Digraphia
In sociolinguistics, digraphia refers to the use of more than one writing system for the same language. Synchronic digraphia is the coexistence of two or more writing systems for the same language, while diachronic digraphia or sequential digraphia is the replacement of one writing system by another for a particular language. Hindustani, with an Urdu literary standard written in Urdu alphabet and a Hindi standard written in Devanagari, is one of the "textbook examples" of synchronic digraphia, cases where writing systems are used contemporaneously. An example of diachronic digraphia, where one writing system replaces another, occurs in the case of Turkish, for which the traditional Arabic writing system was replaced with a Latin-based system in 1928. Digraphia has implications in language planning, language policy, and language ideology. Terminology Etymology English ''digraphia'', like French ''digraphie'', etymologically derives from Greek ''di-'' ''δι-'' "twice" ...

Digraph (orthography)
A digraph () or digram is a pair of character (symbol), characters used in the orthography of a language to write either a single phoneme (distinct sound), or a sequence of phonemes that does not correspond to the normal values of the two characters combined. Some digraphs represent phonemes that cannot be represented with a single character in the writing system of a language, like in Spanish ''chico'' and ''ocho''. Other digraphs represent phonemes that can also be represented by single characters. A digraph that shares its pronunciation with a single character may be a relic from an earlier period of the language when the digraph had a different pronunciation, or may represent a distinction that is made only in certain dialects, like the English . Some such digraphs are used for purely etymology, etymological reasons, like in French. In some orthographies, digraphs (and occasionally trigraph (orthography), trigraphs) are considered individual letter (alphabet), letters, w ...

Ligature (writing)
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 and used in English and French, in which the letters and are joined for the first ligature and the letters and are joined for the second ligature. For stylistic and legibility reasons, and are often merged to create (where the tittle on the merges with the hood of the ); the same is true of and to create . The common ampersand, , developed from a ligature in which the handwritten Latin letters and (spelling , Latin for 'and') were combined. History The earliest known script Sumerian cuneiform and Egyptian hieratic both include many cases of character combinations that gradually evolve from ligatures into separately recognizable characters. Other notable ligatures, such as the Brahmic abugidas and the Germanic bind rune, figure prominently throughout ancient manuscripts. These new glyphs emerge alongside the prolife ...

Digraph (computing)
In computer programming, digraphs and trigraphs are sequences of two and three characters, respectively, that appear in source code and, according to a programming language's specification, should be treated as if they were single characters. Various reasons exist for using digraphs and trigraphs: keyboards may not have keys to cover the entire character set of the language, input of special characters may be difficult, text editors may reserve some characters for special use and so on. Trigraphs might also be used for some EBCDIC code pages that lack characters such as . History The basic character set of the C programming language is a subset of the ASCII character set that includes nine characters which lie outside the ISO 646 invariant character set. This can pose a problem for writing source code when the encoding (and possibly keyboard) being used does not support one or more of these nine characters. The ANSI C committee invented trigraphs as a way of entering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CIA Cryptonym
CIA cryptonyms are code names or code words used by the U.S. Central Intelligence Agency (CIA) to refer to projects, operations, persons, agencies, etc. Format of cryptonyms CIA cryptonyms sometimes contain a two character prefix called a digraph, which designates a geographical or functional area. Certain digraphs were changed over time; for example, the digraph for the Soviet Union changed at least twice. The rest is either an arbitrary dictionary word, or occasionally the digraph and the cryptonym combine to form a dictionary word (e.g., AEROPLANE) or can be read out as a simple phrase (e.g., WIBOTHER, read as "Why bother!"). Cryptonyms are sometimes written with a slash after the digraph, e.g., ZR/RIFLE, and sometimes in one sequence, e.g., ZRRIFLE. The latter format is the more common style in CIA documents. Examples from publications by former CIA personnel show that the terms "code name" and "cryptonym" can refer to the names of operations as well as to individual person ...

Bigram
A bigram or digram is a sequence of two adjacent elements from a string of tokens, which are typically letters, syllables, or words. A bigram is an ''n''-gram for ''n''=2. The frequency distribution of every bigram in a string is commonly used for simple statistical analysis of text in many applications, including in computational linguistics, cryptography, and speech recognition. ''Gappy bigrams'' or ''skipping bigrams'' are word pairs which allow gaps (perhaps avoiding connecting words, or allowing some simulation of dependencies, as in a dependency grammar). Applications Bigrams, along with other n-grams, are used in most successful language models for speech recognition. Bigram frequency attacks can be used in cryptography to solve cryptograms. See frequency analysis. Bigram frequency is one approach to statistical language identification. Some activities in logology or recreational linguistics involve bigrams. These include attempts to find English words beginning wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Romanized Popular Alphabet
The Romanized Popular Alphabet (RPA) or Hmong RPA (also Roman Popular Alphabet), is a system of romanization for the various dialects of the Hmong language. Created in Laos between 1951 and 1953 by a group of missionaries and Hmong advisers, it has gone on to become the most widespread system for writing the Hmong language in the West. It is also used in Southeast Asia and China alongside other writing systems, most notably Nyiakeng Puachue Hmong and Pahawh Hmong. History In Xiangkhoang Province, Protestant missionary G. Linwood Barney began working on the writing system with speakers of Green Mong (Mong Leng), Geu Yang and Tua Xiong, among others. He consulted with William A. Smalley, a missionary studying the Khmu language in Luang Prabang Province at the time. Concurrently, Yves Bertrais, a Roman Catholic missionary in Kiu Katiam, Luang Prabang, was undertaking a similar project with Chong Yeng Yang and Chue Her Thao. The two working groups met in 1952 and reconciled any di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
