Introduction
One rhetoric that is often employed by Korean Hangul supremacists against Hanja is that Chinese characters are somehow a Japanese legacy. Just to give to examples, the statistic that Sino-Korean words account for 60-70% of the Korean vocabulary is routinely denounced as a Japanese fabrication implanted by the Japanese colonial administration and Hanja-Hangul mixed script is often condemned as a Japanese creation imposed upon the Korean populace — presumably because of its similarity to modern Japanese orthography. While both are demonstrably false, this type of rhetoric is so common that one could easily come away with the impression that Hanja is a Japanese creation from reading their materials.
More distressingly, these baseless assertions can be found from people of relatively respectable positions in Korean society. The head of the Hangul Society (한글학회), one of the most influential and well-established Korean language associations, for example, shares similar sentiments:
한자병기는 일제가 심어 놓은 민족의식 말살 교육정책의 찌꺼기. 지금 일본이 큰소리치는 것은 한국을 너무 잘 알기 때문이다. 일본이 가르친 대로의 친일의 뿌리가 득세하고 있기 때문이다. 한글 관련 사업을 좀 해보려고 하면 친일세력들이 들어와서 판을 흐트려 놓는다…
Hanja-Hangul mixed script is a leftover of the educational policy planted by the Japanese to obliterate our racial identity. Right now, the Japanese shout so loudly because they know Korea very well. It is because the pro-Japanese collaborators who have done as the Japanese have taught them have gained power. If you intend to work on Hangul-related manners, these powerful pro-Japanese collaborators will shake you down…
Remember, this is not some random troll in a dark corner of the Internet. This is the head of a major Korean language association spewing conspiratorial rantings. And he is not an isolated case. Hangul supremacists can be found at protests screaming at the top of their longs accusing those who want to expand Hanja education as being pro-Japanese collaborators
Ironically, however, Hangul supremacists will not condemn actual collaborators that they perceive contributed to the advancement of Hangul. No, they brazenly genuflect in front of them. For instance, they praise Yi Gwangsu (李光洙, 이광수, 1892-1950) for being the “Father of Modern Korean Literature” and one of the earliest proponents of the “pure Korean script.” Hangul supremacists happily overlook the fact that he was a zealous supporter of Japanese policies for assimilating Koreans. Even hyper-nationalist North Korea does not mind his collaborations with the Japanese colonial government, and has enshrined him at a cemetery in Pyongyang with other Korean independence activists.
This dissonance partly has to do with their belief that Hangul is an embodiment of “pure” Korean-ness. In their world view, they cannot fathom that the Japanese would have had any hand in the script. Any efforts to aid Hangul is deified and any attempts at expanding Hanja is unforgivable perfidy.
A Brief History of the Development of Korean Spelling Rules
But Hangul too has been heavily influenced by Japanese colonial rule. To get of sense of the degree of influence, today’s Korean spelling rules are almost identical from the ones promulgated by the Japanese colonial General Government. (While this fact might be lost on many Hangul supremacists, most Korean sources on this subject do not deny this.) A look at how Korean spelling developed from its inception through the early modern period will make this point evident.

A Chinese character dictionary arranged by tone and rime, the Proper Rimes of the Eastern Country (東國正韻, 동국정운) was one of the very first works published in the Korean alphabet. The still-in-use ㅉ and now-obsolete ㆆ (glottal stop) were originally intended for transcribing Korean and Mandarin pronunciations of Chinese characters. (Source)
Korean Spelling from King Sejong to the Late 19th Century
In 1446, King Sejong introduced Hangul with the publication of Proper Sounds to Instruct the People (訓民正音, 훈민정음). This work laid out twenty-eight letters. In order, they were:
- Consonants (17): ㄱ (g), ㅋ (k), ㆁ (ng), ㄷ (d), ㅌ (t), ㄴ (n), ㅂ (b), ㅍ (p), ㅁ (m), ㅈ (j), ㅊ (ch), ㅅ (s), ㆆ (ʔ, glottal stop), ㅎ (h), ㅇ (null), ㄹ (r/l), and ㅿ (z).
- Vowels (11): ㆍ (aw), ㅡ (eu), ㅣ(i), ㅗ (o), ㅏ (a), ㅜ (u), ㅓ (eo), ㅛ (yo), ㅑ (ya), ㅠ (yu), and ㅕ (yeo)
The work also explicated how each letter is to be pronounced and how the letters are to be combined to form syllable blocks. It even specified provisions for sounds that did not exist in native Korean, but Sino-Korean and vernacular Chinese (e.g., ㅱ for “w”). The Proper Sounds, however, did not give any detailed spelling rules. Its examples assumed that Korean would be spelled phonemically using the new alphabet (i.e., how they sounded). The only concrete spelling rule it proscribed was the Eight Terminal Consonants Rule (八終聲可足用, 팔종성가족용). Under this rule, only ㄱ, ㆁ, ㄷ, ㄴ, ㅂ, ㅁ, ㅅ, and ㄹ were to be used in the terminal position of a syllable (받침).
