Lee Hee-seung (June 9, 1896 – November 27, 1989) was a Korean linguist, poet, and essayist. His courtesy name was Seongse (聖世); his pen name was Ilseok (一石).
Born in Poil-ri, Uigok-myeon,[1] Gwangju-gun, Joseon (now Poil-dong, Uiwang-si, South Korea), he passed through Gaepung-gun and spent his early childhood in Siheung-gun. While working with the Korean Language Society, he was imprisoned in 1942 for the Korean Language Society Incident, an incident in which the Japanese government suppressed the members of the Korean Language Society through torture and imprisonment, and he also recalled the experience of being tortured. After liberation, he worked as a professor at Seoul National University, wrote Korean linguistics, and compiled a Korean dictionary.
In particular, Lee Hee-seung's Korean grammatical system, together with Choi Hyeon-bae's grammatical system, formed an important basis for the description of Korean linguistic grammar. Additionally, his 《Korean Language Dictionary, (257,854 words) published in 1961, is considered a great achievement of the Korean language .
For 20 years from 1968, he contributed to the honoring of Dangun as the chairman of the, and as the chairman of the Korean Language Education Research Association for 19 years from 1969, while striving for the right direction and correction of language education, he was inaugurated as the director of the Institute of Oriental Studies at Dankook University, compiled a dictionary of Korean and Korean history, and served as chairman of the Hyeonjeonghoe and advisor to the Liberation Society.
Born the eldest son of Lee Jong-shik in Poil-ri, Uigok-myeon (now Uiwang-si), Gwangju-gun, Gyeonggi-do, Hee-seung Lee spent his childhood in Gaepung-gun, Gyeonggi-do and Siheung-gun, Gyeonggi-do. From 1903 to 1908, he studied Chinese literature at a private school.
In 1908, the year he turned 13, he married Lee Jeong-ok of the Lee family in Gyeongju, and moved to Seoul, entering the English Department of the Hanseong Foreign Language School.
He then studied at Gyeongseong High School (now Gyeonggi High School) until September 1911, but he dropped out of Gyeongseong High School in protest of the Japanese compulsion and majored in law at Yangjeonguisuk (養正義塾) from 1912 to 1913.
In 1914, he became a teacher at the private Sinpung School, but Lee Hee-seung continued his education at the private Jung-dong School in the evening in 1915, and then graduated from the 4th year of the private central school in 1918.
In the same year, he started working as a clerk at Gyeongseong Textile Co., Ltd.[2]
In 1923, he passed the entrance exam for a vocational school again, graduated from Yonhee College in 1925, and then in 1927, he completed the preparatory course at Keijō Imperial University and graduated.
In the same year, he joined the Korean Language Society and served as secretary (director) and secretary general (representative secretary), and the 'Korean Spelling Unification Plan' (completed in 1933) and 'Standard Language Assessment' (completed in 1937) were promoted by the society.[2]
For 20 years from 1968, he contributed to the honoring of Dangun as the chairman of the, and for 19 years from 1969, as the chairman of the Korean Language Education Research Association, he participated in the correction of language education, such as advocating the mixed use of Korean and Korean texts.
In February 1955, he participated as one of the founders of the Inchon Kim Seong-soo Memorial Association. From 1971 to 1981, while serving as the director of the Institute of Oriental Studies affiliated with Dankook University, he contributed to the development of Korean Studies and Oriental Studies, by, for example, compiling a Korean-Korean Dictionary (recorded as the world's largest Chinese character dictionary).
Lee Hee-seung, who lived as a saennim (scholar) in Namsangol, said in his essay, 'Clicker', "Winter is here, so there is no way there will be firewood. The whole body straightens so that the legs and arms make a crackling sound, the limbs crouch down as they should, and the words that he says while grinding his teeth clenched hard as he struggles, “You bastard, you seem like such a disgusting cold, so you’re like this now. Don't rush, let's see next spring somewhere."
With his scholarly spirit, after the 5/16 military coup, he refused military rule when he was president of the Dong-A Ilbo, and under the Yushin constitution, he resolutely stood up against dictatorship as an advisor to the National Assembly for the Restoration of Democracy: "I was able to take pride in my life that I had walked the right path as others acknowledged."[3]
He died on November 27, 1989, at the age of 94, and is buried in Seonyeong, Munbong-ri, Byeokje-myeon, Goyang-gun, Gyeonggi-do (now Munbong-dong, Ilsandong-gu, Goyang-si).
《Joseon Linguistics Review》(published in 1947), selected and included only 16 of the 20 or so papers published from 1930 to 1940. The Introduction to Korean Linguistics is regarded as a masterpiece that presented the direction of Korean linguistics research in Korea. However, Lee Hee-seung's theory on grammar is dominated by Choi Hyun-bae 's grammar, and the data that appeared in a large amount of grammar theory lecture materials at universities are not available for public use.
A Study on Korean Grammar: The conjugation endings of verbs were not recognized as independent parts of speech, but various acrostic endings combined with verbs were recognized as an independent unit and called 'postpositions', and the linguistic form in which postpositions were combined with verbs was 'words' (語).節)', and the unit of parts of speech is a word, and the unit of writing is a word.
Parts of speech are nouns, pronouns, verbs, adjectives, beings, adjectives, adverbs, exclamations, conjunctions, and postpositional expressions, and the designating pronoun 'is' was treated as a predicate case particle, which is the use of the body language.
This grammatical system of Lee Hee-seung, along with Choi Hyun-bae's grammatical system, formed two major series of linguistic grammatical systems in Korea. In addition to grammatical theory, he paid great attention to words and vocabulary, and his 《Korean Language Dictionary》 (257,854 words, published in 1961) is considered a great achievement of the Korean language.
As a textbook, Elementary Korean Grammar (; 1949) and New Higher Grammar (; 1957), which supplemented it, were published.[4] The area of grammar was presented in three parts: general discourse, parts of speech, and writing. In In our language (; 1937) by Choi Hyeon-bae, the areas of grammar were Sorigal (音聲學), Ssigall (詞論), and (Writing) Wolgal (文章).
After graduating from the Department of Korean Language and Literature at Gyeongseong Imperial University, Ilseok, who taught at Ewha Women's Jeon, was arrested in 1942 for the Joseon Language Society Incident and served three years in prison until Japan was defeated.
After liberation, he became a professor at Seoul National University's Munri University, and together with Choi Hyeon-bae (at Yonsei University), they became the major scholars of Korean language.
Ilseok established the theoretical basis for the unification of orthography, established a Korean grammar system, and compiled a dictionary of the Korean language.
Ilseok left behind collections of essays Dumb cold heart, Blind man's sleep talking, Meddling in the words of an eating chu, and the poetry collections Park Flower and Fragments of the Heart .
His will made provision for the Ilseok Korean Linguistics Award (awarded since 2003), and in 2002, a 6-story Ilseok Academic Foundation building was erected on the site of Ilseok’s home in Dongsung-dong, Jongno-gu, Seoul.[5]
