TTMIK Level 9 Lesson 18 – -(으)ㄹ까 보다

In this lesson, we are looking at how -(으)ㄹ까 보다 is used in a sentence. As you’ve learned from Level 3 Lesson 4, when you add the ending -(으)ㄹ까 after a verb stem, it can express an assumption (e.g. 내일 비가 올까요? = Do you think it will rain tomorrow?). With  -(으)ㄹ까 보다, an assumption is also implied, but you can also express concern, the reason for a decision, or an inclination to do something.
