The story
- Korean · derived from서울
- French · borrowed fromSéoul
- English todaySeoul
From French Séoul, from Korean 서울 (Seoul, literally “capital city”), originally from Claude-Charles Dallet's French-based romanization of Korean, reinforced by the 1959 South Korean Ministry of Education romanization of Korean, which transcribed the Korean vowel ㅓ (/ʌ/) with the digraph "eo" and which was official until 1984. Note that English Seoul predates the Revised Romanization romanization of Seoul. The two romanization systems simply produce identical forms.
