πŸ“Œ Two Number Systems in Korean

Korean uses two distinct number systems:
βœ… Sino-Korean (ν•œμžμ–΄ 수) – Derived from Chinese characters, used for dates, money, phone numbers, and large quantities.
βœ… Native Korean (κ³ μœ μ–΄ 수) – Used for counting objects, age, and people.

πŸ”Ή When to Use Sino-Korean Numbers:

  • Dates (e.g., years, months, days)
  • Phone numbers πŸ“ž
  • Prices (Korean won) πŸ’°
  • Minutes, seconds ⏱
  • Large numbers (above 100)

πŸ”Ή When to Use Native Korean Numbers:

  • Counting objects (books, apples, pens, etc.) πŸπŸ“š
  • Age (informally) πŸŽ‚
  • Counting people (friends, family) πŸ‘¨β€πŸ‘©β€πŸ‘§β€πŸ‘¦
  • Counting hours (time) ⏰

πŸ”’ Sino-Korean Numbers (ν•œμžμ–΄ 수)

These numbers are straightforward and follow a logical pattern.
