Lexicostatistical
Lexicostatistics is a method of comparative linguistics that involves comparing the percentage of lexical cognates between languages to determine their relationship. Lexicostatistics is related to the comparative method but does not reconstruct a proto-language. It is to be distinguished from glottochronology, which attempts to use lexicostatistical methods to estimate the length of time since two or more languages diverged from a common earlier proto-language. This is merely one application of lexicostatistics, however; other applications of it may not share the assumption of a constant rate of change for basic lexical items. The term "lexicostatistics" is misleading in that mathematical equations are used but not statistics. Other features of a language may be used other than the lexicon, though this is unusual. Whereas the comparative method used shared identified innovations to determine sub-groups, lexicostatistics does not identify these. Lexicostatistics is a distance-based ...

Glottochronology
Glottochronology (from Attic Greek γλῶττα ''tongue, language'' and χρόνος ''time'') is the part of lexicostatistics which involves comparative linguistics and deals with the chronological relationship between languages.Sheila Embleton (1992). Historical Linguistics: Mathematical concepts. In W. Bright (Ed.), ''International Encyclopedia of Linguistics'' The idea was developed by Morris Swadesh in the 1950s in his article on Salish internal relationships. He developed the idea under two assumptions: there indeed exists a relatively stable ''basic vocabulary'' (referred to as ''Swadesh lists'') in all languages of the world; and, any replacements happen in a way analogous to radioactive decay in a constant percentage per time elapsed. Using mathematics and statistics, Swadesh developed an equation to determine when languages separated and give an approximate time of when the separation occurred. His methods aimed to aid linguistic anthropologists by giving them a defini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Kruskal
Joseph Bernard Kruskal, Jr. (; January 29, 1928 – September 19, 2010) was an American mathematician, statistician, computer scientist and psychometrician. Personal life Kruskal was born to a Jewish family in New York City to a successful fur wholesaler, Joseph B. Kruskal, Sr. His mother, Lillian Rose Vorhaus Kruskal Oppenheimer, became a noted promoter of origami during the early era of television. Kruskal had two notable brothers, Martin David Kruskal, co-inventor of solitons, and William Kruskal, who developed the Kruskal–Wallis one-way analysis of variance. One of Joseph Kruskal's nephews is notable computer scientist and professor Clyde Kruskal. Education and career He was a student at the University of Chicago earning a bachelor of science in mathematics in 1948, and a master of science in mathematics in the following year. After his time at the University of Chicago Kruskal attended Princeton University, where he completed his Ph.D. in 1954, nominally under ...

Swadesh List
A Swadesh list () is a compilation of cultural universal, tentatively universal concepts for the purposes of lexicostatistics. That is, a Swadesh list is a list of forms and concepts which all languages, without exception, have terms for, such as star, hand, water, kill, sleep, and so forth. The number of such terms is small – a few hundred at most, or possibly less than a hundred. The inclusion or exclusion of many terms is subject to debate among linguists; thus, there are several different lists, and some authors may refer to "Swadesh lists." The Swadesh list is named after linguist Morris Swadesh. Translations of a Swadesh list into a set of languages allow for researchers to quantify the interrelatedness of those languages. Swadesh lists are used in lexicostatistics (the quantitative assessment of the genealogical relatedness of languages) and glottochronology (the dating of language divergence). For instance, the terms on a Swadesh list can be compared between two languages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austronesian Languages
The Austronesian languages ( ) are a language family widely spoken throughout Maritime Southeast Asia, parts of Mainland Southeast Asia, Madagascar, the islands of the Pacific Ocean and Taiwan (by Taiwanese indigenous peoples). They are spoken by about 328 million people (4.4% of the world population). This makes it the fifth-largest language family by number of speakers. Major Austronesian languages include Malay (around 250–270 million in Indonesia alone in its own literary standard named " Indonesian"), Javanese, Sundanese, Tagalog (standardized as Filipino), Malagasy and Cebuano. According to some estimates, the family contains 1,257 languages, which is the second most of any language family. In 1706, the Dutch scholar Adriaan Reland first observed similarities between the languages spoken in the Malay Archipelago and by peoples on islands in the Pacific Ocean. In the 19th century, researchers (e.g. Wilhelm von Humboldt, Herman van der Tuuk) started to apply the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Languages
The number of languages natively spoken in Africa is variously estimated (depending on the delineation of language vs. dialect) at between 1,250 and 2,100, and by some counts at over 3,000. Nigeria alone has over 500 languages (according to SIL Ethnologue), one of the greatest concentrations of linguistic diversity in the world. The languages of Africa belong to many distinct language families, among which the largest are: * Niger–Congo, which include the large Atlantic-Congo and Bantu branches in West, Central, Southeast and Southern Africa. *Afroasiatic languages are spread throughout Western Asia, North Africa, the Horn of Africa and parts of the Sahel. * Saharan, Nilotic and Central Sudanic languages (previously grouped under the hypothetical Nilo-Saharan macro-family), are present in East Africa and Sahel. *Austronesian languages are spoken in Madagascar and parts of the Comoros. * Khoe–Kwadi languages are spoken mostly in Namibia and Botswana. *Indo-European ...

