Conjugation

Verb stem + -기로 하다

If you break down the structure of -기로 하다, you can see that the verb is first turned into the -기 noun form. Then -로 is added, which represents a method or direction. You also use -(으)로 in situations where you are talking about a choice you are making, like in 이걸로 할게요, which means, “I will buy this one.” (Here, 이걸로 is short for 이것으로.) Putting everything together, the structure -기로 하다 takes on the meaning of “to decide or choose to do something in this way”.
