-(으)ㄹ까요 vs -(으)ㄹ래요: What Is the Difference?

What you'll learn

• Decide between a proposal (-(으)ㄹ까요) and a question about a wish (-(으)ㄹ래요) in one sentence.
• Say "Shall I...?" and "I wonder if..." with -(으)ㄹ까요, which -(으)ㄹ래요 cannot do.
• Answer each question in the form a Korean speaker expects.
• Avoid the usual mistake of using -(으)ㄹ까요 to say what you want.

Before you start: you should know the polite ending -아요/-어요 and common verbs such as 가다, 먹다 and 열다. The full rules for each pattern live in the lessons on -(으)ㄹ까요? and -(으)ㄹ래요. It plays only when you press a button.

What Is the Difference between -(으)ㄹ까요 and -(으)ㄹ래요?

The difference is who decides. -(으)ㄹ까요 puts the decision on the table for both people: "Shall we do this? Shall I do that?" -(으)ㄹ래요 asks about, or states, one person's own wish: "Do you want to? I want to."

One pair shows the contrast:

• 같이 먹을까요? (gachi meogeulkkayo?) [가치 머글까요] = "Shall we eat together?" The speaker proposes an activity and invites the listener to agree.
• 저는 이걸 먹을래요. (jeoneun igeol meogeullaeyo.) [머글래요] = "I will have this one." The speaker states a personal choice, as when ordering.

Both sentences contain the verb 먹다 and both are polite. The first is a question that expects 네, 좋아요. The second is a statement of choice that expects nothing. The next sections turn this into a rule you can apply in a few seconds.

The One-Line Rule

Use -(으)ㄹ까요 to propose, to offer or to wonder, and use -(으)ㄹ래요 to ask or say what someone wants. If the English is "shall", choose -(으)ㄹ까요. If the English is "want to", choose -(으)ㄹ래요.

-(으)ㄹ까요 vs -(으)ㄹ래요: Side-by-Side Table

The table compares the two endings on the points learners need most. Each row has one specific answer for each ending.

The table shows that -(으)ㄹ까요 covers more ground: it can be used for offers, for third persons, for adjectives and for the past. -(으)ㄹ래요 covers a narrower field but speaks more directly. Each ending has typical situations.

When Do You Use -(으)ㄹ까요?

Use -(으)ㄹ까요 in three situations. In each, the speaker does not claim to know what should happen.

1. A proposal for "we". You suggest an activity: 같이 먹을까요? (gachi meogeulkkayo?) = "Shall we eat together?" The listener answers 네, 좋아요.
2. An offer for "I". You ask whether to do something for the listener: 창문 열까요? (changmun yeolkkayo?) = "Shall I open the window?"
3. Wondering about something. You think aloud, or ask what the listener thinks: 내일 비가 올까요? (naeil biga olkkayo?) = "Do you think it will rain tomorrow?" or "I wonder if it will rain tomorrow."

Question words work too: 뭐 먹을까요? (mwo meogeulkkayo?) = "What shall we eat?" This is a wh-question, so the stress sits on 뭐 and the sentence often ends with a fall or a rise-fall, not a sharp rise. A sharp final rise would make 뭐 sound like "something".

To build the ending, take the stem and add the right form of -(으)ㄹ. A stem that ends in a vowel adds ㄹ to the last block (가 + ㄹ = 갈). A stem that ends in a consonant adds 을 (먹 + 을 = 먹을). A stem that already ends in ㄹ keeps it (열 stays 열). Then add 까요: 갈까요, 먹을까요, 열까요. The ㄲ is already tense in the spelling, so you hear [갈까요] and write kk in Revised Romanization (galkkayo).

When Do You Use -(으)ㄹ래요?

Use -(으)ㄹ래요 when the sentence is about someone's own wish. It has three main jobs:

1. Asking the listener's wish. 같이 갈래요? (gachi gallaeyo?) [가치 갈래요] = "Do you want to go together?" The listener must answer with a wish.
2. Stating your choice. 저는 이걸 먹을래요. (jeoneun igeol meogeullaeyo.) = "I will have this one." Orders in cafés and restaurants often use this pattern.
3. Refusing or deciding against. 오늘은 안 갈래요. (oneureun an gallaeyo.) = "I don't want to go today."

