한국어를 배울 수 있어요Ability, Requests, and Learning

Talking about what you can and cannot do with -(으)ㄹ 수 있어요 and 못, describing how well you do something with 잘/조금, and asking someone for a favor with 아/어 주세요 · Speak and Write Korean: Foundations of Practical Communication

Chapter Objectives

By the end of this chapter, you will be able to:

  1. Say what you can and cannot do using -(으)ㄹ 수 있어요 and -(으)ㄹ 수 없어요.
  2. Use 못 to say that you are unable to do something.
  3. Describe how well you do something using 잘 and 조금.
  4. Ask someone to do something for you using 아/어 주세요.
  5. Talk about learning a language, skill, or hobby in everyday polite speech.
  6. Read and write short exchanges about ability and requests.
  7. Maintain accurate Hangeul, spacing, particles, and everyday polite speech level while combining this chapter's ability and request language with vocabulary and grammar from Chapters 1–12.

Communication Scenario

라일라 has been taking Korean classes at the language school for a few weeks now. Her classmate 수진 asks her about her hobbies and what she can do in Korean so far. 라일라 wants to say that she can order food and ask for directions in Korean, but she still cannot write long messages. She also wants to ask 수진 to speak a little more slowly. To do this, she needs a way to talk about ability, skill level, and polite requests — something Chapter 12's direction and route language cannot yet do on its own.

  1. This chapter introduces ability with -(으)ㄹ 수 있어요, inability with 못, skill level with 잘/조금, and requests with 아/어 주세요.
  2. Every task below builds on identity, family, dates, food, routines, location, shopping, plans, and directions language already active from Chapters 1–12.
  3. By the end of this chapter you will be able to describe what you can and cannot do and ask someone politely for help.

Productive load: approximately 30 items, counting this chapter's vocabulary together with ability and request patterns practiced below.

발음 — Pronunciation Focus

Pronunciation Focus

This chapter's main pronunciation target is the batchim linking that occurs when the ending -을 수 있어요 follows a consonant-final stem, and the pronunciation of 못 before a following verb.

Pronunciation Note — Linking before -을 수 있어요 and 못 before verbs

When a consonant-final stem is followed by -을 수 있어요, the batchim links forward into the following syllable, so 읽을 수 있어요 is pronounced closer to [il-geul su i-sseo-yo]. Separately, 못 before a vowel-initial verb such as 못 와요 also links forward, closer to [mo dwa-yo]. This is the same liaison pattern practiced with particles and endings since Chapter 8, now applied to this chapter's ability and negation forms.

Read the following aloud, listening for the linked sound between each syllable.

할 수 있어요 · 읽을 수 있어요 · 못 가요 · 못 와요

받침 점검: continue distinguishing 을 수 있어요 after consonant-final stems from ㄹ 수 있어요 after vowel-final or ㄹ-final stems, as introduced in this chapter's grammar section.

Grammar and Sentence Patterns

문법 1 — Ability: -(으)ㄹ 수 있어요/없어요

Communicative purpose: say what you are able or unable to do.

-(으)ㄹ 수 있어요 attaches to a predicate stem to express ability, and -(으)ㄹ 수 없어요 expresses inability. Use -ㄹ 수 있어요 after a vowel-final stem and -을 수 있어요 after a consonant-final stem.

Dictionary formStem type-(으)ㄹ 수 있어요 form
가다vowel-final갈 수 있어요
운전하다vowel-final운전할 수 있어요
읽다consonant-final읽을 수 있어요
만들다ㄹ-final만들 수 있어요
  • 저는 한국 음식을 만들 수 있어요. I can make Korean food. 만들다 → 만들 수 있어요
  • 저는 아직 한국어를 잘 읽을 수 없어요. I still cannot read Korean well. 읽다 → 읽을 수 없어요

문법 2 — Inability: 못

Communicative purpose: say that you are unable to do something, often for a reason outside your control.

못 is placed directly before an action verb to express inability. It functions similarly to short negation 안, introduced in Chapter 6, but specifically marks inability rather than simple negation or unwillingness.

  • 오늘 저는 학교에 못 가요. I can't go to school today.
  • 저는 수영을 못 해요. I can't swim.
Grammar Note — 못 versus 안

Since Chapter 6, 안 has marked simple negation, as in 안 가요 ("I'm not going," by choice). 못 specifically marks inability, as in 못 가요 ("I can't go," due to a reason beyond the speaker's control). The two are not interchangeable: choosing between them changes whether the sentence describes a choice or a limitation.

