The Arabic alphabet, or the Arabic abjad, is the Arabic script as specifically codified for writing the Arabic language. It is written from right-to-left in a cursive style, and includes 28 letters, of which most have contextual letterforms. Unlike the Latin alphabet, the script has no concept of letter case. The Arabic alphabet is considered an abjad, with only consonants required to be written; due to its optional use of diacritics to notate vowels, it is considered an impure abjad.
A diacritic is a glyph added to a letter or to a basic glyph. The term derives from the Ancient Greek διακριτικός, from διακρίνω. The word diacritic is a noun, though it is sometimes used in an attributive sense, whereas diacritical is only an adjective. Some diacritics, such as the acute ⟨ó⟩, grave ⟨ò⟩, and circumflex ⟨ô⟩, are often called accents. Diacritics may appear above or below a letter or in some other position such as within the letter or between two letters.
A mater lectionis is any consonant that is used to indicate a vowel, primarily in the writing of Semitic languages such as Arabic, Hebrew and Syriac. The letters that do this in Hebrew are aleph א, he ה, waw ו and yod י, with the latter two in particular being more often vowels than they are consonants. In Arabic, the matres lectionis are ʾalif ا, wāw و and yāʾ ي.
Thaana, Tãnaa, Taana or Tāna is the present writing system of the Maldivian language spoken in the Maldives. Thaana has characteristics of both an abugida and a true alphabet, with consonants derived from indigenous and Arabic numerals, and vowels derived from the vowel diacritics of the Arabic abjad. Maldivian orthography in Thaana is largely phonemic.
The Arabic script has numerous diacritics, which include consonant pointing known as iʻjām (إِعْجَام), and supplementary diacritics known as tashkīl (تَشْكِيل). The latter include the vowel marks termed ḥarakāt.
The Azerbaijani alphabet has three versions which includes the Arabic, Latin, and Cyrillic alphabets.
Wakhi is an Indo-European language in the Eastern Iranian branch of the language family spoken today in Wakhan District, Northern Afghanistan, and neighboring areas of Tajikistan, Pakistan and China.
Aljamiado or Aljamía texts are manuscripts that use the Arabic script for transcribing European languages, especially Romance languages such as Old Spanish or Aragonese. This alphabet is also called the Morisco alphabet.
Shaddah is one of the diacritics used with the Arabic alphabet, indicating a geminated consonant. It is functionally equivalent to writing a consonant twice in the orthographies of languages like Latin, Italian, Swedish, and Ancient Greek, and is thus rendered in Latin script in most schemes of Arabic transliteration, e.g. رُمّان = rummān 'pomegranates'.
Sorabe or Sora-be is an abjad based on Arabic, formerly used to transcribe the Malagasy language and the Antemoro Malagasy dialect, dating from the 15th century.
The Ottoman Turkish alphabet is a version of the Perso-Arabic script used to write Ottoman Turkish until 1928, when it was replaced by the Latin-based modern Turkish alphabet.
The Urdu alphabet is the right-to-left alphabet used for writing Urdu. It is a modification of the Persian alphabet, which itself is derived from the Arabic script. It has co-official status in India, Pakistan, and South Africa. The Urdu alphabet has up to 39 or 40 distinct letters with no distinct letter cases and is typically written in the calligraphic Nastaʿlīq script, whereas Arabic is more commonly written in the Naskh style.
Wolofal is a derivation of the Arabic script for writing the Wolof language. It is basically the name of a West African Ajami script as used for that language.
The hamza is an Arabic script character that, in the Arabic alphabet, denotes a glottal stop and, in non-Arabic languages, indicates a diphthong, vowel, or other features, depending on the language. Derived from the letter ʿAyn, the hamza is written in initial, medial and final positions as an unlinked letter or placed above or under a carrier character. Despite its common usage as a letter in Modern Standard Arabic, it is generally not considered to be one of its letters, although some argue that it should be considered a letter.
The Pashto alphabet is the right-to-left abjad-based alphabet developed from the Arabic script, used for the Pashto language in Pakistan and Afghanistan. It originated in the 16th century through the works of Pir Roshan.
Pegon is a modified Arabic script used to write the Javanese, Sundanese, and Madurese languages, as an alternative to the Latin script or the Javanese script and the Old Sundanese script. It was used in a variety of applications, from religion, to diplomacy, to poetry. But today particularly, it is used for religious (Islamic) writing and poetry, particularly in writing commentaries of the Qur'an. Pegon includes letters that are not present in Modern Standard Arabic. Pegon has been studied far less than its Jawi counterpart which is used for Malay, Acehnese and Minangkabau.
The Khowar alphabet is the right-to-left alphabet used for the Khowar language. It is a modification of the Urdu alphabet, which is itself a derivative of the Persian alphabet and Arabic alphabet and uses the calligraphic Nastaʿlīq script.
The Swahili Ajami script refers to the alphabet derived from the Arabic script that is used for the writing of the Swahili language.
The Rohingya Arabic Alphabet is a modified Arabic script for the Rohingya language. Rohingya today is written in three scripts, Hanifi Rohingya script, Arabic Alphabet, and Latin (Rohingyalish). Rohingya was first written in the 19th century with a version of the Perso-Arabic script. In 1975, an orthographic Arabic script was developed and approved by the community leaders, based on the Urdu alphabet but with unique innovations to make the script suitable to Rohingya.
Cham Jawi is a variant of the Jawi adaptation of the Arabic script used to write the Cham language.
