Grammar Rule in 30 Seconds

Use -(으)면 to express 'if' or 'when' by attaching it to the verb or adjective stem.

  • If the stem ends in a vowel or 'ㄹ', use -면: 가다 → 가면 (If you go).
  • If the stem ends in a consonant (except 'ㄹ'), use -으면: 먹다 → 먹으면 (If you eat).
  • For past tense, add -았/었으면 to the stem: 먹었으면 (If you had eaten).
Verb/Adj Stem + (으)면 = Conditional Clause

Overview

Korean conditionals, most commonly expressed by the connective ending -(으)면 (romanized as *-(eu)myeon*), serve as a crucial grammatical structure for linking a preceding condition or circumstance to a subsequent result or action. This ending translates broadly to if, when, or once in English, depending on the specific context. Unlike English, where conditional clauses often initiate a sentence, Korean places -(으)면 directly after the verb or adjective stem of the conditional clause, forming a tightly bound unit.
The structure [Clause A]-(으)면 [Clause B] effectively means
If/When [Clause A] occurs/is true, then [Clause B] will happen/is true.
The core linguistic function of -(으)면 is to establish a dependent relationship between two clauses. The action or state described in the second clause (Clause B) is contingent upon the fulfillment or existence of the action or state described in the first clause (Clause A). This dependency is fundamental to expressing causality, hypothetical scenarios, future plans, and general truths in Korean.
Mastering -(으)면 allows you to move beyond simple declarative sentences, enabling nuanced expressions of potentiality and consequence, which are indispensable in everyday communication.

How This Grammar Works

At its heart, -(으)면 functions as a conditional conjunction, binding two sentences together. The first clause, ending in -(으)면, expresses the condition, while the second clause expresses the outcome. This outcome can be a statement, a question, a command, or a suggestion.
The versatility of -(으)면 lies in its ability to cover a wide semantic range, often implying both if (uncertainty) and when (certainty) simultaneously.
Consider the sentence 비가 오면 집에 있을 거예요 (*biga omyeon jibe isseul geoyeyo*). Here, 비가 오면 (if/when it rains) is the condition, and 집에 있을 거예요 (I will stay home) is the consequence. The -(으)면 ending itself does not specify the certainty of the condition; rather, the context and often the tense or mood of the subsequent clause provide this clarification.
For instance, 아침이 되면 (*achimi doemyeon*) typically means When morning comes, because morning is a certainty, not a mere possibility. Conversely, 복권에 당첨되면 (*bokkwone dangcheomdoemyeon*) means
If I win the lottery,
conveying the inherent uncertainty of such an event.
Crucially, the tense of the -(으)면 clause typically remains in the present tense, even when referring to future conditions. The future tense or past tense is usually expressed in the main clause. For example, to say
If I go to Korea next year, I will visit Seoul,
you would say 내년에 한국에 가면 서울에 갈 거예요 (*naenyeone hanguge gamyeon seoure gal geoyeyo*), using 가면 (present tense conditional) not 갈 거면.
This is a significant distinction from English and is vital for natural-sounding Korean.
For example:
  • 시간이 있으면 영화를 볼까요? (*sigani isseumyeon yeonghwareul bolkkayo?*) – If you have time, shall we watch a movie? (Expressing a future possibility/suggestion).
  • 물을 끓이면 수증기가 돼요. (*mureul kkeurimyeon sujeungiga dwaeyo.*) – If you boil water, it turns into steam. (Expressing a general truth/scientific fact).
  • 졸리면 자야 해요. (*jollimyeon jaya haeyo.*) – When/If you are sleepy, you should sleep. (Expressing a general recommendation).

The formation of -(으)면 is straightforward, primarily depending on whether the verb or adjective stem ends in a vowel or a consonant (batchim).
2
1. Verb/Adjective Stem Ending in a Vowel:
3
If the stem ends in a vowel, simply attach -면.
4

16
3. Irregular Verbs/Adjectives:
17
For stems ending in (e.g., 살다, 만들다), the is typically dropped, and -면 is attached, treating it as if it were a vowel-ending stem. This is because is a liquid consonant that behaves uniquely in certain conjugations.
18

23
4. Other Irregular Verbs/Adjectives:
24
Korean has several irregular conjugations that affect -(으)면. These are consistent with how these irregulars behave with other vowel-initial endings.
25
Irregular: Stems ending in (e.g., 춥다, 돕다) change to before -(으)면.
26
| Verb/Adjective Stem | Change | + -면 | Formal (합니다체) Example | Casual (해체) Example | Meaning |

