Hangul's "Han" Didn't Mean "Great." It Meant Korea.

The Korean alphabet turns 580 this week. Its name dates only to the 1910s.

In Three Lines

Korea's alphabet was not called Hangul until the 1910s, nearly five centuries after King Sejong introduced it.
The "han" came from the country's name, and the second syllable was chosen so the word would not sound like the term for Chinese writing.
Scholars still argue over who coined it. The record is clearer on why a new name was needed.

On Friday, South Korea marks Hangul Day, a national holiday for its alphabet. This year marks the 580th anniversary of the script's promulgation and the centennial of the holiday's first observance, under a different name.

Ask a Korean what "Hangul" means and the likely answer is "the great script" or "the one and only script." That is how it is taught in school, and it sounds right, because in older Korean "han" could mean great or one. But the people who first put the word on paper had something else in mind. They were thinking of the nameplate on their country's door.

The King Called It Something Else

King Sejong introduced the alphabet in 1446 as Hunminjeongeum, "the correct sounds for instructing the people." The name did not stick. For most of the next five centuries, the script was called eonmun, the vernacular writing. Classical Chinese, meanwhile, was jinseo, "true writing," which left eonmun a step below. Sejong himself used the word eonmun, though, and some scholars argue it was not meant as a slight at first.

After the reforms of 1894, the government made the script the basis of official laws. The script and the language took on prouder names: gungmun, "the national script," and gugeo, "the national language." Those names kept that meaning for less than 20 years.

In 1911, "National Language" Came to Mean Japanese

Japan annexed Korea on Aug. 29, 1910, and took its name along with its sovereignty. The country had been called Daehan since 1897. Japan renamed it Joseon, after the old dynasty.

Daehan had been King Gojong's choice. In October 1897, he told his ministers that Korea was the land of the Three Han, ancient states on the peninsula, and that it had long since been united. It could therefore be called Daehan, the Great Han.

On Aug. 23, 1911, Japan promulgated an education ordinance for its new colony. In its schools, the subject called "national language" now meant Japanese. Korean was taught separately, under the label "the Joseon language."

The linguist Ju Si-gyeong led a small society in Seoul devoted to the study of Korean. It had been founded in 1908 as the National Language Research Society. On Sept. 3, 11 days after the ordinance, it dropped "national language" from its name. The new name was a native Korean coinage, Baedal Malgeul Modeum, roughly "the gathering for the speech and script of our people."

11 days

From Japan's colonial education ordinance (Aug. 23, 1911) to a Korean scholars' society removing "national language" from its name (Sept. 3)

No surviving document links the two dates. Only the interval survives.

One Syllable on a Certificate

Ju had been looking for a native replacement for "national language" even before annexation. In June 1910, writing in a society bulletin, he used hannara mal and hannara geul, "the speech and script of the Han nation." The han was the han of Daehan.

With annexation, that nameplate was changed to Joseon. What Ju and his students did over the next few years looks a lot like a search for somewhere to keep one syllable of the old one.

Ko Young-kun, an emeritus professor at Seoul National University, catalogued the society's certificates, and they trace that search. A diploma issued in April 1911 bore a seal reading "the place for learning Han mal," the Han language. On the same certificate, the name of the issuing body left out the "Han." Ko reads that as an effort to avoid the notice of colonial officials.

By March 1912, "Han mal" had disappeared from the certificates, replaced by "Joseon mal." The school was listed as the Joseon Language Institute.

On March 23, 1913, the society held an extraordinary meeting at the Boseong School in Seoul. Fourteen members attended, according to the minutes. They voted to rename the group Hangeulmo, the Hangul Society. The "han" that had vanished from the 1912 certificate was back. The minutes are among the earliest dated documents in which the word Hangul appears.

The nameplate now said Joseon. The question was where to keep the one syllable left over.

Why Not Just "Hanmun"?

If the goal was "the script of Han," why not simply 韓文, pronounced hanmun? It is a fair question, and the answer lies in the sound.

Kwon Deok-gyu, one of Ju's students, explained it in a 1933 Korean-language textbook written for radio lessons in Seoul. Hangul, he wrote, was 韓文 read in native Korean. Spelled out by sound, 韓文 would become hanmun, which is exactly how Koreans pronounce 漢文, the word for classical Chinese writing.

A name for the Korean alphabet that sounded like the name for classical Chinese would not do. So the first syllable stayed, and the second became geul, the native Korean word for writing.

And "the great script"? An old Korean verb meaning "to be great" takes the form han when it modifies a noun. The sounds matched, and over time the meanings merged. Choe Hyeon-bae, a grammarian who had studied under Ju, defined the han in Hangul as "one, great and correct" in a 1942 book. Ko and Park Kap-soo, another Seoul National University scholar, both regard that reading as a later gloss rather than the original sense.

Who Coined It Is Still Disputed

The natural next question is who came up with the word. Ju is the most common answer, and Ko defends it, pointing to the trail of names from hannara geul to Hangeulmo and to Kwon's account.

A rival account credits Choe Nam-seon, a publisher who worked with Ju on a dictionary at a society Choe ran to reprint classic texts. That claim first appeared in print in 1936, and the linguist Lim Hong-bin has argued that it remains plausible. Choe himself wrote in 1946 that the han meant both "great" and the han of Korea. A third claim points to the journalist Yi Jong-il, whose 1898 diary appears to use the word. Critics argue that the passage was added later.

A 2021 study by Jieun Kiaer of the University of Oxford and Shin Jiyoung of Korea University concluded that no single originator can be identified. Several names for the script, it found, coexisted until about 1927. It also called the 1910 annexation the most decisive factor in the name's creation. Scholars split over who coined the word. On why it was needed, the scholars cited here largely converge.

From "Gagya Day" to Hangul Day

The name spread slowly. By Ko's account, its earliest confirmed appearance in a magazine is the March 1914 issue of Aideulboi, a children's monthly published by Choe. Ju died that July.

On Nov. 4, 1926, the Korean Language Research Society, rebuilt by Ju's students, joined the group Sinminsa to mark the 480th anniversary of the alphabet's promulgation. The ceremony was held at Sikdowon, a restaurant in Seoul, and drew several hundred people. The occasion was called Gagya Day, after "ga, gya, geo, gyeo," the chant people used to learn the letters.

A coterie journal titled Hangul appeared the following February. On Nov. 11, 1928, Gagya Day became Hangul Day, 15 years after the 14 members had renamed their society. The date moved, too. It was first observed on the 29th day of the ninth lunar month, and Oct. 9 was fixed in 1945, after an original copy of the 1446 text was found in 1940.

After liberation, the name divided along with the peninsula. North Korea's 1948 spelling rules referred to "Joseon language letters" rather than Hangul letters. Writing in 2003, Ko said he could find no official North Korean use of the word after 1954. He attributed that to the han being the han of the South's official name, Daehan Minguk. The 14 members at the Boseong School kept one syllable from a nameplate that had been taken down. It outlasted the empire it came from. On Friday, millions of people will say it.
