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 modern 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.
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 Persian alphabet, also known as the Perso-Arabic script, is the right-to-left alphabet used for the Persian language. It is a variation of the Arabic script with five additional letters: پ چ ژ گ, in addition to the obsolete ڤ that was used for the sound. This letter is no longer used in Persian, as the -sound changed to, e.g. archaic زڤان > زبان 'language'.
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.
Aleph is the first letter of the Semitic abjads, including Phoenician ʾālep 𐤀, Hebrew ʾālefא, Aramaic ʾālap 𐡀, Syriac ʾālap̄ ܐ, Arabic ʾalifا, and North Arabian 𐪑. It also appears as South Arabian 𐩱 and Ge'ez ʾälef አ.
The romanization of Arabic is the systematic rendering of written and spoken Arabic in the Latin script. Romanized Arabic is used for various purposes, among them transcription of names and titles, cataloging Arabic language works, language education when used instead of or alongside the Arabic script, and representation of the language in scientific publications by linguists. These formal systems, which often make use of diacritics and non-standard Latin characters are used in academic settings for the benefit of non-speakers, contrast with informal means of written communication used by speakers such as the Latin-based Arabic chat alphabet.
Nunation, in some Semitic languages such as Literary Arabic, is the addition of one of three vowel diacritics (ḥarakāt) to a noun or adjective.
Arwi or Arabu-Tamil is an Arabic-influenced dialect of the Tamil language written with an extension of the Arabic alphabet, with extensive lexical and phonetic influences from the Arabic language. Arwi has been used extensively by the Muslims of the Tamil Nadu state of India and Sri Lanka.
Serer, often broken into differing regional dialects such as Serer-Sine and Serer saloum, is a language of the Senegambian branch of the Niger–Congo family spoken by 1.2 million people in Senegal and 30,000 in the Gambia as of 2009. It is the principal language of the Serer people, and was the language of the early modern kingdoms of Sine, Saloum, and Baol.
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 the republics of Pakistan, India 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 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.
There are three writing systems for Saraiki:
Sindhi is a language broadly spoken by the people of the historical Sindh region in the Indian subcontinent. Modern Sindhi is written in an extended Perso-Arabic script in Sindh province of Pakistan and (formally) in extended-Devanagari by Sindhis in partitioned India. Historically, Sindhi was written in various forms of Landa scripts and various other Indic scripts.
The Swahili Ajami script refers to the alphabet derived from the Arabic script that is used for the writing of the Swahili language.
Cham Jawi is a variant of the Jawi adaptation of the Arabic script used to write the Cham language, mainly Western Cham. This variation of writing was developed at the beginning of the arrival of Islam in Champa around the 14th to 15th centuries, mainly due to the influence of the Sultanate of Malacca on the Malay Peninsula.
