Learning grammar is one of the most difficult things for Korean language learners. On this blog we will try to help you learn Korean grammar in the quickest and easiest way possible. This blog will be helpful for those who are studying Korean language and want to improve their grammar skills.
Today we’ll see how to form sentences with Korean grammar pattern " A/V/N ~을/ㄹ지 모르겠다 "with some example sentences.
A/V/N ~을/ㄹ지 모르겠다 is used when the speaker cannot decide to do something to be sure of something.
It is equivalent to saying " I don't know whether/if ……" in English.
It is used with adjectives, verbs and nouns.
- ~을/ㄹ지 모르겠다 when used with Adjectives and Verbs
- ~일지 모르겠다 when used with Nouns
There are three ways to use this grammar pattern :
- 을/ㄹ지 모르겠다 when used in present tense.
- 었을지/았을지/였을지 모르겠다 when used in the past tense.
- 일지 모르겠다 when used with the nouns.
