Cyrillic digraphs

Sha (Ш ш; italics: Ш ш) is a letter of the Cyrillic script. It commonly represents the voiceless postalveolar fricative /ʃ/, like the pronunciation of ⟨sh⟩ in sheep, or the somewhat similar voiceless retroflex fricative /ʂ/. It is used in every variation of the Cyrillic alphabet, for Slavic and non-Slavic languages.^{[citation needed]}

In English, Sha is romanized as ⟨sh⟩ or as ⟨š⟩, the latter being the equivalent letter in the Latin alphabets of Czech, Slovak, Slovene, Croatian, Latvian and Lithuanian.

[edit] History

Sha has its earliest origins in Phoenician Shin and is linked closely to Shin's Greek equivalent: Sigma (Σ, σ, ς). (Note the similar form of the modern Hebrew Shin (ש), which is probably the origin of this letter, deriving from the same Proto-Canaanite source). Sha already possessed its current form in Saints Cyril and Methodius's Glagolitic alphabet. Most Cyrillic letter-forms were derived from the Greek, but as there was no Greek sign for the Sha sound (modern Greek uses simply Σ/σ/ς to spell the sh-sound in foreign words and names), Glagolitic Sha was adopted unchanged. There is a possibility that Sha was taken from the Coptic alphabet, which was the same as the Greek alphabet but had a few letters added at the end, including one called shai which somewhat resembles both sha and shcha (Щ, щ) in appearance.

[edit] Use in mathematics

Ш has the distinction of being the only^{[citation needed]} distinctly Cyrillic letter internationally used in mathematics:

In algebraic geometry, the Tate–Shafarevich group of an Abelian variety A over a field K is denoted Ш(A/K), a notation first suggested by J. W. S. Cassels. (Previously it had been unimaginatively denoted TS.)

In a different mathematical context, some authors allude to the shape of the letter Sha when they use the term Shah function for what is otherwise called a Dirac comb.

The shuffle product is often denoted by ш.
