《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.
