Lesson 22

In this lesson, let’s have a look at the expression -(으)ㄹ 수도 있다. In fact, this is a combination of two grammar points that we covered in our previous lessons. 

 

-(으)ㄹ 수도 있다 can be broken down into two parts: 

  1. -(으)ㄹ 수 있다 was introduced in Level 2 Lesson 17 and it means “can, to be able to”
  2. - was introduced in Level 2 Lesson 13 and it means “also, too”. 

 

When these two expressions are combined into -(으)ㄹ 수도 있다, it means “it could...” “it’s possible that...” or “it might...”. In order to understand why -(으)ㄹ 수도 있다 takes such meanings, we need to have a closer look at the expression -(으)ㄹ 수 있다 first. 

 

Basically, the word 수 is a noun that is most commonly used in this structure and means “way” “method” or “idea”. So -(으)ㄹ 수 있다 means “there is a way to do...”, “there is an idea for doing...” or “there is a possibility for doing...”. 

 

Therefore, when the meaning of -도, which is “also” or “too”, is added to this, the sentence takes the meaning of “there is also the possibility of ...”. 

 

So even though sometimes “-(으)ㄹ 수도 있다” COULD mean “to be also able to do something”, it usually means “it might” “it could” or “perhaps...”.
