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.
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.
The Hebrew alphabet, known variously by scholars as the Ktav Ashuri, Jewish script, square script and block script, is traditionally an abjad script used in the writing of the Hebrew language and other Jewish languages, most notably Yiddish, Ladino, Judeo-Arabic, and Judeo-Persian. In modern Hebrew, vowels are increasingly introduced. It is also used informally in Israel to write Levantine Arabic, especially among Druze. It is an offshoot of the Imperial Aramaic alphabet, which flourished during the Achaemenid Empire and which itself derives from the Phoenician alphabet.
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.
Malayalam script is a Brahmic script used commonly to write Malayalam, which is the principal language of Kerala, India, spoken by 45 million people in the world. It is a Dravidian language spoken in the Indian state of Kerala and the union territories of Lakshadweep and Puducherry by the Malayali people. It is one of the official scripts of the Indian Republic. Malayalam script is also widely used for writing Sanskrit texts in Kerala.
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.
In writing and typography, a ligature occurs where two or more graphemes or letters are joined to form a single glyph. Examples are the characters ⟨æ⟩ and ⟨œ⟩ used in English and French, in which the letters ⟨a⟩ and ⟨e⟩ are joined for the first ligature and the letters ⟨o⟩ and ⟨e⟩ are joined for the second ligature. For stylistic and legibility reasons, ⟨f⟩ and ⟨i⟩ are often merged to create ⟨fi⟩ ; the same is true of ⟨s⟩ and ⟨t⟩ to create ⟨st⟩. The common ampersand, ⟨&⟩, developed from a ligature in which the handwritten Latin letters ⟨e⟩ and ⟨t⟩ were combined.
The Tamil script is an abugida script that is used by Tamils and Tamil speakers in India, Sri Lanka, Malaysia, Singapore, Indonesia and elsewhere to write the Tamil language. It is one of the official scripts of the Indian Republic. Certain minority languages such as Saurashtra, Badaga, Irula and Paniya are also written in the Tamil script.
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'.
Waw is the sixth letter of the Semitic abjads, including Phoenician wāw 𐤅, Aramaic waw 𐡅, Hebrew vavו, Syriac waw ܘ and Arabic wāwو.
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.
Rasm is an Arabic writing script often used in the early centuries of Classical Arabic literature. Essentially it is the same as today's Arabic script except for the big difference that the Arabic diacritics are omitted. These diacritics include i'jam, consonant pointing, and tashkil, supplementary diacritics. The latter include the ḥarakāt (حَرَكَات) short vowel marks—singular: ḥarakah (حَرَكَة). As an example, in rasm, the two distinct letters ص ض are indistinguishable because all the dots are omitted. Rasm is also known as Arabic skeleton script.
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 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 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.
Many scripts in Unicode, such as Arabic, have special orthographic rules that require certain combinations of letterforms to be combined into special ligature forms. In English, the common ampersand (&) developed from a ligature in which the handwritten Latin letters e and t were combined. The rules governing ligature formation in Arabic can be quite complex, requiring special script-shaping technologies such as the Arabic Calligraphic Engine by Thomas Milo's DecoType.
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.
There are three writing systems for Saraiki:
Cham Jawi is a variant of the Jawi adaptation of the Arabic script used to write the Cham language.
