Daeseong

Daeseong (Korean: 대성; Hanja: 大成) is a Korean term that appears in personal names and place names. The Sino-Korean characters 大 meaning “great” and 成 meaning “to accomplish” convey the idea of great achievement or success. The combination is common in naming and toponymy in Korea, where meanings vary with the hanja chosen.

As a given name, Daeseong is typically masculine. In Korean naming practice, the exact meaning depends on the hanja used for each syllable. When written as 大成, the name broadly suggests aspirations toward greatness and accomplishment. Because many hanja combinations can read as Daeseong, the precise interpretation and rarity of the name depend on the characters selected by the family.

In geography, Daeseong appears in several Korean place names, often in the form Daeseong-dong (a neighborhood) or Daeseong-myeon (a township) or as part of another locality name. Such use reflects historical or aspirational associations with greatness or prosperity in the area’s naming history.

Daeseong also occurs in cultural and commercial contexts as a component in school, corporate, or religious names, again drawing on the positive connotations of greatness. The pronunciation can be rendered in various romanizations, including Daeseong, Dae-seong, or Daesung. The spelling Daesung is also used as a stage name in popular culture, notably by a member of the South Korean group Big Bang.
