Teach ‘-(으)면 안 돼요?’ as a rule-check (not a scold) using a 3-way intent tree and 10 rewrites that remove accusatory tone.
The one rule you need
-(으)면 안 돼요?-(eu)myeon an dwaeyo? is a polite question that checks whether an action is allowed.
The same words without a question mark often land as a prohibition, so punctuation and “softeners” matter.
If the stem ends in a consonant, use -으면-eumyeon: 먹으면 안 돼요?meogeumyeon an dwaeyo? — Is it not allowed to eat?
If the stem ends in a vowel, use -면-myeon: 가면 안 돼요?gamyeon an dwaeyo? — Is it not allowed to go?
하다hada verbs become 하면hamyeon: 통화하다tonghwahada → 통화하면 안 돼요?tonghwahamyeon an dwaeyo? — Is it not allowed to make a call?
For multi-word verbs, conjugate the final verb: 사진 찍다sajin jjikda → 사진 찍으면 안 돼요?sajin jjigeumyeon an dwaeyo? — Is taking photos not allowed?
Common natural add-ons that keep it clearly “checking”:
혹시hoksi — just in case
여기(서)/이 안에서yeogi(seo)/i aneseo — location framing
괜찮을까요?gwaenchanheulkkayo? — extra soft, especially at work
Constraints (tense/subject/honorific)
Time: Most often about a future/ongoing action. You can ask about a past situation only if you mean “Was it against the rules back then?”, e.g., 어제도 들어가면 안 됐나요?eojedo deureogamyeon an dwaetnayo? — Was it not allowed to enter yesterday too?
Subject: Often about the listener or a general “people here.” For “me,” make it explicit: 제가 들어가면 안 돼요?jega deureogamyeon an dwaeyo? — Am I not allowed to go in?
Politeness: 안 돼요?an dwaeyo? is polite. For extra formality (signs, announcements, very formal workplaces), you’ll also hear 안 됩니까?an doepnikka?.
Minimal pairs (similar grammar, different meaning)
These look close, but the intent changes fast:
-(으)면 안 돼요?-(eu)myeon an dwaeyo? — checking a rule (question)
-(으)면 안 돼요.-(eu)myeon an dwaeyo. — prohibition (statement)
-아/어도 돼요?-a/eodo dwaeyo? — asking permission (“Is it okay if…?”)
-(으)면 안 될까요?-(eu)myeon an doelkkayo? — softer/indirect check (“Would it be not allowed if…?”)
A tiny punctuation trap that causes real misunderstandings:
지금 나가면 안 돼요?jigeum nagamyeon an dwaeyo? — Are we not allowed to leave now? (rule-check)
지금 나가면 안 돼요.jigeum nagamyeon an dwaeyo. — You can’t leave now. (sounds like you’re in charge)
Common mistakes (wrong → right)
I once saw a visitor in a Seoul museum get a cold reply because they asked with a flat tone, no softeners, and it sounded like a challenge. The fix is usually small.
3-way intent tree (use this before you type):
If you mean 금지geumji (you’re telling someone “don’t”): use a statement like -(으)면 안 돼요.-(eu)myeon an dwaeyo.
Signals: no ?, directive vibe, you’re correcting behavior
If you mean 규칙 확인gyuchik hwagin (you’re checking rules): use -(으)면 안 돼요?-(eu)myeon an dwaeyo? and add a softener
If you mean 조언joeon (you’re advising for their benefit): prefer a reason + alternative
Signals: “so you don’t get in trouble,” offering options, not authority
