Lexicostatistics
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] |
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] |
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] |
Leipzig–Jakarta List
The Leipzig–Jakarta list of 100 words is used by linguists to test the degree of chronological separation of languages by comparing words that are resistant to borrowing. The Leipzig–Jakarta list became available in 2009. The word list is named after the cities of Leipzig, Germany, and Jakarta, Indonesia, the places where the list was conceived and created. In the 1950s, the linguist Morris Swadesh published a list of 200 words called the Swadesh list, allegedly the 200 lexical concepts found in all languages that were least likely to be borrowed from other languages. Swadesh later whittled his list down to 100 items. The Swadesh list, however, was based mainly on intuition, according to Martin Haspelmath and Uri Tadmor.Haspelmath & Tadmor, p. 72. In origin, the words in the Swadesh lists were chosen for their universal, culturally independent availability in as many languages as possible, regardless of their "stability". Nevertheless, the stability of the resulting list ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparative Method
In linguistics, the comparative method is a technique for studying the development of languages by performing a feature-by-feature comparison of two or more languages with common descent from a shared ancestor and then extrapolating backwards to infer the properties of that ancestor. The comparative method may be contrasted with the method of internal reconstruction in which the internal development of a single language is inferred by the analysis of features within that language. Ordinarily, both methods are used together to reconstruct prehistoric phases of languages; to fill in gaps in the historical record of a language; to discover the development of phonological, morphological and other linguistic systems and to confirm or to refute hypothesised relationships between languages. The comparative method emerged in the early 19th century with the birth of Indo-European studies, then took a definite scientific approach with the works of the Neogrammarians in the late 19th� ...

Morris Swadesh
Morris Swadesh ( ; January 22, 1909 – July 20, 1967) was an American linguist who specialized in comparative and historical linguistics, and developed his mature career at UNAM in Mexico. Swadesh was born in Massachusetts to Bessarabian Jewish immigrant parents. He completed bachelor's and master's degrees at the University of Chicago, studying under Edward Sapir, and then followed Sapir to Yale University where he completed a Ph.D. in 1933. Swadesh taught at the University of Wisconsin–Madison from 1937 to 1939, and then during World War II worked on projects with the United States Army and Office of Strategic Services. He became a professor at the City College of New York after the war's end, but was fired in 1949 due to his membership in the Communist Party. He spent most of the rest of his life teaching in Mexico and Canada. Swadesh had a particular interest in the indigenous languages of the Americas, and conducted extensive fieldwork throughout North America. He was ...

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] |
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] |
Loanword
A loanword (also a loan word, loan-word) is a word at least partly assimilated from one language (the donor language) into another language (the recipient or target language), through the process of borrowing. Borrowing is a metaphorical term that is well established in the linguistic field despite its acknowledged descriptive flaws: nothing is taken away from the donor language and there is no expectation of returning anything (i.e., the loanword). Loanwords may be contrasted with calques, in which a word is borrowed into the recipient language by being directly translated from the donor language rather than being adopted in (an approximation of) its original form. They must also be distinguished from cognates, which are words in two or more related languages that are similar because they share an etymological origin in the ancestral language, rather than because one borrowed the word from the other. Examples and related terms A loanword is distinguished from a calque (or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
