Sha (Ш ш; italics: Ш ш) is a letter of the Glagolitic and Cyrillic script. It commonly represents the voiceless postalveolar fricative /ʃ/. More precisely, the sound in Russian denoted by ш is commonly transcribed as a palatoalveolar fricative but is actually a voiceless retroflex fricative. 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, Serbian, Macedonian, Croatian, Latvian and Lithuanian.

History[edit]

Sha has its earliest origins in Phoenician Shin and is linked closely to Shin's Greek equivalent: Sigma (Σ, σ, ς). (The similar form of the modern Hebrew Shin (ש), which is probably the origin of this letter[contradictory], derives 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 is the same as the Greek alphabet but with a few letters added at the end, including one called "shai" (Ϣϣ) which somewhat resembles both sha and shcha (Щ, щ) in appearance.

Use in mathematics[edit]

The Cyrillic letter Ш is internationally used in mathematics for several concepts:

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 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.