The second person is always the one whose wish is in play. 민수 씨는 뭐 먹을래요? (minsu ssineun mwo meogeullaeyo?) = "What do you want to eat, Minsu?" asks Minsu directly. If you talk about someone who is not in the conversation, -(으)ㄹ래요 does not work. Use -고 싶어 해요 (he wants to) instead.

Worked Example: Choosing a Meal Together

Follow the steps as two friends pick lunch. Notice where the group decides and where each person decides.

1. Start with a shared question. Friend A asks 뭐 먹을까요? (mwo meogeulkkayo?) = "What shall we eat?" The decision belongs to both people, so -(으)ㄹ까요 fits.
2. Ask one person's wish. Friend A then turns to Minsu: 민수 씨는 뭐 먹을래요? (minsu ssineun mwo meogeullaeyo?) = "What do you want to eat, Minsu?" Now only Minsu's wish matters, so -(으)ㄹ래요 fits.
3. State the choice. Minsu answers 저는 냉면 먹을래요. (jeoneun naengmyeon meogeullaeyo.) = "I will have cold noodles." He repeats the ending of the question and states his own wish.

You will know it worked when the first question uses "we" and the second uses "you". The usual slip at this stage is to ask the whole table 뭐 먹을래요?, which sounds like asking each person to shout a wish at once. A shared decision starts with 먹을까요.

Can You Use Both in the Same Situation?

Yes, in invitations the two endings overlap, but the feeling differs.

• Inviting. 같이 갈까요? means "Shall we go together?" and offers an easy way out. 같이 갈래요? means "Do you want to go together?" and asks for a yes or no. Both are natural. The first is gentler.
• Service. Shops and offices use -(으)ㄹ까요 for offers: 제가 도와드릴까요? (jega dowadeurilkkayo?) = "Shall I help you?" A shop assistant would not say 도와드릴래요, because an offer of service is not a question about wishes.
• Elders. 먼저 드실래요? is possible, but a respectful offer such as 먼저 드시겠어요? is safer when the listener is senior.

Some limits are firm. Only -(으)ㄹ까요 can wonder about the weather, a third person or the past. Only -(으)ㄹ래요 can state a wish. An honest limit: this page describes the textbook contrast. Real speech mixes the two in invitations, and tone of voice decides how strong the invitation feels. The next step turns the contrast into a short decision procedure.

Which Should You Pick? a Simple Rule of Thumb

Follow these steps in order. The first step that applies gives the answer.

1. Is the subject a third person, an adjective, or the past? Use -(으)ㄹ까요: 그 사람이 올까요?
2. Are you offering to do something for the listener? Use -(으)ㄹ까요: 제가 할까요?
3. Are you proposing something for both of you? Use -(으)ㄹ까요: 같이 할까요?
4. Are you asking what the listener wants? Use -(으)ㄹ래요: 뭐 할래요?
5. Are you stating your own choice? Use -(으)ㄹ래요: 저는 이걸 할래요.

Checkpoint: read your sentence aloud with "shall" in English. If it still makes sense, -(으)ㄹ까요 is right. If "do you want to" makes more sense, choose -(으)ㄹ래요.

What Mistakes Do Learners Make with These Two?

Learners most often mix up who is deciding. Five mistakes appear again and again, and each has a quick repair.

1. Using -(으)ㄹ까요 to state a wish. Learners often assume the ending is a polite "will". Actually, 저는 집에 갈까요 is not a statement; it asks "Shall I go home?" To say what you want, use 저는 집에 갈래요.
2. Using -(으)ㄹ래요 for a third person. 민수 씨는 갈래요 is not natural when Minsu is not in the conversation. Say 민수 씨는 가고 싶어 해요 (Minsu wants to go), or ask Minsu directly.
3. Answering a proposal with the verb alone. After 같이 먹을까요?, the usual answer is 네, 좋아요. Replying 네, 먹을까요 repeats the question and confuses the listener.
4. Using -(으)ㄹ래요 with a past marker. 갔을래요 is not used. For the past, use -(으)ㄹ까요 in the form 갔을까요? ("I wonder if he went").
5. Missing the intonation. A yes/no question such as 같이 갈래요? usually rises. A wh-question such as 뭐 먹을까요? often ends with a fall or a rise-fall. A sharp rise on a wh-question changes the meaning to "something".

