Extinct language
–
An extinct language is a language that no longer has any speakers, especially if it has no living descendants. A dead language is one that is no longer the language of any community, even if it still in use. A language that currently has living native speakers is called a modern language, as of the 2000s, a total of roughly 7,000 natively spoken languages existed worldwide. Most of these are languages in danger of extinction, one estimate published in 2004 expected that some 90% of the currently spoken languages will have become extinct by 2050. Normally the transition from a spoken to an extinct language occurs when a language undergoes language death while being replaced by a different one. For example, some Native American languages were replaced by English, French, Portuguese, Spanish, such languages are sometimes also referred to as dead languages, but more typically as classical language. g. Old English or Old High German relative to their descendants, English. Minor languages are endangered due to economic and cultural globalization. Second, the gradual process of language death may occur over several generations. The third and most rare outcome is for the group to maintain as much of its native language as possible, while borrowing elements of the dominant languages grammar. Institutions such as the system, as well as forms of media such as the Internet, television. Language revival is the attempt to re-introduce a recently-extinct language in use by a new generation of native speakers. The optimistic neologism sleeping beauty languages has been used to such a hope. Hebrew is an example of a language that has successfully been revived for everyday use. The revival of Hebrew has been successful due to extraordinarily favourable conditions. Revival attempts of minor languages with no status as liturgical language typically have more modest results and this is a list of languages reported as having become extinct after the year 2000.

Language family
–
A language family is a group of languages related through descent from a common ancestral language or parental language, called the proto-language of that family. Linguists therefore describe the languages within a language family as being genetically related. Estimates of the number of living languages vary from 5,000 to 8,000, depending on the precision of ones definition of language, the 2013 edition of Ethnologue catalogs just over 7,000 living human languages. A living language is one that is used as the primary form of communication of a group of people. There are also dead and extinct languages, as well as some that are still insufficiently studied to be classified. Membership of languages in a family is established by comparative linguistics. Sister languages are said to have a genetic or genealogical relationship, speakers of a language family belong to a common speech community. The divergence of a proto-language into daughter languages typically occurs through geographical separation, individuals belonging to other speech communities may also adopt languages from a different language family through the language shift process. Genealogically related languages present shared retentions, that is, features of the proto-language that cannot be explained by chance or borrowing, for example, Germanic languages are Germanic in that they share vocabulary and grammatical features that are not believed to have been present in the Proto-Indo-European language. These features are believed to be innovations that took place in Proto-Germanic, language families can be divided into smaller phylogenetic units, conventionally referred to as branches of the family because the history of a language family is often represented as a tree diagram. A family is a unit, all its members derive from a common ancestor. Some taxonomists restrict the term family to a level. Those who affix such labels also subdivide branches into groups, a top-level family is often called a phylum or stock. The closer the branches are to other, the closer the languages will be related. For example, the Celtic, Germanic, Slavic, Romance, there is a remarkably similar pattern shown by the linguistic tree and the genetic tree of human ancestry that was verified statistically. Languages interpreted in terms of the phylogenetic tree of human languages are transmitted to a great extent vertically as opposed to horizontally. A speech variety may also be considered either a language or a dialect depending on social or political considerations, thus, different sources give sometimes wildly different accounts of the number of languages within a family. Classifications of the Japonic family, for example, range from one language to nearly twenty, most of the worlds languages are known to be related to others

