The research on sentence theory in South Korea has focused on ‘sentence analysis’ and has not been sufficiently discussed from the perspective of ‘sentence construction’. However, under the problem that grammar education contents from the functional grammar perspective of ‘sentence construction’ need to be organized in syntactic theory as well, this study attempts to reveal the characteristics of North Korean grammar education contents from the functional grammar perspective, centering on the functional sentence theory of Korean language in 『Functional Grammar of Joseon Language』 (2013). To this end, in Chapter 2, we reviewed previous discussions on North Korean grammar as a functional grammar, and in Chapter 3, we examined the functional sentence theory of Korean in 『Functional Grammar of Korean 』 (2013) to discuss its implications for grammar education in South Korea, which is based on ‘sentence analysis’. In doing so, we are expected to gain a deeper understanding of the characteristics of North Korean grammatical content from a functional grammar perspective at the syntactic level, and to provide implications for grammar education in South Korea, which is biased toward ‘sentence analysis’.
