Common questions

What is the ㅅ irregular in Korean?

ㅅ drops before a vowel: 짓다 → 지어요. 15 verbs and adjectives in this dataset follow it.

When does the ㅅ 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.
