모르다 conjugation

The polite forms end in 요 and suit most conversations; the formal form is for announcements, presentations and first meetings. The same form works for I, you, she or they.

How 모르다 conjugates

1. Find the stem. Take 다 off 모르다 and you are left with 모르.
2. Apply the 르 irregular pattern. The 르 becomes ㄹ러 or ㄹ라, doubling the ㄹ. That gives 몰라요.
3. Build the rest on it. The past tense adds ㅆ to the same base, giving 몰랐어요, and the table above has the future and the formal form.

Using 모르다

르-irregular: 모르다 → 몰라요 (the 르 becomes ㄹ라). One of the first irregulars every learner meets.
