In this lesson, you will learn how to attach ~ㄹ/을수록 to the end of a clause. A rather advanced grammatical principle, but something that you should be able to grasp easily. Let’s get started.



As One Situation Changes, Another Situation Changes: ~/을수록

~ㄹ/을수록 is attached to verbs, adjectives and 이다 to indicate that – as one situation changes to some degree, another situation is affected and also changes to that degree. Let’s start by looking at a simple sentence to illustrate this meaning:

공부를 할수록 똑똑해요

In this sentence, ~ㄹ/을수록 is attached to 공부하다. The speaker is indicating that the degree in which one studies will affect the degree in which one is smart. A common English translation when ~ㄹ/을수록 is used in a sentence is “As….” For example:

공부를 할수록 똑똑해요 = As you study, you get smart

Implied in the meaning of ~ㄹ/을수록 is the idea that – if one studies to a certain degree, they get smart to that degree – but if one studies even more, they get even smarter. Therefore, it might be better to translate the sentence above in either of the following ways:

공부를 할수록 똑똑해요 = As you study more, you get smarter, or
공부를 할수록 똑똑해요 = The more you study, the smarter you get

You can use words like “많이” and “더” in these sentences, but it isn’t necessary. For example:

많이 공부를 할수록 더 똑똑해요 = As you study more, you get smarter
많이 공부를 할수록 더 똑똑해요 = The more you study, the smarter you get

Although “많이” and “더” are included in the sentences immediately above, their meanings are the same as the sentence presented earlier without them. As I mentioned, this meaning is already implied in the meaning of ~ㄹ/을수록. Although not necessary, it is common for Korean people to include these words.

It is also common to attach ~아/어지다 (Lesson 18) to the final word if it is an adjective. For example:

많이 공부를 할수록 더 똑똑해져요 = As you study more, you get smarter

I’m not able to express any difference in meaning when using ~아/어지다 or not in these examples. Again, the meaning of “more” or “getting…” is already implied in the meaning of ~ㄹ/을수록, so it isn’t necessary. That being said, there are times when adding ~아/어지다 is inappropriate. For example, look at the following sentence, which does not have ~아/어지다:

아침 일찍 과일을 살수록 과일이 더 싱싱해요
= The earlier you buy fruit in the morning, the fresher the fruit will be

Let me explain the difference between the following sentences:

공부를 할수록 똑똑해져요
아침 일찍 과일을 살수록 과일이 더 싱싱해요

In the first sentence, ~아/어지다 is used. If you think about the subject of this sentence – people in general – people can get smarter. However, in the second sentence, the fruit itself isn’t getting fresher. Only the situation of “going early” will allow one to get fresher fruits – but the fruit isn’t actually getting fresher.

Below you can see a similar example where ~아/어지다 would be inappropriate:

바나나가 초록색일수록 딱딱해요 = The greener bananas are, the harder they are

In this example, the bananas themselves don’t actually get harder. The speaker is just expressing the notion that the degree in which a banana is green will affect the degree in which it is hard. However, you will not see a banana actually get greener and then, because of that, get harder.

The sentence above shows ~ㄹ/을수록 added to 이다. You have also seen it added to verbs. It is also possible to add it to adjectives. For example:

여자들은 예쁠수록 인기가 많아요
여자들은 예쁠수록 인기가 많아져요
= As girls get prettier, they get more popular

You can also create a negative sentence to indicate that as a situation happens less, some other situation will be affected. For example:

일을 안 할수록 시간이 많아요
일을 안 할수록 시간이 많아져요
= As you work less, you will have more free time


Let’s look at a bunch of example sentences using ~ㄹ/을수록:

발톱이 길어질수록 아파요
= The longer my toenails get, the more they hurt

어두워질수록 야경이 예뻐요
= As it gets darker, the night view gets prettier

가방에 물건을 넣을수록 무거워져요
= As you put more things/items in my bag, the heavier it gets

친구들을 자주 만날수록 행복해져요
= The more often you meet friends, the happier you get

휘발유가 비쌀수록 교통비가 비싸져요
= The more expensive gasoline is, the more expensive transportation costs will be

선진국이 아닐수록 소매치기가 많아요
= As a country is less developed, there is more pick pocketing
