Seong-won (also spelled Sung-won) is a Korean unisex given name. Its meaning derives from Sino-Korean characters: it commonly combines 成 (seong) meaning "completed, finished, succeeded" with 元 (won) meaning "first, origin" or 源 (won) meaning "source, origin". However, as is common in Korean naming practice, other hanja combinations with similar sounds may also be used to form this name. Etymology and Cultural Context The first element seong (성) is a common element in Korean names, often signifying achievement. The second element won (원) frequently appears in names, suggesting beginnings or origins. The combination embodies a positive wish for success and leadership.