39
| 짓다 (to build) | | 지으면 | 집을 지으면 부자될 거예요. | 집을 지으면 부자될 거야. | If you build a house, you'll become rich... |
40
Irregular: Adjectives ending in (e.g., 빨갛다, 까맣다) drop and the preceding vowel changes before -(으)면. For 하얗다 (to be white), it becomes 하얗면 or often 하야면. However, for other irregulars like 빨갛다, the is dropped and is attached, with the preceding vowel often assimilating to or for certain endings, but for -(으)면 specifically, it usually retains the simple or and attaches . For example, 빨갛다 -> 빨갛면 (though 빨개지면 using 아/어지다 is more common). Generally, if the irregular is followed by a vowel, the drops. For -(으)면, it's simpler: 빨갛면 (*ppalgamyeon*), 노랗면 (*noramyeon*).
41
| Adjective Stem | + -면 | Formal (합니다체) Example | Casual (해체) Example | Meaning |
42
|:---------------|:-------|:---------------------------|:---------------------|:--------|

44
| 하얗다 (to be white) | 하얗면 | 하얗면 깨끗해 보여요. | 하얗면 깨끗해 보여. | If it's white, it looks clean... |
45
5. Nouns:
46
When -(으)면 is used with nouns, it signifies
if it is [noun]
or
if [noun] is the case.
This requires the copula 이다 (to be). The pattern is (이)라면 (*(i)ramyeon*).
47
If the noun ends in a vowel: attach -라면.
48
학생 (*haksaeng*, student) + 이라면학생이라면 (*haksaengiramyeon*) – If you are a student...
49
If the noun ends in a consonant: attach -이라면.
50
의사 (*uisa*, doctor) + 라면의사라면 (*uisaramyeon*) – If you are a doctor...
51
Example: 학생이라면 할인을 받을 수 있습니다. (*haksaengiramyeon harineul badeul su isseumnida*) – If you are a student, you can get a discount.

When To Use It

-(으)면 is incredibly versatile and appears in a wide array of contexts, from expressing general truths to offering suggestions. Its usage can be categorized into several key areas:
1. General Truths and Habitual Actions:
When describing universal facts, natural phenomena, or actions that consistently yield the same result, -(으)면 is the appropriate choice. It sets up a constant relationship where the condition always leads to the stated outcome.
  • 겨울이 오면 눈이 내려요. (*gyeouri omyeon nuni naeryeoyo.*) – When winter comes, it snows. (A natural, recurring event).
  • 버튼을 누르면 작동합니다. (*beoteuneul nureumyeon jakdonghamnida.*) – If/When you press the button, it operates. (A general function/instruction).
  • 피곤하면 커피를 마셔요. (*pigonhamyeon keopireul masyeoyo.*) – If/When I'm tired, I drink coffee. (A habitual action).
2. Future Possibilities and Plans:
This is perhaps the most common usage, where -(으)면 introduces a potential future scenario. The main clause often contains future tense markers (-(으)ㄹ 거예요, -(으)ㄹ게요) or expresses intentions, commands, or suggestions.
  • 내일 날씨가 좋으면 소풍 갈 거예요. (*naeil nalssiga joeumyeon sopung gal geoyeyo.*) – If the weather is good tomorrow, I will go on a picnic. (A plan contingent on weather).
  • 시험에 합격하면 파티를 할 거예요. (*sihome hapgyeokhamyeon patireul hal geoyeyo.*) – If I pass the exam, I will have a party. (A future possibility leading to a plan).
  • 궁금한 점이 있으시면 언제든지 물어보세요. (*gunggeumhan jeomi isseusimyeon eonjedeunji mureoboseyo.*) – If you have any questions, please ask anytime. (A polite offer/invitation).
3. Hypothetical and Counterfactual Situations (with 았/었으면):
While -(으)면 primarily uses the present tense in its clause, when expressing a wish, regret, or a hypothetical situation that is contrary to fact, it combines with the past tense auxiliary 았/었 to form 았/었으면 (*at/eosseumyeon*). This structure translates to if only... or I wish... for unrealized past events, and
if [hypothetical past/present]...
for scenarios that are not currently true.
  • 돈이 많았으면 좋겠어요. (*doni manasseumyeon jokgesseoyo.*) – If only I had a lot of money / I wish I had a lot of money. (Expressing a desire or counterfactual present).
  • 그때 말했으면 좋았을 텐데. (*geuttae malhaesseumyeon joasseul tende.*) – If I had said it then, it would have been good. (Expressing regret about a past, unrealized action).
  • 주말에 비가 안 왔으면 등산 갈 텐데. (*jumare biga an wasseumyeon deungsan gal tende.*) – If it hadn't rained on the weekend, I would have gone hiking. (Counterfactual past leading to a hypothetical outcome).
4. Conditions for Commands, Suggestions, and Requests:
-(으)면 frequently precedes clauses expressing imperatives, proposals, or requests. This setup makes the command or suggestion conditional, softer, and more polite.
  • 피곤하면 쉬세요. (*pigonhamyeon swiseyo.*) – If you are tired, please rest. (A polite command).
  • 배고프면 라면 끓여 먹자. (*baegopeumyeon ramyeon kkeuryeo meokja.*) – If you're hungry, let's cook and eat ramen. (A suggestion).
  • 더 필요한 게 있으면 말씀해주세요. (*deo piryohan ge isseumyeon malsseumhaejuseyo.*) – If there's anything else you need, please tell me. (A polite request).
5. Temporal Meaning: When (with a Prerequisite):
While -(으)ㄹ 때 is the primary ending for when (referring to a specific time), -(으)면 can also imply when in contexts where the first clause acts as a prerequisite for the second. It often carries a sense of
once [condition] is met, then [action].
  • 대학교를 졸업하면 취직할 거예요. (*daehakgyoreul joreophamyeon chwijikhal geoyeyo.*) – When/Once I graduate from university, I will get a job. (Graduation is a prerequisite for getting a job).
  • 준비가 다 되면 출발합시다. (*junbiga da doemyeon chulbalhapsida.*) – When/Once preparations are complete, let's depart. (Completion of prep is a condition for departure).