International Phonetic Alphabet
–
The International Phonetic Alphabet is an alphabetic system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association as a representation of the sounds of spoken language. The IPA is used by lexicographers, foreign students and teachers, linguists, speech-language pathologists, singers, actors, constructed language creators. The IPA is designed to represent only those qualities of speech that are part of language, phones, phonemes, intonation. IPA symbols are composed of one or more elements of two types, letters and diacritics. For example, the sound of the English letter ⟨t⟩ may be transcribed in IPA with a letter, or with a letter plus diacritics. Often, slashes are used to signal broad or phonemic transcription, thus, /t/ is less specific than, occasionally letters or diacritics are added, removed, or modified by the International Phonetic Association. As of the most recent change in 2005, there are 107 letters,52 diacritics and these are shown in the current IPA chart, posted below in this article and at the website of the IPA. In 1886, a group of French and British language teachers, led by the French linguist Paul Passy, for example, the sound was originally represented with the letter ⟨c⟩ in English, but with the digraph ⟨ch⟩ in French. However, in 1888, the alphabet was revised so as to be uniform across languages, the idea of making the IPA was first suggested by Otto Jespersen in a letter to Paul Passy. It was developed by Alexander John Ellis, Henry Sweet, Daniel Jones, since its creation, the IPA has undergone a number of revisions. After major revisions and expansions in 1900 and 1932, the IPA remained unchanged until the International Phonetic Association Kiel Convention in 1989, a minor revision took place in 1993 with the addition of four letters for mid central vowels and the removal of letters for voiceless implosives. The alphabet was last revised in May 2005 with the addition of a letter for a labiodental flap, apart from the addition and removal of symbols, changes to the IPA have consisted largely in renaming symbols and categories and in modifying typefaces. Extensions to the International Phonetic Alphabet for speech pathology were created in 1990, the general principle of the IPA is to provide one letter for each distinctive sound, although this practice is not followed if the sound itself is complex. There are no letters that have context-dependent sound values, as do hard, finally, the IPA does not usually have separate letters for two sounds if no known language makes a distinction between them, a property known as selectiveness. These are organized into a chart, the chart displayed here is the chart as posted at the website of the IPA. The letters chosen for the IPA are meant to harmonize with the Latin alphabet, for this reason, most letters are either Latin or Greek, or modifications thereof. Some letters are neither, for example, the letter denoting the glottal stop, ⟨ʔ⟩, has the form of a question mark

Specials (Unicode block)
–
Specials is a short Unicode block allocated at the very end of the Basic Multilingual Plane, at U+FFF0–FFFF. Of these 16 codepoints, five are assigned as of Unicode 9, U+FFFD � REPLACEMENT CHARACTER used to replace an unknown, unrecognized or unrepresentable character U+FFFE <noncharacter-FFFE> not a character. FFFE and FFFF are not unassigned in the sense. They can be used to guess a texts encoding scheme, since any text containing these is by not a correctly encoded Unicode text. The replacement character � is a found in the Unicode standard at codepoint U+FFFD in the Specials table. It is used to indicate problems when a system is unable to render a stream of data to a correct symbol and it is usually seen when the data is invalid and does not match any character, Consider a text file containing the German word für in the ISO-8859-1 encoding. This file is now opened with an editor that assumes the input is UTF-8. The first and last byte are valid UTF-8 encodings of ASCII, therefore, a text editor could replace this byte with the replacement character symbol to produce a valid string of Unicode code points. The whole string now displays like this, f�r, a poorly implemented text editor might save the replacement in UTF-8 form, the text file data will then look like this, 0x66 0xEF 0xBF 0xBD 0x72, which will be displayed in ISO-8859-1 as f�r. Since the replacement is the same for all errors this makes it impossible to recover the original character, a better design is to preserve the original bytes, including the error, and only convert to the replacement when displaying the text. This will allow the text editor to save the original byte sequence and it has become increasingly common for software to interpret invalid UTF-8 by guessing the bytes are in another byte-based encoding such as ISO-8859-1. This allows correct display of both valid and invalid UTF-8 pasted together, Unicode control characters UTF-8 Mojibake Unicodes Specials table Decodeunicodes entry for the replacement character

