An alphabet is a standard set of letters written to represent particular sounds in a spoken language. Specifically, letters correspond to phonemes, the categories of sounds that can distinguish one word from another in a given language. Not all writing systems represent language in this way: a syllabary assigns symbols to spoken syllables, while logographies assign symbols to words, morphemes, or other semantic units.
An abjad, also abgad, is a writing system in which only consonants are represented, leaving vowel sounds to be inferred by the reader. This contrasts with alphabets, which provide graphemes for both consonants and vowels. The term was introduced in 1990 by Peter T. Daniels. Other terms for the same concept include partial phonemic script, segmentally linear defective phonographic script, consonantary, consonant writing, and consonantal alphabet.
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.
In the linguistic study of written languages, a syllabary is a set of written symbols that represent the syllables or moras which make up words.
The Sinhala script, also known as Sinhalese script, is a writing system used by the Sinhalese people and most Sri Lankans in Sri Lanka and elsewhere to write the Sinhala language as well as the liturgical languages Pali and Sanskrit. The Sinhalese Akṣara Mālāva, one of the Brahmic scripts, is a descendant of the Ancient Indian Brahmi script. It is also related to the Grantha script.
Egyptian hieroglyphs were the formal writing system used in Ancient Egypt for writing the Egyptian language. Hieroglyphs combined logographic, syllabic and alphabetic elements, with more than 100 distinct characters. Cursive hieroglyphs were used for religious literature on papyrus and wood. The later hieratic and demotic Egyptian scripts were derived from hieroglyphic writing, as was the Proto-Sinaitic script that later evolved into the Phoenician alphabet. Through the Phoenician alphabet's major child systems, the Egyptian hieroglyphic script is ancestral to the majority of scripts in modern use, most prominently the Latin and Cyrillic scripts and the Arabic script, and possibly the Brahmic family of scripts.
In a written language, a logogram, also logograph or lexigraph, is a written character that represents a semantic component of a language, such as a word or morpheme. Chinese characters as used in Chinese as well as other languages are logograms, as are Egyptian hieroglyphs and characters in cuneiform script. A writing system that primarily uses logograms is called a logography. Non-logographic writing systems, such as alphabets and syllabaries, are phonemic: their individual symbols represent sounds directly and lack any inherent meaning. However, all known logographies have some phonetic component, generally based on the rebus principle, and the addition of a phonetic component to pure ideographs is considered to be a key innovation in enabling the writing system to adequately encode human language.
Shorthand is an abbreviated symbolic writing method that increases speed and brevity of writing as compared to longhand, a more common method of writing a language. The process of writing in shorthand is called stenography, from the Greek stenos (narrow) and graphein. It has also been called brachygraphy, from Greek brachys (short), and tachygraphy, from Greek tachys, depending on whether compression or speed of writing is the goal.
Canadian syllabic writing, or simply syllabics, is a family of writing systems used in a number of Indigenous Canadian languages of the Algonquian, Inuit, and (formerly) Athabaskan language families. These languages had no formal writing system previously. They are valued for their distinctiveness from the Latin script and for the ease with which literacy can be achieved. For instance, by the late 19th century the Cree had achieved what may have been one of the highest rates of literacy in the world.
The Meroitic script consists of two alphasyllabic scripts developed to write the Meroitic language at the beginning of the Meroitic Period of the Kingdom of Kush. The two scripts are Meroitic Cursive, derived from Demotic Egyptian, and Meroitic Hieroglyphs, derived from Egyptian hieroglyphs. Meroitic Cursive is the most widely attested script, comprising ~90% of all inscriptions, and antedates, by a century or more, the earliest, surviving Meroitic hieroglyphic inscription. Greek historian Diodorus Siculus described the two scripts in his Bibliotheca historica, Book III (Africa), Chapter 4. The last known Meroitic inscription is the Meroitic Cursive inscription of the Blemmye king, Kharamadoye, from a column in the Temple of Kalabsha, which has recently been re-dated to AD 410/ 450 of the 5th century. Before the Meroitic Period, Egyptian hieroglyphs were used to write Kushite names and lexical items.
