An alphabet is a standard set of letters written to represent particular sounds in a spoken language. Specifically, letters largely correspond to phonemes as the smallest sound segments 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 the 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.
Writing is the act of creating a persistent representation of human language. A writing system uses a set of symbols and rules to encode aspects of spoken language, such as its lexicon and syntax. However, written language may take on characteristics distinct from those of any spoken language.
Ancient Egyptian hieroglyphs were the formal writing system used in Ancient Egypt for writing the Egyptian language. Hieroglyphs combined ideographic, logographic, syllabic and alphabetic elements, with more than 1,000 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. Egyptian hieroglyphs are the ultimate ancestor of the Phoenician alphabet, the first widely adopted phonetic writing system. Moreover, owing in large part to the Greek and Aramaic scripts that descended from Phoenician, the majority of the world's living writing systems are descendants of Egyptian hieroglyphs—most prominently the Latin and Cyrillic scripts through Greek, and the Arabic and Brahmic scripts through Aramaic.
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. Syllabics are an abugida, where glyphs represent consonant–vowel pairs, determined by the rotation of the glyphs. They derive from the work of linguist and missionary James Evans.
Maya script, also known as Maya glyphs, is historically the native writing system of the Maya civilization of Mesoamerica and is the only Mesoamerican writing system that has been substantially deciphered. The earliest inscriptions found which are identifiably Maya date to the 3rd century BCE in San Bartolo, Guatemala. Maya writing was in continuous use throughout Mesoamerica until the Spanish conquest of the Maya in the 16th and 17th centuries. Though modern Mayan languages are almost entirely written using the Latin alphabet rather than Maya script, there have been recent developments encouraging a revival of the Maya glyph system.
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.
Ojibwe is an indigenous language of North America from the Algonquian language family. Ojibwe is one of the largest Native American languages north of Mexico in terms of number of speakers and is characterized by a series of dialects, some of which differ significantly. The dialects of Ojibwe are spoken in Canada from southwestern Quebec, through Ontario, Manitoba and parts of Saskatchewan, with outlying communities in Alberta and British Columbia, and in the United States from Michigan through Wisconsin and Minnesota, with a number of communities in North Dakota and Montana, as well as migrant groups in Kansas and Oklahoma.
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.
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).
In orthography, a zero consonant, silent initial, or null-onset letter is a consonant letter that does not correspond to a consonant sound, but is required when a word or syllable starts with a vowel. Some abjads, abugidas, and alphabets have zero consonants, generally because they have an orthographic rule that all syllables must begin with a consonant letter, whereas the language they transcribe allows syllables to start with a vowel. In a few cases, such as Pahawh Hmong below, the lack of a consonant letter represents a specific consonant sound, so the lack of a consonant sound requires a distinct letter to disambiguate.
A writing system comprises a set of symbols, called a script, as well as the rules by which the script represents a particular language. The earliest writing was invented during the late 4th millennium BC. Throughout history, each writing system invented without prior knowledge of writing gradually evolved from a system of proto-writing that included a small number of ideographs, which were not fully capable of encoding spoken language, and lacked the ability to express a broad range of ideas.
Geʽez Braille is a collection of braille alphabets for the Ethiopian languages that are written in Geʽez script in print. Letter values are mostly in line with international usage. At least the Amharic language is supported; perhaps the extended letters needed for Tigrinya, Tigre and possibly other Ethiopian languages are supported as well, but if so that is not recorded in available references.
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.
