The Korean language uses two counting systems: Cardinal (also called "Native Korean" numbers) and Ordinal (also called "Sino-Korean" numbers). Cardinal numbers are used for counting quantities of things, and ordinal numbers are used for enumerating series or lists of things. Below, you will see two tables. On the left is a table showing the Native Korean numbers with their English pronunciations. On the right is a table showing the Sino-Korean numbers together with their English pronunciations. Examples of how to use each system can be found below the table.
EXAMPLES OF HOW TO USE THE KOREAN NUMBER SYSTEMS:
If you are counting as you do jumping jacks in class, you would use the Native Korean numbers (hana, dul, set, etc.).
If you are listing the Tae Geuk forms in order, you would use the Sino-Korean numbers (il, ee, sahm, etc.).
Here is an example to contrast the two systems: If you wre to say "There are 3 rooms," you would use the Pure Korean number "set." If you were to say, "Go to Room #3," you would use the Sino-Korean number "sahm."
An exception to the rule: when talking about amounts of money, such as "This item costs 1,000 won," you would use the Sino-Korean number system, NOT the Pure Korean number system. Note: "won" is the Korean form of currency--just as "dollar" is the US form of currency.
