Long Explanation

'~(으)ㄴ/는지 모르겠다' is used in Korean when the speaker is not certain about some fact or situation. It often corresponds to 'I don't know if...' or 'I'm not sure whether...' in English. You attach ~(으)ㄴ/는지 to the verb or adjective stem, then add 모르겠다 (or 모른다, 모르겠어요, etc.) to indicate uncertainty.
