New Korean Orthography

[1] The study of Russian was also made compulsory from middle school onward,[1] and communist terminology—such as Workers' Party, People's Army, and Fatherland Liberation War—were rapidly assimilated into Korean.

[2] The ban on Hanja in 1949 (excepting parenthetical references in scientific and technical publications) was part of a language purification movement which sought to replace Sino-Korean vocabulary and loanwords from Japanese with native neologisms on the grounds that they were "reactionary" and separated the literary intelligentsia from the masses.

[1] In March 1958, the new orthography's creator, Kim Tu Bong, was purged from the Party, and linguistics journals began publishing attacks on him and his system.

[3] In the 1960s, Kim Il Sung issued a directive that would bind all future language planning to Korean ethnic nationalism, saying that "people of the same racial make-up, the same culture, living in the same territory ... [have a] need for a nationalistic, pure standard".

[citation needed] The reason for the reform is that some Korean roots change form and therefore cannot be written with a consistent spelling using standard Hangul.

In New Orthography, the root is an invariable 거ᇫ, spelled with the new letter ㅿ in place of both the ㄷ in 걷 and the ㄹ in 걸: 거ᇫ다 kŏtta, 거ᇫ어 kŏrŏ.

The attributive ㄴ n morpheme at the ends of adjectives is also placed in a separate block, and the occasional epenthetic ŭ that appears before it is not written, unlike standard 은 ŭn.