문법 3 — Degree adverbs: 잘/조금

Communicative purpose: describe how well you do something.

잘 ("well") and 조금 ("a little") are placed before the verb to describe skill level. They frequently appear together with -(으)ㄹ 수 있어요 or with the plain present tense.

  • 저는 한국어를 조금 할 수 있어요. I can speak a little Korean.
  • 제 친구는 한국어를 잘해요. My friend speaks Korean well.

These degree adverbs pair naturally with the learning vocabulary introduced in this chapter, such as 배우다 and 외국어.

문법 4 — Requests: 아/어 주세요

Communicative purpose: politely ask someone to do something for you.

아/어 주세요 attaches to a predicate stem to ask someone to do an action for your benefit. It builds on the everyday polite -아요/어요 pattern practiced since Chapter 6: choose 아 주세요 or 어 주세요 the same way you would choose between -아요 and -어요.

Dictionary formVowel pattern아/어 주세요 form
기다리다ㅣ stem기다려 주세요
설명하다하다 verb설명해 주세요
도와주다ㅘ stem도와주세요
  • 조금 천천히 말해 주세요. Please speak a little more slowly.
  • 다시 한번 설명해 주세요. Please explain that one more time.
  • 저를 도와주세요. Please help me.
Grammar Note — -(으)세요 versus 아/어 주세요

Chapter 12 introduced -(으)세요 for polite instructions and directions, such as 오른쪽으로 가세요. 아/어 주세요 specifically asks someone to do something as a favor for the speaker's benefit, such as 도와주세요. ("Please help me.") Both remain within the everyday polite register, but they are used for different communicative purposes: instruction versus favor.

Language Building Block — Describing ability and making a request
저는 [활동]을/를 잘/조금 할 수 있어요/없어요. [상대방]이/가 [행동]아/어 주세요.
An ability statement with a degree adverb, followed by a polite request for help
저는 한국어를 조금 할 수 있어요. 천천히 말해 주세요.
I can speak a little Korean. Please speak slowly.

Practice — Building ability and request sentences

  1. Change 만들다 and 읽다 into their -(으)ㄹ 수 있어요 forms.
  2. Write one sentence using 못 to say you cannot do something today.
  3. Add 잘 or 조금 to describe your own skill level in a hobby or language.
  4. Change 기다리다 and 설명하다 into their 아/어 주세요 forms.

Model Dialogue

Setting: 수진 asks 라일라 about her hobbies and her Korean skills so far.

수진 라일라 씨, 취미가 뭐예요? Layla, what's your hobby?
라일라 저는 요리를 좋아해요. 한국 음식을 조금 만들 수 있어요. I like cooking. I can make a little Korean food.
수진 와, 잘해요? 한국어는 어때요? Wow, are you good at it? How about Korean?
라일라 한국어는 조금 할 수 있어요. 그런데 아직 잘 읽을 수 없어요. I can speak a little Korean. But I still can't read well.
수진 괜찮아요. 저도 처음에는 못 읽었어요. That's okay. I couldn't read at first either.
라일라 수진 씨, 조금 천천히 말해 주세요. 그리고 다시 한번 설명해 주세요. Sujin, please speak a little slowly. And please explain that one more time.
수진 네, 알겠어요. 제가 도와줄게요. Okay, got it. I'll help you.

내용 이해 — Comprehension questions:

  1. What is 라일라's hobby, and what can she make?
  2. What can 라일라 do in Korean, and what can she not yet do well?
  3. What two requests does 라일라 make of 수진?
  4. Find one sentence using -(으)ㄹ 수 있어요 and one sentence using 아/어 주세요 in the dialogue.

Reading

Below is a short message that 지훈 wrote to ask a classmate for help with a group project. Read it and answer the questions below.

지훈의 메시지

안녕하세요! 부탁이 있어요. 저는 컴퓨터를 잘 못해요. 발표 자료를 좀 도와주세요. 저는 한국어 설명은 쓸 수 있어요. 그런데 사진은 못 넣어요. 내일까지 도와줄 수 있어요? 고마워요!

This message recycles request language from Chapter 9's 주세요 and this chapter's ability, inability, and 아/어 주세요 patterns.

