uuc=0428|ulc=0448Sha (Ш, ш, italics: "Ш, ш") is a letter of the
Cyrillic alphabet , representing the consonant sound IPA|/ʃ/ or IPA|/ʂ/. It is roughly equivalent to "sh" in English, "ch" in French, "sch" in German, "ش" in Arabic, "ש" in Hebrew, "ş" in Turkish, or "sz" in Polish. In most Latin-alphabet Slavic languages (Czech, Slovak, Serbian, Slovene, Croatian) this sound is written "š", and linguists have adopted this symbol to transliterate ш into the Latin alphabet.The printed Sha looks something like a
W or, more exactly, like anE rotated to the left 90 degrees. It is used in virtually every national variation of theCyrillic alphabet , for Slavic and non-Slavic languages. In mathematics, theTate-Shafarevich group is denoted Ш, a notation first suggested byJ. 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 aDirac comb .The sound IPA|/ʃ/ is described as a
voiceless postalveolar fricative . The postalveolar fricatives are the major reason why theGlagolitic and later the Cyrillic alphabet were invented, because they cannot be written with a simple Roman or Greek letter without diacritics or digraphs. Slavic languages are rich in postalveolar fricatives andaffricate s, and Sha is one of the most typical letters of the Cyrillic alphabet.Sha has its earliest origins in
Proto-Canaanite Shin and is linked closely to Shin's Greek equivalent: Sigma (Σ, σ). (Note the similar form of the modern Hebrew Shin (ש) which also derives from the same Proto-Canaanite source). Sha already possessed its current form in Saints Cyril and Methodius'sGlagolitic 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" to spell the sh-sound in foreign words and names), Glagolitic Sha was adopted unchanged. There is a possibility that Sha was taken from theCoptic 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 andshcha (Щ, щ) in appearance.ee also
