Permission -아/어도 되다 in Korean

In Brief

Use verb stem + -아/어도 돼요? to ask politely whether an action is allowed: 여기 앉아도 돼요? means “May I sit here?” The same form as a statement gives permission: 앉아도 돼요 means “You may sit.” For prohibition, prefer -(으)면 안 돼요 (“must not”), because 안 + verb + -아/어도 돼요 normally means “do not have to.”

Overview

-아/어도 되다 is the standard Korean pattern for saying that an action is acceptable or permitted. You will hear it when someone asks to enter, borrow an object, take a photograph, leave early, or use a facility. It is introduced around A2 because it combines familiar polite endings with a connective ending, -아/어도, attached to a verb stem (the part left after removing 다).

English often uses a modal verb such as “may” or “can”: “May I come in?” or “Can I use this?” Korean builds the meaning differently. 들어가도 되다 is closer in structure to “it is okay even if [someone] enters.” In real conversation, however, translate the whole pattern naturally as “may,” “can,” “be allowed to,” or “it is okay to.” Do not try to preserve the words “even if” in every English translation.

This expression also belongs to a useful family of rules about choice and obligation. Compare permission 가도 돼요 (“you may go”), no obligation 안 가도 돼요 (“you do not have to go”), and prohibition 가면 안 돼요 (“you must not go”). Keeping these three patterns separate prevents one of the most consequential beginner misunderstandings.

How It Works

The basic pattern

Start with the dictionary form of an action verb, remove 다 to find its stem, add -아도 or -어도, and then add 되다.

Step	Korean	Meaning
Dictionary form	앉다	to sit
Verb stem	앉-	sit-
Add the connective ending	앉아도	even if [someone] sits
Add 되다 and a polite ending	앉아도 돼요	it is okay to sit / may sit

In everyday polite speech, 되어요 contracts to 돼요. The spelling 되요 is incorrect. Both 되어요 and 돼요 are grammatical, but 돼요 is overwhelmingly more natural in ordinary conversation.

Choosing -아도 or -어도

The choice follows the same vowel pattern used by many Korean endings.

Stem type	Ending	Dictionary form	Permission form
Last stem vowel is ㅏ or ㅗ	-아도	앉다	앉아도 돼요
Other last stem vowel	-어도	먹다	먹어도 돼요
하다 verb	해도	사용하다	사용해도 돼요
Vowels combine or contract	contracted form	가다 / 보다 / 쓰다	가도 / 봐도 / 써도 돼요

The subject is usually omitted when the situation makes it obvious. 들어가도 돼요? can therefore mean “May I go in?”, “May we go in?”, or even “May they go in?” Context supplies the person. When asking permission for your own action, listeners normally understand the omitted subject as “I” or “we.”

Asking permission

A rising intonation and a question mark turn the polite statement into a permission question:

• 창문을 열어도 돼요? — May I open the window?
• 지금 전화해도 돼요? — Is it okay if I call now?

The ending -아/어도 될까요? is softer and more tentative. Literally, it asks whether it would be acceptable. It is useful with a stranger, a teacher, a customer, or anyone whose decision you do not want to presume.

• 먼저 가도 될까요? — Would it be all right if I left first?
• 여기에서 사진을 찍어도 될까요? — Would it be all right to take a photo here?

Other speech levels are possible:

Form	Typical effect	Example
-아/어도 돼?	casual, to a close friend or younger person	이거 먹어도 돼?
-아/어도 돼요?	polite everyday question	이거 먹어도 돼요?
-아/어도 될까요?	polite and tentative	이거 먹어도 될까요?
-아/어도 됩니까?	formal and direct	들어가도 됩니까?

Giving permission

You can repeat the requested action, use a short answer, or invite the person to act.

• 네, 앉아도 돼요. — Yes, you may sit.
• 네, 돼요. — Yes, you may / Yes, that is allowed.
• 네, 괜찮아요. — Yes, that is fine.
• 네, 앉으세요. — Yes, please sit.
• 그렇게 해도 돼요. — You may do it that way / That is fine.

A bare 네 often works when the question is clear, but repeating the verb avoids ambiguity. 하세요 is not the permission construction itself; it is an honorific invitation or instruction (“please do it”), and is often a natural positive response.

Refusing permission

For a clear prohibition, use verb stem + -(으)면 안 되다, literally “if [someone] does it, it is not okay.” Add -으면 after most consonant-final stems and -면 after vowel-final stems or a stem ending in ㄹ.

Allowed	Not allowed
여기 앉아도 돼요. — You may sit here.	여기 앉으면 안 돼요. — You must not sit here.
사진을 찍어도 돼요. — You may take photos.	사진을 찍으면 안 돼요. — You must not take photos.
들어가도 돼요. — You may enter.	들어가면 안 돼요. — You must not enter.

In conversation, 안 돼요 alone can mean “No, you may not” or “That is not allowed.” Because it can sound firm, a reason or apology often softens a refusal: 죄송하지만, 지금은 들어가면 안 돼요 (“I’m sorry, but you cannot enter now”).

Permission, no obligation, and prohibition

Word order changes the meaning:

Pattern	Core meaning	Example
V-아/어도 되다	permission	가도 돼요. — You may go.
안 V-아/어도 되다	no obligation	안 가도 돼요. — You do not have to go.
V-지 않아도 되다	no obligation, longer negative	가지 않아도 돼요. — You do not have to go.
V-(으)면 안 되다	prohibition	가면 안 돼요. — You must not go.

English “don’t have to” and “must not” are also different, but casual English sometimes blurs permission and ability with “can.” Korean makes the intended rule explicit through the ending, so learn each complete pattern rather than translating 안 by itself as “not.”