An honest limit: -(으)ㄹ래요 can sound strong-willed when you use it with someone senior. The pattern is not rude, but a softer wording such as -고 싶어요 ("I would like to") is safer in a formal setting.

Practice: Choose the Right Pattern

Try the five items before you read the answer key. Cover the answers with your hand.

1. Choose. You see that the room is stuffy and want to offer to open the window. Complete: 창문 ___? (열까요 / 열래요)
2. Choose. You wonder whether the weather will be rainy tomorrow. Complete: 내일 비가 ___? (올까요 / 올래요)
3. Ask. Ask a friend what they want to drink. Use 마시다 and the ending that asks for a wish.
4. Choose. At a restaurant, you decide on bibimbap. Complete: 저는 비빔밥 ___. (먹을까요 / 먹을래요)
5. Fix the error. A learner wants to say "I will rest on the weekend" and writes 저는 주말에 쉴까요. Correct it.

Answer key

1. 열까요. It is an offer, and "shall I" calls for -(으)ㄹ까요.
2. 올까요. The speaker wonders about the weather, and only -(으)ㄹ까요 can do that.
3. 뭐 마실래요? (mwo masillaeyo?) You ask about the listener's wish, so -(으)ㄹ래요 fits. Let the wh-question end with a fall or rise-fall.
4. 먹을래요. You state your own choice.
5. 저는 주말에 쉴래요. The original is a question ("Shall I rest?"), not a statement.

If you got four or five right, you can already handle most daily uses. If you missed items 1 and 2, review the three uses of -(으)ㄹ까요 above.

What Should You Learn Next?

After -(으)ㄹ까요 vs -(으)ㄹ래요, study each pattern on its own, then the neighbouring contrasts. This page compares the two endings but does not teach every use of either one.

1. Read the full lessons: -(으)ㄹ까요? and -(으)ㄹ래요.
2. Add the third suggestion form in -(으)ㅂ시다 vs -(으)ㄹ까요 vs -자.
3. Compare the wish ending with the promise ending in -(으)ㄹ게요 vs -(으)ㄹ래요.
4. See every pair on Confusing Grammar Compared, or browse Beginner Grammar for the patterns around level A2.

With these steps, the choice in -(으)ㄹ까요 vs -(으)ㄹ래요 becomes automatic: decide whether you are proposing or asking for a wish, then add the ending to the verb stem.

Frequently Asked Questions

Can I always replace -(으)ㄹ까요 with -(으)ㄹ래요?

No. -(으)ㄹ래요 cannot offer help ("Shall I open the window?"), cannot wonder ("Will it rain?") and cannot be used for a third person or an adjective. Replace only when you invite someone and want to ask for their wish directly: 같이 갈까요? and 같이 갈래요? both invite.

Which one sounds more natural in speech?

Both are everyday forms. -(으)ㄹ까요 is the first choice when you suggest something together or ask "shall I", because it leaves the listener room to say no. -(으)ㄹ래요 is natural among friends, family and in shops when you ask for a decision. Neither is formal.

How do I answer -(으)ㄹ까요? politely?

Agree with 네, 좋아요 or 그래요, and decline with 글쎄요, 저는 괜찮아요 or 다음에 해요. You do not repeat the verb, because the question was a suggestion rather than a request for your wish. A -(으)ㄹ래요 question, by contrast, is answered with the verb: 네, 갈래요.

Can -(으)ㄹ까요 be used when I talk to myself?

Yes. Speakers often use it as a thinking-aloud question: 뭐 먹을까? (What shall I eat?) or 어디 갈까? Without a listener, it works as "I wonder what to do". This is the same -(으)ㄹ까 form, with 요 added only when a listener is present.

What is the quickest rule to remember?

Ask who decides. If the choice is shared or you are offering, use -(으)ㄹ까요: "Shall we? Shall I?" If the listener alone decides what they want, or you state your own choice, use -(으)ㄹ래요: "Do you want to? I want to."