After the Proper Sounds, the next seminal work on Korean spelling the Collection of Chinese Characters to Teach the Ignorant (訓蒙字會, 훈몽자회) published in 1527 by Choe Sejin (崔世珍, 최세진, 1468-1542). The Collection of Characters systematically listed some 3,360 Chinese characters by their Korean pronunciations and meanings. Although published eighty-one years later, the work laid out different spelling rules than those of the Proper Sounds. For example, the letter ㆆ had dropped out, the distinction between ㅇ and ㆁ was lost, and some of the specific provisions for Sino-Korean and vernacular Chinese sounds were absent. It also added new rules and provisions to Korean, such as listing the alphabet in a different order with names:
- Voiceless Consonants: ㄱ(其役, 기역), ㄴ(尼隱, 니은),ㄷ(池末, 디귿), ㄹ(利乙, 리을), ㅁ(眉音, 미음), ㅂ(非邑, 비읍), ㅅ(時衣, 시옷), and ㆁ(異凝, 이응)
- Voiced Consonants: ㅋ(箕, 키), ㅌ(治, 티), ㅍ(皮, 피), ㅈ(之, 지), ㅊ(齒, 치), ㅿ(而, ㅿㅣ), ㅇ(伊, 이), and ㅎ(屎, 히)
- Vowels: ㅏ(阿, 아), ㅑ(也, 야), ㅓ(於, 어), ㅕ(余, 여), ㅗ(吾, 오), ㅛ(要, 요), ㅜ(牛, 우), ㅠ(由, 유), ㅡ(應, 응),ㅣ(伊, 이), and · (思, ㅅ·)
The Collection of Characters, however, maintained some of the rules as laid out in the Proper Sounds. It kept the Eight Terminal Consonants Rule and still assumed that Korean was to be spelled phonemically.
In the subsequent three centuries, Korean spelling rules only saw incremental changes, largely aligning with changes in how Korean was spoken. Some of the changes included:
- Disuse of the letter ㅿ and ㆁ
- Adding of ㅺ, ㅼ, ㅽ, ㅾ, and ㅄ for tense sounds (된소리), which probably did not exist in 15th century Korean (while ㄲ, ㄸ, ㅃ, ㅆ, and ㅉ did exist, they did not originally denote those sounds)
- Disuse of ㄷ as a terminal sound (solely using ㅅ) by a substantial number of Korean writers
One characteristic that did not change was that Korean throughout this period was still spelled phonemically, although there were discrepancies between the spelling and pronunciation.

Published in 1908, the Book for Teaching Children (兒學編, 아학편) listed definitions of Chinese characters in Korean, Japanese, and English and also pronunciations of the Japanese, Mandarin, and English words in Hangul. Note the use of “ᅋ” (f) to spell “father,” “female,” and “wife.” Koreans today often make fun of themselves not being able to spell (or pronounce) English “f” and “v” sounds. Many might be shocked to find out that their great-grandparents’ Hangul allowed for spelling such sounds. (Source)
1894, Hangul Finally Becomes the National Script of Korea
Phonemic spelling of Korean, however, did not eliminate ambiguity. The same word could be spelled many different ways. This actually made Hangul-only texts more difficult to read than mixed script texts. For example, the word 덮으면 (“if one covers”) in modern spelling could be spelled at least three ways under the conventional spelling of this time: 더퍼면, 덥허면, 덥프면. How a Korean word was spelled was up to the whims of the individual printer for that particular day or hour.
With Hangul becoming the “National Script” (國字, 국자) of Korea in 1894, the necessity of a clear, set spelling rules became soon apparent. This need was compounded by the fact that there were several, different attempts at formulating such rules by private individuals. One notable individual was a doctor named Ji Seokyeong (池錫永, 지석영, 1855-1935) who submitted his own rules to the court. His proposals (新訂國文, 신정국문) included:
- Spelling of tense consonants with ㄲ, ㄸ, ㅃ, ㅆ, and ㅉ
- Adding ᅄ and ᅋ to denote “v” and “f” sounds
- Replacing arae a (·) (아래 아) with =
The controversy grew. Some wanted Korean to be spelled morphophonemically (somewhat phonetic spelling reflective of the underlying etymological root). Others wanted Korean to be spelled like the European languages in a string. One notable development that was widely adopted and stuck was word spacing.
In 1907, the Korean government (now a protectorate of Japan) responded by establishing the National Script Research Committee (國文硏究所, 국문연구소) to examine this problem. Its members, some of whom were pro-Japanese collaborators, met several times to discuss standardization of Korean spelling. In 1909, they laid out their plans in the National Script Research Committee’s Proposals (國文硏究議定案, 국문연구의정안). At the time, these were considered radical:
- Maintenance of the formation of letters into syllable blocks
- Not restoring the use of obsolete consonants (ㆁ, ㆆ, ㅿ, ◇ , ㅱ, ㅸ, ㆄ, and ㅹ )
- Adoption of spelling of tense consonant as ㄲ, ㄸ, ㅃ , ㅆ, and ㅉ
- Maintenance of the letter ㆍ
- Adding a dot to the side of a syllable to indicate vowel length
- Allowing the use of ㅈ, ㅊ, ㅋ, ㅌ, ㅍ, and ㅎ as terminal consonants
- Adoption of the names for the consonant letters as 이응, 기윽, 니은, 디읃, 리을, 미음, 비읍, 시읏, 지읒, 히읗, 키읔, 티읕, 피읖, 치읓
- Adoption of the order of consonants as ㆁ, ㄱ, ㄴ, ㄷ, ㄹ, ㅁ , ㅂ, ㅅ, ㅈ, ㅎ, ㅋ, ㅌ, ㅍ, ㅊ
- Adoption of the order of vowels as ㅏ, ㅑ, ㅓ, ㅕ , ㅗ , ㅛ , ㅜ, ㅠ, ㅡ , ㅣ, ㆍ
These spelling rules never officially adopted. Within months of the release of the 1909 Proposals, Korea was annexed by Japan. The debate over Korean orthography would, however, continue. Read More