Common Mistakes

Writing 되요 instead of 돼요

• Wrong: 여기 앉아도 되요?
• Right: 여기 앉아도 돼요?
• Why: 돼요 is the contraction of 되어요. If you can expand the form to 되어요, spell the contraction 돼요.

Using prohibition when you mean lack of obligation

• Wrong for “You don’t have to come”: 오면 안 돼요.
• Right: 안 와도 돼요. / 오지 않아도 돼요.
• Why: 오면 안 돼요 means “You must not come.” Put the negative inside the permitted action to say that not coming is also acceptable.

Negating 되다 to build every refusal

• Awkward as a beginner default: 사진을 찍어도 안 돼요.
• Natural clear rule: 사진을 찍으면 안 돼요.
• Why: Korean can use -아/어도 안 되다 for emphatic meanings such as “not allowed even if…,” but -(으)면 안 되다 is the dependable basic pattern for “must not.”

Attaching the ending to the dictionary form

• Wrong: 먹다어도 돼요?
• Right: 먹어도 돼요?
• Why: Remove 다 first, then attach -아도/-어도 to the stem: 먹다 → 먹- → 먹어도.

Treating permission as physical ability

• Misleading: 수영해도 돼요? for “Can you swim?”
• Right for ability: 수영할 수 있어요?
• Why: 수영해도 돼요? asks whether swimming is allowed. -(으)ㄹ 수 있다 asks whether someone has the ability or opportunity to swim. English “can” covers both meanings; Korean normally distinguishes them.

Using a casual ending in a formal relationship

• Too casual to a professor: 먼저 가도 돼?
• Better: 먼저 가도 될까요?
• Why: 돼? suits close relationships. The tentative 될까요? shows more consideration when asking someone in authority.

Usage Notes

Choose politeness for the situation

-아/어도 돼요? is already polite and fits most routine interactions. -아/어도 될까요? does not change the basic permission meaning; it makes the request less presumptive. In a highly formal announcement or institutional setting, -아/어도 됩니까? may appear, but it can sound official rather than warm.

Korean politeness involves more than swapping sentence endings. When a request inconveniences someone, speakers often add 혹시 (“perhaps/by any chance”), 죄송하지만 (“I’m sorry, but”), or a reason:

• 혹시 창문을 열어도 될까요? — Would it perhaps be all right to open the window?
• 죄송하지만, 먼저 가도 될까요? — I’m sorry, but may I leave first?

Particles may disappear in speech

The concept example 사진 찍어도 돼요? omits the object particle 을 from 사진을. This is common when the relationship between the words is obvious. 사진을 찍어도 돼요? is equally correct and slightly more explicit. Do not assume that every omitted particle is ungrammatical simply because careful written Korean includes it.

Natural positive and negative answers

A yes/no answer can be confusing when the question contains a negative idea, so repeating the action is safest. To 안 가도 돼요? (“Do I not have to go?”), say 네, 안 가도 돼요 (“Right, you do not have to go”) or 아니요, 가야 해요 (“No, you have to go”). The full response makes the rule unmistakable.

Beyond the Basics / Advanced Use

You do not need to master all of these points at A2, but they explain forms you will meet later.

-아/어도 괜찮다 and -아/어도 좋다

괜찮다 (“to be okay”) often replaces 되다, especially when asking whether something will bother another person: 여기 앉아도 괜찮아요? (“Is it okay if I sit here?”). -아/어도 좋다 can also grant permission, but may sound more like “it is fine/good to do” and appears frequently in instructions or writing. 되다 remains the safest general-purpose choice for permission.

Permission concerning a completed action

The past form can ask whether something already done was acceptable:

• 제가 그렇게 말했어도 괜찮았어요? — Was it okay that I said that?

Such sentences depend heavily on context and can overlap with hypothetical or concessive meanings. Beginners should normally ask permission before acting with the present-looking form 말해도 돼요?, even when the intended action is in the near future.

-아/어도 되겠습니까 and deferential requests

-아/어도 되겠습니까? adds -겠-, which can make a formal request more cautious: 질문 하나 해도 되겠습니까? (“May I ask one question?”). In ordinary polite conversation, 질문 하나 해도 될까요? is usually less stiff.

The wider meaning of -아/어도

Without 되다, -아/어도 commonly means “even if” or “although”: 비가 와도 가요 (“I go even if it rains”). Permission developed from the idea that the result is acceptable even if an action happens. Recognizing this connection helps, but do not translate permission questions word for word; 가도 돼요? is naturally “May I go?”

The pattern can also attach to descriptive verbs (words that function like adjectives in English): 조금 늦어도 돼요? means “Is it okay if I am a little late?” With nouns plus 이다, you may encounter forms such as 학생이어도 돼요? (“Is it okay if the person is a student?”). These extensions retain the central idea that a condition is acceptable, though they do not always concern permission in the narrow sense.

Practice Tips

1. Build three-way sets. Take one familiar verb and say permission, no obligation, and prohibition: 먹어도 돼요, 안 먹어도 돼요, 먹으면 안 돼요. Repeat with 가다, 사용하다, and 찍다 until the meanings no longer blur together.
2. Practice realistic mini-dialogues. Choose objects and places around you: 이거 써도 돼요? — 네, 써도 돼요. Then give a refusal with a reason: 아니요, 지금은 쓰면 안 돼요.
3. Listen for the ending, not just 되다. When watching Korean media, note whether you hear -아/어도, 안 -아/어도, or -(으)면 안. The material before 되다 tells you whether the speaker means permission, no obligation, or prohibition.