내용 이해 — Comprehension questions:

  1. What does 지훈 ask his classmate to help with?
  2. What can 지훈 already do by himself?
  3. What can 지훈 not do?
  4. Identify one sentence in the message that uses -(으)ㄹ 수 있어요.

Writing Workshop

This chapter's writing task is a short self-introduction of abilities, 제 실력 ("My Skills"), combining ability sentences with -(으)ㄹ 수 있어요/없어요, an inability sentence with 못, a skill-level sentence with 잘/조금, and at least one request with 아/어 주세요.

  1. Greet your reader. Use a greeting from Chapter 1.
  2. Name one thing you can do. Use -(으)ㄹ 수 있어요.
  3. Name one thing you cannot do. Use -(으)ㄹ 수 없어요 or 못.
  4. Describe your skill level. Use 잘 or 조금 in at least one sentence.
  5. Make one polite request. Use 아/어 주세요 to ask for help or patience.
  6. Revise. Check your draft against the editing checklist below.

체크리스트 — Editing checklist:

  • Every sentence uses only Hangeul and only systems activated through Chapter 13.
  • Speech level is consistent everyday polite -아요/어요, -(으)ㄹ 수 있어요, and 아/어 주세요 throughout.
  • -(으)ㄹ 수 있어요/없어요 is chosen correctly based on the final sound of the stem.
  • 못 is placed directly before the action verb it negates.
  • 잘 and 조금 are placed before the verb they describe.
  • 아/어 주세요 is formed correctly based on the stem's vowel pattern.
  • Spacing between nouns, particles, and predicates follows the patterns modeled in Chapters 1–12.

Speaking Practice

통제 연습 — Controlled practice: Can you...?

Working with a partner or alone, take turns asking and answering ...을/를 할 수 있어요? about at least four different activities, using 네, 할 수 있어요 or 아니요, 못 해요.

의사소통 과제 — Communicative task: 부탁하기

Work with a partner. One person describes something they cannot do well, then makes a polite request for help using 아/어 주세요. The other person responds appropriately.

혼자 하는 연습 — Solo alternative

Record yourself describing three things you can do, one thing you cannot do, and one polite request you would make of a Korean-speaking friend, in five to six connected sentences.

Culture and Communication

Culture in Context — Modesty about ability

When asked about a skill, it is common in many everyday South Korean conversations to downplay one's own ability rather than to state it confidently, even when the person is quite skilled; a modest answer such as 조금 할 수 있어요 is a common and polite response even from someone who is fairly proficient.

Culture in Context — Asking for help

Using 아/어 주세요 to ask for a favor, rather than a blunt command, is standard in everyday polite interaction, and adding a short expression of thanks such as 고마워요 after a request is common courtesy in both spoken and written Korean.

Common Mistakes to Avoid

Common Mistake — Wrong stem-final choice for -(으)ㄹ 수 있어요

Error: 읽다 → 읽ㄹ 수 있어요

Correction: 읽을 수 있어요 — a consonant-final stem takes 을 수 있어요, not ㄹ 수 있어요 alone.

Common Mistake — Confusing 안 and 못

Error: 저는 수영을 안 해요. (when the intended meaning is inability, not choice)

Correction: 저는 수영을 못 해요. — 못 marks inability, while 안 marks simple negation or unwillingness; the two express different meanings.

Common Mistake — Misplacing 잘 or 조금

Error: 저는 한국어 잘 할 수 있어요.

Correction: 저는 한국어를 잘할 수 있어요. — the object particle 를 should still appear after 한국어, and 잘 is placed immediately before the verb it modifies.

Common Mistake — Wrong vowel pattern for 아/어 주세요

Error: 기다리아 주세요

Correction: 기다려 주세요 — 기다리다 has a ㅣ-final stem, which combines with 어 to form 려, following the same contraction pattern practiced with -아요/어요 since Chapter 6.

누적 복습 — Cumulative review

This chapter recycles identity, family, dates, food, routines, location, shopping, plans, and directions language from Chapters 1 through 12, and adds ability with -(으)ㄹ 수 있어요, inability with 못, degree adverbs 잘/조금, and requests with 아/어 주세요. If any earlier item felt uncertain while completing this chapter, return to its source chapter before continuing to Chapter 14.

Practical Performance Task
