An abugida, sometimes known as 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, like 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 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 ⟨á⟩, grave ⟨à⟩, and circumflex ⟨â⟩, 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.
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.
Baybayin is a Philippine script. The script is an abugida belonging to the family of the Brahmic scripts. Geographically, it was widely used in Luzon and other parts of the Philippines prior to and during the 16th and 17th centuries before being replaced by the Latin alphabet during the period of Spanish colonization. It was used in the Tagalog language and, to a lesser extent, Kapampangan-speaking areas; its use spread to the Ilocanos in the early 17th century. In the 19th and 20th centuries, baybayin survived and evolved into multiple forms—the Tagbanwa script of Palawan, and the Hanuno'o and Buhid scripts of Mindoro—and was used to create the constructed modern Kulitan script of the Kapampangan and the Ibalnan script of the Palawan people. Under the Unicode Standard and ISO 15924, the script is encoded as the Tagalog block.
The Batak script is a writing system used to write the Austronesian Batak languages spoken by several million people on the Indonesian island of Sumatra. The script may be derived from the Kawi and Pallava script, ultimately derived from the Brahmi script of India, or from the hypothetical Proto-Sumatran script influenced by Pallava.
Khmer script is an abugida (alphasyllabary) script used to write the Khmer language, the official language of Cambodia. It is also used to write Pali in the Buddhist liturgy of Cambodia and Thailand.
Surat Buhid is an abugida used to write the Buhid language. As a Brahmic script indigenous to the Philippines, it closely related to Baybayin and Hanunó'o. It is still used today by the Mangyans, found mainly on island of Mindoro, to write their language, Buhid, together with the Filipino latin script.
Tagbanwa is one of the scripts indigenous to the Philippines, used by the Tagbanwa and the Palawan people as their ethnic writing system.
Old Javanese is a supposedly Brahmic-based writing system traditionally used to write the Old Javanese, and was spread across Java and much of Maritime Southeast Asia between the 8th century and the 16th century. The script is an abugida meaning that characters are read with an inherent vowel. Diacritics are used, either to suppress the vowel and represent a pure consonant, or to represent other vowels.
Virama is a Sanskrit phonological concept to suppress the inherent vowel that otherwise occurs with every consonant letter, commonly used as a generic term for a codepoint in Unicode, representing either
- halanta, hasanta or explicit virāma, a diacritic in many Brahmic scripts, including the Devanagari and Bengali scripts, or
- saṃyuktākṣara or implicit virama, a conjunct consonant or ligature.
Mandombe or Mandombé is a script proposed in 1978 in Mbanza-Ngungu in the Bas-Congo province of the Democratic Republic of the Congo by Wabeladio Payi, who related that it was revealed to him in a dream by Simon Kimbangu, the prophet of the Kimbanguist Church. Mandombe is based on the sacred shapes and , and intended for writing African languages such as Kikongo, as well as the four national languages of the Congo, Kikongo ya leta, Lingala, Tshiluba and Swahili, though it does not have enough vowels to write Lingala fully. It is taught in Kimbanguist church schools in Angola, the Republic of the Congo, and the Democratic Republic of the Congo. It is also promoted by the Kimbanguist Centre de l’Écriture Négro-Africaine (CENA). The Mandombe Academy at CENA is currently working on transcribing other African languages in the script. It has been classified as the third most viable indigenous script of recent indigenous west African scripts, behind only the Vai syllabary and the N'Ko alphabet.
New Tai Lue script, also known as Xishuangbanna Dai and Simplified Tai Lue, is an abugida used to write the Tai Lü language. Developed in China in the 1950s, New Tai Lue is based on the traditional Tai Tham alphabet developed c. 1200. The government of China promoted the alphabet for use as a replacement for the older script; teaching the script was not mandatory, however, and as a result many are illiterate in New Tai Lue. In addition, communities in Burma, Laos, Thailand and Vietnam still use the Tai Tham alphabet.
The Lepcha script, or Róng script, is an abugida used by the Lepcha people to write the Lepcha language. Unusually for an abugida, syllable-final consonants are written as diacritics.
The Lontara script, also known as the Bugis script, Bugis-Makassar script, or Urupu Sulapa’ Eppa’ "four-cornered letters", is one of Indonesia's traditional scripts developed in the South Sulawesi and West Sulawesi region. The script is primarily used to write the Buginese language, followed by Makassarese and Mandar. Closely related variants of Lontara are also used to write several languages outside of Sulawesi such as Bima, Ende, and Sumbawa. The script was actively used by several South Sulawesi societies for day-to-day and literary texts from at least mid-15th Century CE until the mid-20th Century CE, before its function was gradually supplanted by the Latin alphabet. Today the script is taught in South Sulawesi Province as part of the local curriculum, but with very limited usage in everyday life.
Carrier or Déné syllabics is a script created by Adrien-Gabriel Morice for the Carrier language. It was inspired by Cree syllabics and is one of the writing systems in the Canadian Aboriginal syllabics Unicode range.
Pahawh Hmong is an indigenous semi-syllabic script, invented in 1959 by Shong Lue Yang, to write two Hmong languages, Hmong Daw (Hmoob Dawb White Miao) and Hmong Njua AKA Hmong Leng (Moob Leeg Green Miao).
The Bamum scripts are an evolutionary series of six scripts created for the Bamum language by Ibrahim Njoya, King of Bamum. They are notable for evolving from a pictographic system to a semi-syllabary in the space of fourteen years, from 1896 to 1910. Bamum type was cast in 1918, but the script fell into disuse around 1931. A project began around 2007 to revive the Bamum script.
Kulitan, also known as súlat Kapampángan and pamagkulit, is one of the various indigenous suyat writing systems in the Philippines. It was used for writing Kapampangan, a language mainly spoken in Central Luzon, until it was gradually replaced by the Latin alphabet.
Ambahan is a traditional form of poetry by the Hanunó'o Mangyan people of Mindoro, Philippines.
Suyat is the modern collective name of the indigenous scripts of various ethnolinguistic groups in the Philippines prior to Spanish colonization in the 16th century up to the independence era in the 21st century. The scripts are highly varied; nonetheless, the term was suggested and used by cultural organizations in the Philippines to denote a unified neutral terminology for Philippine indigenous scripts.
