Ƨ

Ƨ (minuscule: ƨ) is a letter which appears in numerous alphabets, including some proposed extensions of the Latin alphabet. Depending on the context in which the letter is used, it is typically based either on the numeral 2 or the Latin letter S.

Ƨ was used in the Zhuang alphabet from 1957 to 1986 to indicate the second, or falling, tone (IPA: [˧˩]), due to its resemblance to the numeral 2, along with four other letters resembling numbers. (See: Table). In 1986, Ƨ was replaced by the similarly shaped, but fully Latin Z, when the alphabet was simplified for use in computers.

The proposed Metelko alphabet, devised by Franc Serafin Metelko, used the letter Ƨ to represent the schwa ə sound; it is unclear what inspiration Metelko used for the character (possibly from the Georgian letter ჷ used in the Laz and Svan languages spoken in the Southern Caucasus).

A similar sign, 𐆓, was used as a fractional Roman numeral, standing for the fraction 1⁄72.

In italic type, ⟨г⟩ Cyrillic's ge ⟨г⟩ is strongly homoglyphic to the lowercase ƨ. Early forms of the letter dze ⟨S⟩, currently only used in Macedonian Cyrillic, could resemble either a forward or reversed S. The Old Novgorodian birchbark documents have exclusively a reversed version of the letter.

Reversed S is very often used in languages using the Latin alphabet as a substitute for S, to depict a young child's handwriting.
