Etymology 1 [ edit ]
The traditional account
holds that its form is the outline of an  incisor, 齒形 (it is the shape of the four teeth in the Chinese pictographic character for incisor, 齒).
Gari Ledyard proposes that ( ㅅ s) was derived from ( ㅈ j) by removing the top stroke.
ㅅ • ( s)
( 시옷 siot, “siot”), a jamo (letter) of the alphabet of the Korean writing system, hangeul; the sibilant phoneme ( /s/)
Usage notes [ edit ]
In the North Korean order,
( ㅅ s) is the seventh jamo, and in the South Korean order the tenth.
