North Korea shares the Korean language with South Korea, although some dialectal differences exist within both Koreas. North Koreans refer to their Pyongyang dialect as ''munhwaŏ'' ("cultured language") as opposed to the dialects of South Korea, especially the Seoul dialect or ''p'yojun'ŏ'' ("standard language"), which are viewed as decadent because of its use of loanwords from Chinese and European languages (particularly English). Words of Chinese, Manchu or Western origin have been eliminated from ''munhwa'' along with the usage of Chinese hancha characters. Written language uses only the chosŏn'gŭl (Hangul) phonetic alphabet, developed under Sejong the Great (1418–1450).
