How To Conjugate ㅅ Irregular Verbs (ㅅ 불규칙)
Of the seven irregular verb forms in Korean, ㅅ irregular verbs are one of the easiest to learn as they have the fewest conjugation rules to remember.
Here are the conjugation rules to follow when conjugating ㅅ irregular verbs in Korean.
Irregular ㅅ verbs and adjectives only behave irregularly when conjugated with endings that start with a vowel.
For example, endings such as 아요/어요 (present tense), ~(으)면 ( if), etc, start with a vowel, and so when these endings are attached to irregular ㅅ verbs, these verbs behave irregularly.
With other endings that start with a consonant, for example (e.g. (스)ㅂ니다, irregular ㅅ verbs and adjectives do not behave irregularly. That is, they are conjugated just the same as regular verbs.
When conjugating ㅅ irregular verbs with endings that start with a vowel, ㅅ is always dropped from the verb stem.
For example, 긋다 (to draw) + 아요/어요 = 그어요. This is because ㅅ is dropped from the verb stem before adding 아요/어요.
Vowels do not combine when conjugating ㅅ irregular verbs.
Usually when conjugating Korean words, when vowels meet, they are combined. For example, 마시다 (to drink) + 아요/어요 (present tense) = 마셔요 (NOT 마시어요). This is because the vowel ㅣ from the verb stem and the vowel ㅓ from the ending combine to make ㅕ.
However, when conjugating irregular ㅅ verbs, the vowels do not combine. Here are some examples:
짓다 + 어요 = 지어요 (NOT 져요)
낫다 + 아요 = 나아요 (NOT 나요)
ㅅ Irregular Examples
Here are some examples of ㅅ irregular verbs conjugated with some common endings. After reading these examples, if you’re not sure why they are conjugated in this way, please re-read the conjugation rules above.
|ㅅ Irregular Verb||아요/어요|
(to get well /
to be better)
As you can see in the table above, when the ㅅ irregular verbs are conjugated with endings which start with a vowel (아요/어요, (으)세요) the verb behaves irregularly. And so, ㅅ is dropped from the verb stem and the vowels do not combine.
With the ending starting with a consonant ( (스)ㅂ니다 ), the verbs do not behave irregularly. And so the verb stem does not change and ㅅ is not dropped.
ㅅ Irregular Example Sentences