Common Mistakes

Understanding where learners typically stumble with -(으)면 can significantly improve your accuracy and fluency. These errors often arise from direct translation or confusion with similar-looking grammatical patterns.
1. Confusing -(으)면 with -(으)니까 (Because/Since):
This is one of the most frequent errors. While both connect two clauses, their logical relationship is distinct. -(으)면 establishes a condition for an outcome, whereas -(으)니까 states a reason or cause for an existing or immediately preceding event.
  • Incorrect: 비가 오니까 우산 가져가세요. (If it rains, take an umbrella.) - This sounds like you're saying "Because it's raining, take an umbrella," which implies it's *already* raining. If it's a future possibility, -(으)면 is required.
  • Correct: 비가 오면 우산 가져가세요. (*biga omyeon usan gajyeogaseyo.*) – If it rains, take an umbrella. (Future condition).
  • Correct (for cause): 비가 오니까 우산을 쓰고 가세요. (*biga onikka usaneul sseugo gaseyo.*) – Because it's raining, go with an umbrella. (Reason for present action).
Remember, -(으)니까 is for situations where the first clause is a *given fact* causing the second. -(으)면 is for *potential scenarios* that would lead to the second clause.
2. Overuse of 만약 (*manyak*) (If/Supposing):
While 만약 means if or supposing, it is often omitted in conversational Korean, as -(으)면 already conveys the conditional meaning. Using 만약 in every conditional sentence can sound overly formal or even a bit unnatural, as if you're emphasizing a highly improbable or critical condition.
  • Natural: 시간이 있으면 만나요. (*sigani isseumyeon mannayo.*) – If you have time, let's meet.
  • Less Natural (but grammatically correct): 만약 시간이 있으면 만나요.If (supposing) you have time, let's meet. (Sounds a bit like you're stressing the uncertainty of their free time).
Use 만약 when you truly want to highlight the hypothetical nature or uncertainty, or in more formal writing.
3. Incorrect Tense in the -(으)면 Clause:
As mentioned, the -(으)면 clause almost exclusively uses the present tense (verb/adjective stem + -(으)면), even if the condition refers to the future. Avoid putting future or past tense markers directly on the -(으)면 clause, unless you are using the specific 았/었으면 structure for wishes/counterfactuals.
  • Incorrect: 내일 갈 거면 전화해. (If I will go tomorrow, call me.)
  • Correct: 내일 가면 전화해. (*naeil gamyeon jeonhwahae.*) – If I go tomorrow, call me.
4. Misapplying Irregular Rules:
This irregularity is a common tripping point. Many learners mistakenly add to ending stems, creating forms like 살으면 or 만들으면.
  • Incorrect: 서울에 살으면 편해요.
  • Correct: 서울에 살면 편해요. (*seoure salmyeon peonhaeyo.*) – If you live in Seoul, it's convenient.
Always remember that for -ending stems, drops, and -면 is directly attached.
5. Confusing with -(으)ㄹ 때 (When):
While -(으)면 can mean when, -(으)ㄹ 때 specifically denotes a time period or moment when something happens, without necessarily implying a condition. It assumes the event will occur or has occurred.
  • 한국에 가면 김치를 많이 먹을 거예요. (*hanguge gamyeon gimchireul mani meogeul geoyeyo.*) – If/When I go to Korea, I will eat a lot of kimchi. (Going to Korea is a condition, may or may not happen).
  • 한국에 갈 때 김치를 많이 먹었어요. (*hanguge gal ttae gimchireul mani meogeosseoyo.*) – When I went to Korea, I ate a lot of kimchi. (You definitely went; it's a specific past time).
If the first clause is a definite event or time, -(으)ㄹ 때 is more precise. If it's a contingent event, -(으)면 is used.

