(으)면 되다 grammar

Basically,되다 means to be okay or to be all right. It is attached to many words and make different meanings.(으)면 되다 you just have to/ have only to…., (으)면 안되다 prohibition, 어/아/야 되다- have to/ must, 어/아 도 되다- taking permission these are sentence endings conjugated from 되다.

V + (으)면 되다 is used to say it’s enough to/you just have to…. in English. In other words V + (으)면 되다 shows the minimum requirement that is required to achieve a result.

In simple words (으)면 되다 means if you do this everything will be okay. Suppose you have completed almost all of your task and only one task remains and another person says if you do this (remaining task) everything will be okay, in this case, he/ she has to say (으)면 되다 in Korean.

If you have to say something is enough in Korean you can use this grammar. ‘(으)면 되다’ attaches after an adjective/verb stem. (으)면 되다 is the combination of ‘(으)면’ and ‘되다’.

Let’s look at some examples for better understanding of today’s grammar (으)면 되다.

Example 1 : 

Suppose you are planning to go abroad and you got a visa and bought a ticket also. You only need to pack luggage then in this case you can say 저는 짐만 싸면 돼요.

Example 2 : 

Person A: 우리 내일 공원에 몇 시까지 와야 돼요?” What time should we come to the park tomorrow?

Person B: “8시 30분에 출발할 거예요.” We’re leaving at 8:30.

“그러니까 8시까지 오면 돼요.” So, you can come by 8.

‘내일 공원에 8시까지 오면 돼요.’ You can come to the park by 8. Here, ‘오면 돼요’ is a combination of the verb ‘오다 (to come) and ‘면 되다.’

So it means if you arrive at the park by 8 or if you come to the park by 8, it’s enough.

Example 3: 

‘시험을 통과하려면 40점만 넘으면 돼요.’ You only need to get over 40 points to pass the exam.

‘넘으면 돼요’ is a combination of the verb ‘넘다 (to pass)’ and 면 되다.

100 points is the full score and if you pass 40 points, you can pass the exam. So it means ‘Over 70 points are enough.’

‘시험을 통과하려면 70점만 넘으면 돼요.’ You only need to get over 40 points to pass the exam.

(으)면 되다 Rule

Now we’re going to look at the combination information.

When an adjective/verb stem has the final consonant, you can use ‘으면 되다.’ For example, when you look at the verb ‘먹다 (to eat)

Remove ‘다’. Then there is the final consonant. Then you can add ‘으면 되다.’ So it becomes ‘먹으면 되다’

Let’s look at the adjective ‘좋다’ (to be good).’

Remove ‘다’. Then there is the final consonant.

Then you can add ‘으면 되다.’ So it becomes ‘좋으면 되다.’

On the other hand, when an adjective/verb does not have the final consonant, ‘면 되다’ is used.

For example, when you look at the verb ‘오다 (to come),’ remove ‘다.’ Then there is no final consonant. Then you can use ‘면 되다.’ So it becomes ‘오면 되다.’ 

Let’s look at the adjective ‘크다 (to be big)’.

Remove ‘다’. Then there is no final consonant. You can use ‘면 되다.’ So it becomes ‘크면 되다.’

Lastly, when an adjective/verb stem ends with the final consonant ‘ㄹ,’ ‘면 되다’ is used. For example, when you look at the verb 만들다 (to make), remove ‘다’. Then the final consonant is ‘ㄹ’ before ‘다’. So you can add ‘면 되다.’ So it becomes ‘만들면 되다.’

Let’s look at the adjective ‘길다 (to be long)’.

Remove ‘다’. Then the final consonant is ‘ㄹ’ before ‘다’.

You can use ‘면 되다.’

So it becomes ‘길면 되다.’

아야/어야/해야 되다 vs 으면/면 되다

Now let’s compare ‘아야/어야/해야 되다’ with ‘으면/면 되다.’ ‘아야/어야/해야 되다’ expresses ‘one must/should do something’ that has the meaning of obligation or necessity.

On the other hand, ‘(으)면 되다’ has the meaning that if a certain condition is fulfilled, it’s enough.

So ‘(으)면 되다’ does not empathize obligation or necessity.

Let’s look at some examples.

“내일 회사에 몇 시까지 와야 돼요?” What time should I come to the company tomorrow?

Answer using ‘아야/어야/해야 되다’ first.

‘9시까지 와야 돼요.’ You have to be here by 9.

This expression indicates an obligation.

It’s your obligation to be here by 9:00. You should come by 9.

On the other hand, when you answer using ‘(으)면 되다’, you can answer

‘9시까지 오면 돼요.’ You can come by 9.

This expression means ‘9 o’clock is enough’.

It doesn’t emphasize obligation or necessity.

‘9시까지 오면 돼요.’ You can come by 9.

Let’s practice by looking at some more examples.
