Hangul syllable Tung

퉁 is a Korean syllable, roughly “toong” with the final nasal in “sing”; alone, it has no fixed meaning. Full words provide context: 퉁소 names a traditional vertical bamboo flute, while 퉁퉁하다 describes a broad or swollen body. Hangul was developed under King Sejong, ruler of Korea’s Joseon dynasty, for writing Korean; its creation is recorded in 1443, and a guide appeared in 1446.