Real Conversations

-(으)면 is ubiquitous in spoken and written Korean, appearing in casual chats, online interactions, and formal communications. Observing its usage in modern contexts reveals its practical applications.

1. Daily Planning and Discussions:

In everyday conversations, -(으)면 is essential for making plans, suggesting activities, or discussing potential outcomes based on conditions.

- Friend A: 주말에 비 오면 뭐 할 거야? (*jumare bi omyeon mwo hal geoya?*) – If it rains this weekend, what will you do?

- Friend B: 비 오면 집에서 영화 볼까 해. (*bi omyeon jibeseo yeonghwa bolkka hae.*) – If it rains, I'm thinking of watching a movie at home.

2. Online Interactions (Texting, Social Media, Apps):

Online, -(으)면 is frequently used for notifications, instructions, or promotional messages.

- Messaging App: 도착하면 연락 주세요! (*dochakhamyeon yeollak juseyo!*) – When you arrive, please contact me!

- Social Media Post: 이 게시물을 공유하면 추첨을 통해 선물 증정! (*i gesimureul gongyuyamyeon chuchomeul tonghae seonmul jeungjeong!*) – If you share this post, we'll give a gift through a lottery!

- Delivery App: 리뷰 남기시면 음료수 서비스 드려요. (*ribyu namgisimyeon eumryosu seobiseu deuryeoyo.*) – If you leave a review, we'll give you a free drink.

3. Work and Formal Settings:

In professional environments, -(으)면 contributes to polite requests, offers of assistance, or setting conditions for tasks.

- Email: 자료를 검토하신 후 의견이 있으시면 회신 부탁드립니다. (*jaryoreul geomtohasi hu ugyeoni isseusimyeon hoesin butakdeurimnida.*) – After reviewing the materials, if you have any opinions, please reply.

- Meeting: 문제가 발생하면 즉시 보고해주세요. (*munjega balsaenghamyeon jeuksi bogohaejuseyo.*) – If a problem occurs, please report it immediately.

4. Cultural Insight: 안 되면 as a Soft Refusal/Difficulty:

The phrase 안 되면 (*an doemyeon*), meaning "if it doesn't work out or if it's not possible," is a common and culturally nuanced expression. It often functions as a polite way to convey difficulty or a gentle refusal without being direct.

- 혹시 안 되면 다음에 다시 시도해봐요. (*hoksi an doemyeon daeume dasi sidohaebwayo.*) – If it doesn't work out (this time), try again next time.

- 그것은 좀 어려울 것 같아요. 안 되면 다른 방법을 찾아봅시다. (*geugeoseun jom eoryeoul geot gatayo. an doemyeon dareun bangbeobeul chajabopsida.*) – That seems a bit difficult. If it's not possible, let's find another way.

This phrase highlights the Korean preference for indirect communication, especially when delivering potentially negative news or discussing obstacles.

Quick FAQ

Q1: Can I use -(으)면 with 싶다 (to want to)?

Yes, absolutely. This is a very common and natural construction to express a conditional desire or intention. It allows you to say

If you want to do X, then Y.

  • 돕고 싶으면 언제든지 말해주세요. (*dopgo sipeumyeon eonjedeunji malhaejuseyo.*) – If you want to help, please tell me anytime.
  • 한국어를 배우고 싶으면 열심히 공부해야 해요. (*hangugeoreul baeugo sipeumyeon yeolsimhi gongbuhaeya haeyo.*) – If you want to learn Korean, you have to study hard.
Q2: What is the difference between 가면 and 간다면?

