Doubled ㅅ (siot)
ㅆ • (ss)
- A digraph of Hangul, the Korean alphabet.
- In North Korea, ㅆ is called 된시읏 (doensieut), "strong ㅅ (sieut)". In South Korea, it is called 쌍시옷 (ssangsiot), "doubled ㅅ (siot)".
- ㅆ is pronounced as a sibilant with tense phonation (IPA: [s͈] or [z̬]), i.e. similar to the English s, but with a stiff tongue and glottal opening.
In Dongguk Jeongun(東國正韻), this letter was used to transcribe voiced alveolar fricative(/z/) of Middle Chinese.
