Korean numerals

The Korean language has two regularly used sets of numerals, a Sino-Korean system and a native Korean system.

Construction

For both native and Sino-Korean numerals, the teens (11 through 19) are represented by a combination of tens and the ones places. For instance, 15 would be sib-o (십오), but not usually il-sib-o in the Sino-Korean system, and yeol-daseot (열다섯) in native Korean. Twenty through ninety are likewise represented in this place-holding manner in the Sino-Korean system, while Native Korean has its own unique set of words, as can be seen in the chart below. The grouping of large numbers in Korean follow the Chinese tradition of myriads (10000) rather than thousands (1000). The Sino-Korean system is nearly entirely based on the Chinese numerals.

The distinction between the two numeral systems is very important. Everything that can be counted will use one of the two systems, but seldom both. Sino-Korean words are sometimes used to mark ordinal usage: yeol beon (열 번) means "ten times" while sip beon (십(十) 번(番)) means "number ten."

When denoting the age of a person, one will usually use sal (살) for the native Korean numerals, and se (세) for Sino-Korean. For example, seu-mul da-seot sal (스물다섯 살) and i-sib-o se (이십오 세) both mean 'twenty-five-year-old'. See also East Asian age reckoning.

The Sino-Korean numerals are used to denote the minute of time. For example, sam-sib-o bun (삼십오 분) means "__:35" or "thirty-five minutes." The native Korean numerals are used for the hours in the 12-hour system and for the hours 0:00 to 12:00 in the 24-hour system. The hours 13:00 to 24:00 in the 24-hour system are only denoted using the Sino-Korean numerals. For example, se si (세 시) means '03:00' or '3:00 a.m./p.m.' and sip-chil si (십칠 시) means '17:00'.

For counting above 100, Sino-Korean words are used, sometimes in combination: 101 can be baek-hana or baeg-il.

Some of the native numbers take a different form in front of measure words:

Number	Native Korean cardinals			Attributive forms of native Korean cardinals
	Hangul	McCune-Reischauer	Revised	Hangul	McCune-Reischauer	Revised
1	하나	hana	hana	한	han	han
2	둘	tul	dul	두	tu	du
3	셋	set	set	세	se	se
4	넷	net	net	네	ne	ne
20	스물	sŭmul	seumul	스무	sŭmu	seumu

The descriptive forms for 1, 2, 3, 4, and 20 are formed by "dropping the last letter" from the original native cardinal, so to speak. Examples:

• 한 번 han beon ("once")
• 두 개 du gae ("two things")
• 세 시 se si ("three o'clock")
• 네 명 ne myeong ("four people")
• 스무 마리 seumu mari ("twenty animals")

Something similar also occur in some Sino-Korean cardinals:

• 오뉴월 onyuwol ("May and June")
• 유월 yuwol ("June")
• 시월 siwol ("October")

The cardinals for three and four have alternatives forms in front of some measure words:

• 석 달 seok dal ("three months")
• 넉 잔 neok jan ("four cups")

Pronunciation

The initial consonants of measure words and numbers following the native cardinals 여덟 ("eight", only when the ㅂ is not pronounced) and 열 ("ten") become tensed consonants when possible. Thus for example:

• 열 셋 yeolset (thirteen) is pronounced like [열쎗] yeolsset
• 여덟 권 yeodeolgwon (eight (books)) is pronounced like [여덜꿘] yeodeolkkwon

Several numerals have long vowels, namely 둘 (two), 셋 (three) and 넷 (four), but these become short when combined with other numerals / nouns (such as in twelve, thirteen, fourteen and so on).

The usual liaison and consonant-tensing rules apply, so for example, 예순 여섯 (sixty-six) is pronounced like [예순녀섣] (yesunnyeoseot) and 칠십 chilsip (seventy) is pronounced like [칠씹] chilssip.

Constant Suffixes used in Sino-Korean ordinal numerals

번(番),호(號),차(次), and 회(回)are costantly used with Sino-Korean or Arabic ordinal numerals. For example, 이호선(二號線) is Line Number Two in metropolitan subway system. 37번국도(37番國道) is Highway Number 37. They can not be used interchangeably. 906호(號) is 'Apt #906' in mailing address. 906 without 호 is not used in spoken Korean to imply apartment number or office suite #. Special prefix 제(第) is usually used in combination with suffixes to designate a specific event in sequential things such as the Olympics.

Special Alternatives used in Booking

In commerce or financial sector, some hanja for each sino-Korean numbers are replaced by alternative ones to prevent ambiguity or retouching.

two	이	二	貳
three	삼	三	參
seven	칠	七	柒
ten	십	十	拾
hundred	백	百	佰
thousand	천	千	仟

Notes

• Template:Fnb These names are considered archaic, and are not used.
• Template:Fnb The numbers higher than 10²⁰ (hae) are not usually used and are considered to be only conceptual by many people.
• Template:Fnb The names for these numbers are from Buddhist texts; they are not usually used and are considered to be only conceptual by many people. Dictionaries sometimes disagree on which numbers the names represent.
