So far, there have been three types of ways to utilize research results in lexical history in Korean language education. The first is to use it for vocabulary education, the second is for teaching Korean language history, and the third is to use it in all areas of grammar, including morphology, syntax, semantics, and phonology. In relation to the method of using the research results of lexical history for vocabulary education, there were overwhelmingly many studies focusing on enhancing understanding of culture rather than vocabulary education. This paper introduced activities to classify vocabulary types using lexical history, to find out the meaning and meaning relationship of words, to correct incorrect information on foreign words, and examined ways to educate various areas of grammar centered on lexical history.
