Good to know
- Before a counter word, 스물 shortens to 스무: 스무 개 (20 things), 스무 살 (20 years old).
- 스무 살 (20 years old) is a milestone in Korea: it is the age you become an adult.
How 이십 is built
이십 is 이 (2) × 십 (ten). In native Korean, the tens have their own words (열, 스물, 서른, 마흔, 쉰, 예순, 일흔, 여든, 아흔), so 스물 has to be learned.
