The purpose of the study is to analyze the linguistic characteristics in North Korean middle school Korean language arts(KLA) textbooks and to explore their educational meaning. I acquired North Korean KLA textbooks from the Information Center on North Korea, converted it to text corpus(hwp file) using Hangul program, and converted it to text file on computer. As a result of analysis of ’North Korean KLA textbooks corpus’ using AntConc3.2.4w, I found the following in formation. (1) One of the most frequent and meaningful words is “kyeong- ae-ha-neun”(literally meaning venerable). (2) Concordance analysis of “kyeong-ae-ha-neun” shows that the word appears only before North Korean head of state. (3) Collocation analysis of “kyeong-ae-ha-neun” shows that the occurrence of two or more words such as “kyeong-ae-ha-neun”+“a term referring to thr North Korean head of state” in declarative manner. The so-called “kyeong-ae-ha-neun” phenomenon in North Korean textbooks is a means to impose the significance of North Korean head of state and the impression of him on North Korean students.
