释义 | Arabic alphabet ![]() The Arabic alphabet has 28 letters, all representing consonants, and is written from right to left. Twenty-two of the letters are those of the Semitic alphabet from which it descended, modified only in letter form, and the remaining six letters represent sounds not used in the languages written in the earlier alphabet. The shape of each letter depends on its position in a word—initial, medial, and final. There is a fourth form of the letter when it is written alone. The letters alif, waw, and ya (standing for glottal stop, w, and y, respectively) are used to represent the long vowels a, u, and i. A set of diacritical marks developed in the 8th century AD are sometimes used to represent short vowels and certain grammatical endings otherwise left unmarked. Two major types of Arabic script exist. Kūfic (Kūfic script), a thick, bold monumental style, was developed in Kūfah, a city in Mesopotamia, toward the end of the 7th century AD. It was used chiefly for inscriptions in stone and metal but was also employed sometimes to write manuscripts of the Qurʾān. A very handsome monumental script, it has passed out of use, except in cases in which more cursive scripts cannot be used. Naskhī, (naskhī script) a cursive script well adapted to writing on papyrus or paper, is the direct ancestor of modern Arabic writing. It originated in Mecca and Medina at an early date and exists in many complex and decorative variant forms. |
