Ꞩ, ꞩ, ẜ (S with oblique stroke) is an extended Latin letter that was used in Latvian orthography until 1921; ꞩ was also used in Lower Sorbian until 1950.^[1] A variant of the letter S with a stroke, encoded at U+A7CC Ꟍ LATIN CAPITAL LETTER S WITH DIAGONAL STROKE and U+A7CD ꟍ LATIN SMALL LETTER S WITH DIAGONAL STROKE, is used in Luiseño^[2] and Cupeño,^[3] and has been encoded since Unicode 16.0.

Uses in alphabets

In Latvian orthography until 1921 it meant the sound IPA: [s] (while the S s meant the sound IPA: [z]). It was also used in the trigraph Ꞩch ẜch and the tetragraph Tẜch tẜch, denoted by the sounds IPA: [ʃ] and IPA: [t͡ʃ], respectively. Spelling reform Ꞩ ẜ ꞩ, Ꞩch ẜch, Tẜch tẜch were replaced by S s, Š š, Č č respectively.^[4]

In the final version of the Unified Northern Alphabet, created in the USSR in the 1930s for the languages of the peoples of Siberia and the Far North, for the Selkup, Khanty and Mansi languages, it meant the sound IPA: [ʃ].^[5]