The Yi scripts are two scripts used to write the Yi languages; Classical Yi, and the later Yi syllabary. The script is historically known in Chinese as Cuan Wen or Wei Shu and various other names (夷字、倮語、倮倮文、畢摩文), among them "tadpole writing" (蝌蚪文).
Japanese Braille is the braille script of the Japanese language. It is based on the original braille script, though the connection is tenuous. In Japanese it is known as tenji (点字), literally "dot characters". It transcribes Japanese more or less as it would be written in the hiragana or katakana syllabaries, without any provision for writing kanji.
The history of the alphabet goes back to the consonantal writing system used to write Semitic languages in the Levant during the 2nd millennium BCE. Nearly all alphabetic scripts used throughout the world today ultimately go back to this Semitic script. Its first origins can be traced back to a Proto-Sinaitic script developed in Ancient Egypt to represent the language of Semitic-speaking workers and slaves in Egypt. Unskilled in the complex hieroglyphic system used to write the Egyptian language, which required a large number of pictograms, they selected a small number of those commonly seen in their surroundings to describe the sounds, as opposed to the semantic values, of their own Canaanite language. This script was partly influenced by the older Egyptian hieratic, a cursive script related to Egyptian hieroglyphs. The Semitic alphabet became the ancestor of multiple writing systems across the Middle East, Europe, northern Africa, and Pakistan, mainly through Ancient South Arabian, Phoenician and the closely related Paleo-Hebrew alphabet, and later Aramaic and the Nabatean—derived from the Aramaic alphabet and developed into the Arabic alphabet—five closely related members of the Semitic family of scripts that were in use during the early first millennium BCE.
An inherent vowel is part of an abugida script. It is a vowel sound which is used with each unmarked or basic consonant symbol. For example, if the Latin alphabet used 'i' as an inherent vowel, "Wikipedia" could be rendered as "Wkpeda" [w(I)+k(I)+p+e+d(I)+a].
In a featural writing system, the shapes of the symbols are not arbitrary but encode phonological features of the phonemes that they represent. The term featural was introduced by Geoffrey Sampson to describe the Korean alphabet and Pitman shorthand.
The Aztec or Nahuatl script is a pre-Columbian writing system that combines ideographic writing with Nahuatl specific phonetic logograms and syllabic signs which was used in central Mexico by the Nahua people.
A semi-syllabary is a writing system that behaves partly as an alphabet and partly as a syllabary. The main group of semi-syllabic writing are the Paleohispanic scripts of ancient Spain, a group of semi-syllabaries that transform redundant plosive consonants of the Phoenician alphabet into syllabograms.
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).
A writing system comprises a particular set of symbols, called a script, as well as the rules by which the script represents a particular language. Writing systems can generally be classified according to how symbols function according to these rules, with the most common types being alphabets, syllabaries, and logographies. Alphabets use symbols called letters that correspond to spoken phonemes. Abjads generally only have letters for consonants, while pure alphabets have letters for both consonants and vowels. Abugidas use characters that correspond to consonant–vowel pairs. Syllabaries use symbols called syllabograms to represent syllables or moras. Logographies use characters that represent semantic units, such as words or morphemes.
Ditema tsa Dinoko, also known as ditema tsa Sesotho, is a constructed writing system for the siNtu or Southern Bantu languages. It is also known by its IsiZulu name isiBheqe soHlamvu, and by various other names in different languages. It was developed in the 2010s from antecedent ideographic traditions of the Southern African region. Its visual appearance is inspired by these, including the traditional litema arts style. It was developed between 2014 and 2016 by a group of South African linguists and software programmers with the goal of creating a denser writing system to avoid the slowness in reading caused by the word length and visual homogeneity of Southern Bantu languages written in the Roman alphabet. As of 2023, no proposal has been made to encode the script in Unicode, the text encoding standard designed to support all of the world's major writing systems.
