Now it’s time to learn about irregular verbs.
Irregular verbs don’t follow the regular present tense conjugations. There are four different verb endings you should be aware of: ㅂ,르,ㄷ,ㅅ.
1. If a verb ends in ‘ㅂ’, first if the vowel before the ㅂ is 오, then we remove the ㅂ, and add 오, else if the vowel before the ㅂ is not 오, then we remove the ㅂ and add 우. Then we conjugate it normally according to the regular rules.
어렵다 = 어려 + 우 + 어요 = 어려워요.
돕다 = 도 + 오 + 아요 = 도와요.
2. If a verb ends in ‘르’, first we remove the 르, and add ㄹ to the last vowel before it, then we add an extra ㄹ and then we conjugate it normally according to the regular rules.
다르다 = 달 + ㄹ + 아요 = 달라요.
모르다 = 몰 + ㄹ + 아요 = 몰라요.
3. If a verb ends in ‘ㄷ’, and it is followed by a vowel, first we change the ㄷ to a ㄹ and then we conjugate it normally according to the regular rules.
Only some ㄷ verbs follow this rule. Others conjugate normally.
걷다 = 걸 + 어요 = 걸어요.
듣다 = 들 + 어요 = 들어요.
4. If a verb ends in ‘ㅅ’, and it is followed by a vowel, we remove the ㅅ and then we conjugate it normally according to the regular rules.
Only some ㅅ verbs follow this rule. Others conjugate normally.
잇다 = 이 + 어요 = 이어요.
짓다 = 지 + 어요 = 지어요.
