Names of Seoul

An early 20th century trading card from Germany, using an alternate spelling of Seoul, with "ö" for "eo".

Seoul has been known in the past by the successive names Wiryeseong (Korean위례성; Hanja慰禮城, Baekje era), Namgyeong (남경; 南京, Goryeo era), Hanseong (한성; 漢城, Joseon era) or Hanyang (한양; 漢陽). During the period of Japanese occupation (1910–1945), Seoul was named to the Japanese Keijō (けいじょう or 京城) or Gyeongseong (경성; 京城) in Korean. Its current name is Seoul, and this name has been in use since at least 1882, at times concurrently with other names.[1]

Etymology of "Seoul"

Seoul is a rendering of the Korean word “seo'ul” (서울), pronounced [səˈul]. An etymological hypothesis presumes that the origin of the native word “seo'ul” derives from the native name Seorabeol (Korean서라벌; Hanja徐羅伐), which originally referred to Gyeongju, the capital of Silla, then called Geumseong (금성; 金城).
