How To Conjugate Irregular ㄷ Verbs (ㄷ 불규칙)
As was mentioned above, most verbs which end in ㄷ are regular verbs and so they are conjugated just like any other verbs. For example, when conjugating a verb into the present tense, with regular verbs you simply add 아요 or 어요. 닫다 is a regular verb and so in the present tense 닫다 becomes 닫아요. As you can see, the verb stem doesn’t change as this is a regular verb.
Irregular ㄷ verbs do not follow the normal conjugation rules. Here are the key things to remember when conjugating irregular ㄷ verbs.
1. Irregular verbs ending in ㄷ only behave irregularly when an ending which starts with a vowel is attached.
For example, endings such as 아요/어요 (present tense), 아서/어서 (so), -(으)면 (if), etc, start with a vowel, and so when these endings are attached to an irregular ㄷ verb, these verbs behave irregularly.
When irregular ㄷ verbs are conjugated with endings starting with a consonant, they do not behave irregularly. That is to say, they are conjugated just the same as regular verbs.
2. When conjugating irregular ㄷ verbs with endings that start with a vowel, ㄷ is replaced by ㄹ before adding the ending.
For example, the verb 듣다 (to listen) is an irregular ㄷ verb. So, if we want to conjugate this verb in the present tense (아요/어요) we must replace ㄷ with ㄹ before adding the ending 어요. 듣다 becomes 들어요 in the present tense.
3. With endings starting with 아 or 어, the vowel that comes before ㄷ determines whether 아 or 어 is used in the ending.
For example, when you want to conjugate an irregular ㄷ verb in the present tense (아요/어요) you must choose either 아요 or 어요 to add. The one you choose is determined by the vowel which comes before ㄷ in the verb stem.
If the vowel before ㄷ is 아 or 오, then the ending starting with 아 should be used.
For example, the vowel before ㄷ in 깨닫다 (to realize) is ㅏ. So, the ending starting with 아 should be used.
깨닫다 = to realize
깨달아요 = realize (present tense)
깨달았어요 = realized (past tense)
If the vowel before ㄷ is NOT 아 or 오, then the ending starting with 어 should be used.
For example, the vowel before ㄷ in the verb 듣다 (to listen) is not ㅏ or ㅓ. So, we must choose the ending starting with 어.
듣다 = to listen
들어요 = listen (present tense)
들었어요 = listened (past tense)
