Good to know
- 이십오 is written that way but said [이시보]: linking (final moves to the next vowel).
How 이십오 is built
이십오 is 이 (2) × 십 (10) + 오 (5). 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 스물다섯 has to be learned.
이ㅇ+ㅣ십ㅅ+ㅣ+ㅂ오ㅇ+ㅗ
