Learning Numbers in Korean
What makes Korean numbers challenging
Two complete number systems (Sino-Korean and native Korean) must be used in the right contexts — using the wrong one sounds unnatural. Native Korean numbers change form when combined with counters (hana becomes han, dul becomes du, set becomes se). Like Japanese, Korean groups large numbers by 10,000 (만/man), requiring English speakers to mentally regroup. Sino-Korean numbers are short monosyllables (il, i, sam) that can blur together at speed. Knowing which system to use (Sino for dates/money/phone, native for counting/age) is essential.
Tips for learning Korean numbers
Learn Sino-Korean numbers first — they are simpler, shorter, and cover phone numbers, dates, prices, and addresses. Then learn native Korean 1-99 for counting objects and telling age. Practice the man (10,000) grouping system with Korean won amounts (prices are usually in thousands or ten-thousands). For phone numbers, Sino-Korean is always used. KakaoTalk conversations often include numbers, making them good practice material.
