. Imagine your Korean friend 지수 (Jisu) tells you a short story, and you want to ask follow-up questions to understand the full picture. Here is the narrative and the step-by-step process for forming and answering questions.
The Narrative (이야기)
Asking & Answering Questions About Jisu's Story
- 1
Step 1 — Ask WHAT happened (뭐)
To ask what Jisu did, replace the specific activity with 뭐 and keep the verb in past tense. You ask: "주말에 뭐 했어요?" (What did you do on the weekend?). The verb 하다 (to do) becomes 했어요 in past tense because 하 is a 하다 verb, taking the -였/-했 suffix.Answer: 맛있는 떡볶이를 먹었어요. (I ate delicious tteokbokki.) - 2
Step 2 — Ask WHERE it happened (어디)
To ask where she ate, use 어디 with the location particle 에서 (indicating where an action takes place). You ask: "어디에서 먹었어요?" (Where did you eat?). The verb 먹다 (to eat) becomes 먹었어요 because the stem 먹 ends in a dark vowel (ㅓ).Answer: 홍대에서 먹었어요. (I ate in Hongdae.) - 3
Step 3 — Ask WHEN it happened (언제)
To ask when, simply place 언제 at the beginning or where the time expression would go. You ask: "언제 갔어요?" (When did you go?). Here 가다 (to go) becomes 갔어요 because 가 ends in ㅏ (bright vowel), and the stem contracts with -았.Answer: 지난 주말에 갔어요. (I went last weekend.) - 4
Step 4 — Ask WITH WHOM (누구하고)
To ask who accompanied Jisu, use 누구 with the companion particle 하고 (or 랑 in casual speech). You ask: "누구하고 갔어요?" (With whom did you go?). Notice we use 누구하고, not 누가하고 — because 누구 is not the subject here, it's the companion.Answer: 수진이하고 갔어요. (I went with Sujin.) - 5
Step 5 — Combine into a Full Follow-Up Exchange
In natural conversation, you often combine elements. A natural follow-up might be: "어떤 떡볶이를 먹었어요? 맛있었어요?" (What kind of tteokbokki did you eat? Was it good?). Here, 어떤 (what kind of) adds a new dimension, and 맛있다 (to be delicious) conjugates to 맛있었어요 in past tense to ask about the experience.Answer: 치즈 떡볶이를 먹었어요. 네, 정말 맛있었어요! (I ate cheese tteokbokki. Yes, it was really delicious!)
SECTION 7
Formality Levels — Asking Questions at Different Speech Levels
Korean has multiple speech levels (존댓말 and 반말), and the formality of your question changes depending on whom you're speaking with. The same question — 'What did you do yesterday?' — sounds very different when you ask a teacher versus a close friend. This section compares the three most commonly encountered levels so you can adapt your questions to any social context.
| Speech Level | Ending Pattern | Example Question | When to Use |
|---|---|---|---|
| Formal Polite (합쇼체) | -았/었습니까? | 어제 뭐 하셨습니까? (What did you do yesterday?) | Business meetings, presentations, speaking with elders you don't know well |
| Polite Informal (해요체) | -았/었어요? | 어제 뭐 했어요? (What did you do yesterday?) | Most everyday conversations, classmates, acquaintances, service encounters |
| Casual (반말/해체) | -았/었어? | 어제 뭐 했어? (What'd you do yesterday?) | Close friends of similar age, younger siblings, very informal settings |

Connecting to Advanced Narrative Skills
Once you are comfortable asking basic 뭐/어디/언제/누구 questions in the past tense, you can expand into more sophisticated narrative questioning. Advanced Korean conversation involves asking about reasons, methods, feelings, and sequences of events. The table below shows how your current skills connect to these next-level patterns.
| Current Skill | Advanced Extension |
|---|---|
| 뭐 했어요? (What did you do?) | 왜 그렇게 했어요? (Why did you do that?) — adds reason-asking with 왜 (why) |
| 어디에서 먹었어요? (Where did you eat?) | 어떻게 거기에 갔어요? (How did you get there?) — adds method-asking with 어떻게 (how) |
| 언제 갔어요? (When did you go?) | 가기 전에 뭐 했어요? (What did you do before going?) — adds sequencing with -기 전에 (before doing) |
| 누구하고 갔어요? (With whom?) | 그 사람은 어떤 사람이에요? (What kind of person is that?) — adds description with 어떤 (what kind of) |
| Basic past -았/었어요 | Past experience -아/어 본 적이 있어요? (Have you ever...?) — adds experiential past |
How basic narrative questions scaffold into advanced conversational skills
The key insight is that every advanced question pattern builds directly on the foundation you are learning now. Once 뭐 했어요? becomes second nature, adding 왜 (why) or 어떻게 (how) is simply a matter of swapping one question word for another and adjusting the verb as needed. Similarly, learning to chain past events with connectors like -고 (and then), -아서/어서 (because), and -기 전에 (before doing) allows you to discuss entire story arcs rather than isolated events.

SUMMARY
Lesson Summary
Summary
In this lesson, you learned how to ask and answer questions about past narratives in Korean using four essential question words (의문사): 뭐 (what), 어디 (where), 언제 (when), and 누구 (who/whom). You practiced the past tense conjugation system (-았/었/였어요) based on vowel harmony — bright vowels take -았, dark vowels take -었, and 하다 verbs take -했. You learned that Korean questions in the polite informal (해요체) level are formed by simply raising your intonation at the end of a past tense statement.
You explored the SOV (Subject–Object–Verb) sentence structure that governs all Korean sentences, saw how particles (에서, 하고, 이/가, 을/를) mark grammatical roles, and practiced through a worked example conversation about eating tteokbokki in Hongdae. You also compared three speech levels — formal polite (합쇼체), polite informal (해요체), and casual (반말) — to ensure you can adjust your questions to any social situation. With these tools, you are ready to engage in real Korean conversations about stories, events, and shared experiences.
