An abugida – sometimes also called alphasyllabary, neosyllabary, or pseudo-alphabet – is a segmental writing system in which consonant–vowel sequences are written as units; each unit is based on a consonant letter, and vowel notation is secondary, similar to a diacritical mark. This contrasts with a full alphabet, in which vowels have status equal to consonants, and with an abjad, in which vowel marking is absent, partial, or optional – in less formal contexts, all three types of the script may be termed "alphabets". The terms also contrast them with a syllabary, in which a single symbol denotes the combination of one consonant and one vowel.
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.
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 Thai script is the abugida used to write Thai, Southern Thai and many other languages spoken in Thailand. The Thai script itself has 44 consonant symbols, 16 vowel symbols that combine into at least 32 vowel forms, four tone diacritics, and other diacritics.
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.
When used as a diacritic mark, the term dot refers to the glyphs "combining dot above", and "combining dot below" which may be combined with some letters of the extended Latin alphabets in use in a variety of languages. Similar marks are used with other scripts.
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'.
The Turkmen alphabet refers to variants of the Latin alphabet, Cyrillic alphabet, or Arabic alphabet used for writing of the Turkmen language.
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'.
Rohingya is an Indo-Aryan language spoken by the Rohingya people of Rakhine State, Myanmar. It is an Eastern Indo-Aryan language belonging to the Bengali–Assamese branch, and is closely related to the Chittagonian language spoken in neighbouring Bangladesh. The Rohingya and Chittagonian languages have a high degree of mutual intelligibility.
Xiao'erjing, often shortened to Xiaojing, is a Perso-Arabic script used to write Sinitic languages, including Lanyin Mandarin, Zhongyuan Mandarin, Northeastern Mandarin, and Dungan. It is used on occasion by many ethnic minorities who adhere to Islam in China—mostly the Hui, but also the Dongxiang and the Salar—and formerly by their Dungan descendants in Central Asia. Orthographic reforms introduced the Latin script and later the Cyrillic script to the Dungan language, which continue to be used today.
In the context of the recitation of the Quran, tajwīd is a set of rules for the correct pronunciation of the letters with all their qualities and applying the various traditional methods of recitation (Qira'at). In Arabic, the term tajwīd is derived from the verb جود, meaning enhancement or to make something excellent. Technically, it means giving every letter its right in reciting the Qur'an.
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.
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.
Berber orthography is the writing system(s) used to transcribe the Berber languages.
Cyrillization of Arabic is the conversion of text written in Arabic script into Cyrillic script. Because the Arabic script is an abjad, an accurate transliteration into Cyrillic, an alphabet, would still require prior knowledge of the subject language to read. Instead, systems of transcription have normally been used.
The Hanifi Rohingya script is a unified script for the Rohingya language. Rohingya today is written in three scripts, Hanifi, Arabic, and Latin (Rohingyalish). The Rohingya language 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.
Kohistani Shina is an Indo-Aryan language spoken in the former Kohistan District of Khyber Pakhtunkhwa, northern Pakistan. According to Ethnologue, Kohistani Shina is mutually intelligible with the Shina variety of Chilas, but not with the standard dialect of Gilgit. Bateri and Kalkoti speakers speak Kohistani Shina as a second language. Indus Kohistani loanwords can be found in the language. A grammar and a dictionary of the language have been published.
The Swahili Ajami script refers to the alphabet derived from the Arabic script that is used for the writing of the Swahili language.
