Grammar Focus:
-(으)ㄹ까요? expresses in question form the supposition of an action or state that has yet to happen. It corresponds to ‘I wonder if…’ or ‘Do you think…?’ in English. In response, -(으)ㄹ 거예요 and -(으)ㄴ/는 것 같아요 are often used. When the verb or adjective stem ends in a vowel or ㄹ, -ㄹ 까요? is used, and when the stem ends in a consonant, -을까요? is used. In the case of a past tense supposition, -았/었- is added in front of -(으)ㄹ까요? to form -았/었을까요?