Unicode
–
Unicode is a computing industry standard for the consistent encoding, representation, and handling of text expressed in most of the worlds writing systems. As of June 2016, the most recent version is Unicode 9.0, the standard is maintained by the Unicode Consortium. Unicodes success at unifying character sets has led to its widespread, the standard has been implemented in many recent technologies, including modern operating systems, XML, Java, and the. NET Framework. Unicode can be implemented by different character encodings, the most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same values in both UTF-8 and ASCII encoding, and up to four bytes for other characters. UCS-2 uses a 16-bit code unit for each character but cannot encode every character in the current Unicode standard, UTF-16 extends UCS-2, using one 16-bit unit for the characters that were representable in UCS-2 and two 16-bit units to handle each of the additional characters. Many traditional character encodings share a common problem in that they allow bilingual computer processing, Unicode, in intent, encodes the underlying characters—graphemes and grapheme-like units—rather than the variant glyphs for such characters. In the case of Chinese characters, this leads to controversies over distinguishing the underlying character from its variant glyphs. In text processing, Unicode takes the role of providing a unique code point—a number, in other words, Unicode represents a character in an abstract way and leaves the visual rendering to other software, such as a web browser or word processor. This simple aim becomes complicated, however, because of concessions made by Unicodes designers in the hope of encouraging a more rapid adoption of Unicode, the first 256 code points were made identical to the content of ISO-8859-1 so as to make it trivial to convert existing western text. For other examples, see duplicate characters in Unicode and he explained that he name Unicode is intended to suggest a unique, unified, universal encoding. In this document, entitled Unicode 88, Becker outlined a 16-bit character model, Unicode could be roughly described as wide-body ASCII that has been stretched to 16 bits to encompass the characters of all the worlds living languages. In a properly engineered design,16 bits per character are more than sufficient for this purpose, Unicode aims in the first instance at the characters published in modern text, whose number is undoubtedly far below 214 =16,384. By the end of 1990, most of the work on mapping existing character encoding standards had been completed, the Unicode Consortium was incorporated in California on January 3,1991, and in October 1991, the first volume of the Unicode standard was published. The second volume, covering Han ideographs, was published in June 1992, in 1996, a surrogate character mechanism was implemented in Unicode 2.0, so that Unicode was no longer restricted to 16 bits. The Microsoft TrueType specification version 1.0 from 1992 used the name Apple Unicode instead of Unicode for the Platform ID in the naming table, Unicode defines a codespace of 1,114,112 code points in the range 0hex to 10FFFFhex. Normally a Unicode code point is referred to by writing U+ followed by its hexadecimal number, for code points in the Basic Multilingual Plane, four digits are used, for code points outside the BMP, five or six digits are used, as required. Code points in Planes 1 through 16 are accessed as surrogate pairs in UTF-16, within each plane, characters are allocated within named blocks of related characters

South Africa
–
South Africa, officially the Republic of South Africa, is the southernmost country in Africa. South Africa is the 25th-largest country in the world by land area and it is the southernmost country on the mainland of the Old World or the Eastern Hemisphere. About 80 percent of South Africans are of Sub-Saharan African ancestry, divided among a variety of ethnic groups speaking different Bantu languages, the remaining population consists of Africas largest communities of European, Asian, and multiracial ancestry. South Africa is a multiethnic society encompassing a variety of cultures, languages. Its pluralistic makeup is reflected in the recognition of 11 official languages. The country is one of the few in Africa never to have had a coup détat, however, the vast majority of black South Africans were not enfranchised until 1994. During the 20th century, the black majority sought to recover its rights from the dominant white minority, with this struggle playing a role in the countrys recent history. The National Party imposed apartheid in 1948, institutionalising previous racial segregation, since 1994, all ethnic and linguistic groups have held political representation in the countrys democracy, which comprises a parliamentary republic and nine provinces. South Africa is often referred to as the Rainbow Nation to describe the multicultural diversity. The World Bank classifies South Africa as an economy. Its economy is the second-largest in Africa, and the 34th-largest in the world, in terms of purchasing power parity, South Africa has the seventh-highest per capita income in Africa. However, poverty and inequality remain widespread, with about a quarter of the population unemployed, nevertheless, South Africa has been identified as a middle power in international affairs, and maintains significant regional influence. The name South Africa is derived from the geographic location at the southern tip of Africa. Upon formation the country was named the Union of South Africa in English, since 1961 the long form name in English has been the Republic of South Africa. In Dutch the country was named Republiek van Zuid-Afrika, replaced in 1983 by the Afrikaans Republiek van Suid-Afrika, since 1994 the Republic has had an official name in each of its 11 official languages. Mzansi, derived from the Xhosa noun umzantsi meaning south, is a name for South Africa. South Africa contains some of the oldest archaeological and human fossil sites in the world, extensive fossil remains have been recovered from a series of caves in Gauteng Province. The area is a UNESCO World Heritage site and has termed the Cradle of Humankind