Phylogenetics
In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology. The results are a phylogenetic tree—a diagram depicting the hypothetical relationships among the organisms, reflecting their inferred evolutionary history. The tips of a phylogenetic tree represent the observed entities, which can be living taxa or fossils. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the taxa represented on the tree. An unrooted tree diagram (a network) makes no assumption about directionality of character state transformation, and does not show the origin or "root" of the taxa in question. In addition to their use for inferring phylogenetic pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paman Languages
The Paman languages are an Australian language family spoken on Cape York Peninsula, Queensland. First noted by Kenneth Hale, Paman is noteworthy for the profound phonological changes which have affected some of its descendants. Classification Various classifications of the Paman languages exist. The one outlined below is that of R. M. W. Dixon, though he does not accept that these branches are necessarily related to each other.See Dixon (2002), pp. xxx–xlii. Geographically, running down the east coast, they are: * North Cape York ** Northern Paman ** Umpila * Umbindhamu *Lamalamic ** Umbuygamu ** Lamu-Lamu * Yalgawarra *Yalanjic ** Guugu Yimithirr ** Guugu Yalandji ** Barrow Point (>> Wik?) * Mbariman-Gudhinma * Djabugay Down the west coast, they are: * North Cape York **Northern Paman ** Wik * Southwestern **Upper Southwest Paman *** Kuuk Thaayorre *** Kuuk Yak *** Kunjen (incl. Ogh Undjan) **Yir-Yoront The Yir-Yoront, also known as the Yir Yiront, ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparative Linguistics
Comparative linguistics is a branch of historical linguistics that is concerned with comparing languages to establish their historical relatedness. Genetic relatedness implies a common origin or proto-language and comparative linguistics aims to construct language families, to reconstruct proto-languages and specify the changes that have resulted in the documented languages. To maintain a clear distinction between attested and reconstructed forms, comparative linguists prefix an asterisk to any form that is not found in surviving texts. A number of methods for carrying out language classification have been developed, ranging from simple inspection to computerised hypothesis testing. Such methods have gone through a long process of development. Methods The fundamental technique of comparative linguistics is to compare phonological systems, morphological systems, syntax and the lexicon of two or more languages using techniques such as the comparative method. In principle, eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hunter-gatherer
A hunter-gatherer or forager is a human living in a community, or according to an ancestrally derived Lifestyle, lifestyle, in which most or all food is obtained by foraging, that is, by gathering food from local naturally occurring sources, especially wild edible plants but also insects, Fungus, fungi, Honey hunting, honey, Eggs as food, bird eggs, or anything safe to eat, or by hunting game (pursuing or trapping and killing Wildlife, wild animals, including Fishing, catching fish). This is a common practice among most vertebrates that are omnivores. Hunter-gatherer Society, societies stand in contrast to the more Sedentism, sedentary Agrarian society, agricultural societies, which rely mainly on cultivating crops and raising domesticated animals for food production, although the boundaries between the two ways of living are not completely distinct. Hunting and gathering was humanity's original and most enduring successful Competition (biology), competitive adaptation in the nat ...

Harry Hoijer
Harry Hoijer (September 6, 1904 – March 11, 1976) was a linguist and anthropologist who worked on primarily Athabaskan languages and culture. He additionally documented the Tonkawa language, which is now extinct language, extinct. Hoijer's few works make up the bulk of material on this language. Hoijer was a student of Edward Sapir. Hoijer contributed greatly to the documentation of the Southern Athabaskan languages, Southern and Pacific Coast Athabaskan languages and to the reconstruction of proto-Athabaskan. Harry Hoijer collected a large number of valuable fieldnotes on many Athabaskan languages, which are unpublished. Some of his notes on Lipan Apache people, Lipan Apache and the Tonkawa language are lost. Hoijer coined the term "Sapir–Whorf hypothesis"."The Sapir–Whorf hypothesis", in Hoijer (1954), pp. 92–105 Notes Bibliography * * * Earle, Timothy (ed.)
