Also known as yeorinhieut
Yeorinhieut (letter: ; name: ) is an archaic consonant letter of the Korean alphabet, Hangul. In Unicode, its name is spelled yeorinhieuh, following the ISO/TR 11941 romanization system. It was historically widely called doenieung (), but the South Korean National Institute of Korean Language decided in 1991 to officially name it yeorinhieut because it was felt that contemporary South Koreans would more visually associate the graph with hieut over ieung. It was associated with a glottal stop .
