자주 묻는 질문Common questions
What is the 으 irregular in Korean?
The stem 으 drops before a vowel ending: 쓰다 → 써요. 47 verbs and adjectives in this dataset follow it.
When does the 으 불규칙 change happen?
In front of a vowel, and only there. The dictionary form and every consonant-initial ending — -고, -지, -습니다 — leave the stem exactly as it is; it is 아/어 and 으 endings that trigger the change.
