Good to know
- Before a counter word, 아흔하나 shortens to 아흔한: 아흔한 개 (91 things), 아흔한 살 (91 years old).
- 구십일 is written that way but said [구시빌]: linking (final moves to the next vowel).
How 구십일 is built
구십일 is 구 (9) × 십 (10) + 일 (1). 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 아흔하나 has to be learned.
구ㄱ+ㅜ십ㅅ+ㅣ+ㅂ일ㅇ+ㅣ+ㄹ
