|iso15924=Copt }} The Coptic alphabet is the script used for writing the Coptic language. The repertoire of glyphs is based on the Greek alphabet augmented by letters borrowed from the Egyptian Demotic and is the first alphabetic script used for the Egyptian language. There are several Coptic alphabets, as the Coptic writing system may vary greatly among the various dialects and subdialects of the Coptic language. ==History== The Coptic alphabet has a long history, going back to the Hellenistic period, of using the Greek alphabet to transcribe Demotic texts, with the aim of recording the correct pronunciation of Demotic. During the first two centuries of the Common Era, an entire series of magical texts were written in what scholars term ''Old Coptic'', Egyptian language texts written in the Greek alphabet. A number of letters, however, were derived from Demotic, and many of these (though not all) are used in "true" Coptic writing. With the spread of Christianity in Egypt, by the late 3rd century, knowledge of hieroglyphic writing was lost, as well as Demotic slightly later, making way for a writing system more closely associated with the Christian church. By the 4th century, the Coptic alphabet was "standardised", particularly for the Sahidic dialect. (There are a number of differences between the alphabets as used in the various dialects in Coptic.) Coptic is not generally used today except by the members of the Coptic Orthodox Church of Alexandria to write their religious texts. All the Gnostic codices found in Nag Hammadi used the Coptic alphabet. The Old Nubian alphabet—used to write Old Nubian, a Nilo-Saharan language —is written mainly in an uncial Greek alphabet, which borrows Coptic and Meroitic letters of Demotic origin into its inventory. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coptic alphabet」の詳細全文を読む スポンサード リンク
