Good to know
- Before a counter word, 마흔둘 shortens to 마흔두: 마흔두 개 (42 things), 마흔두 살 (42 years old).
- 사십이 is written that way but said [사시비]: linking (final moves to the next vowel).
How 사십이 is built
사십이 is 사 (4) × 십 (10) + 이 (2). Once you know 1 to 10, Sino-Korean numbers build themselves. In native Korean, the tens have their own words (열, 스물, 서른, 마흔, 쉰, 예순, 일흔, 여든, 아흔), so 마흔둘 has to be learned.
