The Pyong'an dialect (Korean: 평안도 사투리; MR: p'yŏngando sat'uri), alternatively Northwestern Korean (Korean: 서북 방언; Hanja: 西北方言; MR: sŏbuk pangŏn), is the Korean dialect of the Northwestern Korean peninsula and neighboring parts of China. It has influenced the standard Korean of North Korea, but is not the primary influence of North Korea's standard Korean (the Gyeonggi dialect, the Korean language standard of Joseon-era Korea for roughly 500 years, is the foundation of standard Korean in both North and South Korea).