Both 가면 (*gamyeon*) and 간다면 (*gandamyeon*) relate to the condition of going, but 간다면 (using the structure -(느)ㄴ다면 for verbs, -(이)라면 for nouns/adjectives) adds a layer of hypotheticality, indirectness, or assumption. -(으)면 is a more general conditional.

  • 가면 연락할게. (*gamyeon yeollakalge.*) – If/When I go, I'll contact you. (Standard, direct condition).
  • 간다면 나도 갈게. (*gandamyeon nado galge.*) – If (you say/assume) you're going, I'll go too. (More emphasis on the hypothetical nature, or perhaps a conditional based on what has been said or implied).
-(느)ㄴ다면 often carries a nuance of
if it is said that...
or
if one assumes that...
making it suitable for more formal or distinctly hypothetical statements.
Q3: How do I politely say "If it's okay"?

The most common and polite way to say "If it's okay" is 괜찮으시면 (*gwaenchaneusimyeon*), derived from the adjective 괜찮다 (to be okay) plus the honorific -(으)시- and the conditional -(으)면. This phrase is invaluable for making polite requests or suggestions.

  • 괜찮으시면, 창문 좀 닫아주시겠어요? (*gwaenchaneusimyeon, changmun jom dajusigesseoyo?*) – If it's okay, would you mind closing the window?
  • 시간 괜찮으시면 잠시 이야기 좀 할 수 있을까요? (*sigan gwaenchaneusimyeon jamsi iyagi jom hal su isseulkkayo?*) – If your time is okay, could we talk for a moment?
Q4: Is -(으)면 used for unless?

-(으)면 itself does not directly translate to unless. To express unless, you typically combine -(으)면 with a negative clause, such as 지 않으면 (*ji aneumyeon*) or 안 -(으)면 (*an -(eu)myeon*), meaning "if (you) don't/won't."

  • 열심히 공부하지 않으면 시험에 떨어질 거예요. (*yeolsimhi gongbuhaji aneumyeon sihome tteoreojil geoyeyo.*) – Unless you study hard (If you don't study hard), you will fail the exam.
  • 비가 안 오면 산책 갈까요? (*biga an omyeon sanchak galkkayo?*) – Unless it rains (If it doesn't rain), shall we go for a walk?
Q5: Can -(으)면 end a sentence?

In very casual or implied speech, -(으)면 can indeed appear at the end of a sentence, leaving the consequence implied. This often conveys a sense of If only... or a frustrated, unfinished conditional thought. It's similar to trailing off in English.

  • 좀 더 일찍 왔으면... (*jom deo iljjik wasseumyeon...*) – If only I had come a bit earlier... (Implies a regret, e.g.,
    then things would be better
    ).
  • 돈만 많으면... (*donman manheumyeon...*) – If only I had a lot of money... (Implies something like
    then I could buy it
    or "then I wouldn't have this problem").
This usage is highly contextual and informal, relying on shared understanding between speakers to fill in the unstated outcome.
Q6: What are the key differences between -(으)면, -(으)거든, -(으)ㄹ 때, and -(느)ㄴ다면?
| Feature | -(으)면 | -(으)거든 | -(으)ㄹ 때 | -(느)ㄴ다면 |
|:--------|:---------------------------------------------------|:-----------------------------------------------------|:----------------------------------------------------|:----------------------------------------------------|
| Meaning | If, when, once (general conditional) | If, when (future, often for commands/suggestions) | When (specific time/period) | If (hypothetical, assumed, reported) |
| Tense | Present tense in condition clause | Future condition | Can be past, present, future | Present in condition clause |
| Certainty | Uncertain or certain, context-dependent | Future certainty (as a prerequisite) | Certain event/time | Hypothetical, assumed, indirect |
| Main Clause | Any mood (statement, question, command, suggestion) | Often command, suggestion, request | Any mood (statement, question, command, suggestion) | Any mood, but often hypothetical or formal statements |
| Formality | Neutral to formal | Conversational, informal | Neutral to formal | More formal, literary, or indirect |
| Example | 비가 오면 쉬어요. (If it rains, I rest.) | 집에 가거든 전화해. (When/If you go home, call me.) | 어렸을 때 행복했어요. (When I was young, I was happy.) | 그게 사실이라면 놀랄 거예요. (If that were true, I'd be surprised.) |
-(으)면 is the most general conditional. -(으)거든 is specific to future conditions that often precede an imperative or proposal. -(으)ㄹ 때 is purely temporal, marking a specific point or period in time.
-(느)ㄴ다면 adds a layer of hypotheticality, often based on assumption or reported speech, and is more formal or literary than -(으)면.
