In historical linguistics , the wave model or wave theory ( German : Wellentheorie ) is a model of language change in which a new language feature (innovation) or a new combination of language features spreads from its region of origin, being adopted by a gradually expanding cluster of dialects. Each innovation starts at a certain place, and spreads from speaker to speaker, from dialect to dialect, in the same fashion as waves on the water.
34-674: Lambadi , Lambani , Lamani or Banjari is a Western Indo-Aryan language spoken by the Banjara people across India . The language does not have a native script. Regional dialects are divided between the Banjara of Maharashtra (written in Devanagari ), Karnataka (written in the Kannada script ), Tamil Nadu (written in the Tamil script ) and Andhra Pradesh , Telangana (written in
68-532: A lexicostatistical study of the New Indo-Aryan languages based on a 100-word Swadesh list , using techniques developed by the glottochronologist and comparative linguist Sergei Starostin . That grouping system is notable for Kogan's exclusion of Dardic from Indo-Aryan on the basis of his previous studies showing low lexical similarity to Indo-Aryan (43.5%) and negligible difference with similarity to Iranian (39.3%). He also calculated Sinhala–Dhivehi to be
102-819: A branch of the Indo-Iranian languages in the Indo-European language family . As of the early 21st century, they have more than 800 million speakers, primarily concentrated east of the Indus river in Bangladesh , North India , Eastern Pakistan , Sri Lanka , Maldives and Nepal . Moreover, apart from the Indian subcontinent , large immigrant and expatriate Indo-Aryan–speaking communities live in Northwestern Europe , Western Asia , North America ,
136-499: A standardised and Sanskritised register of Dehlavi , is the official language of the Government of India (along with English ). Together with Urdu , it is the third most-spoken language in the world. The Eastern Indo-Aryan languages, also known as Magadhan languages, are spoken throughout the eastern subcontinent, including Odisha and Bihar , alongside other regions surrounding the northwestern Himalayan corridor. Bengali
170-613: A subfamily of Indo-Aryan. The Dardic group as a genetic grouping (rather than areal) has been scrutinised and questioned to a degree by recent scholarship: Southworth, for example, says "the viability of Dardic as a genuine subgroup of Indo-Aryan is doubtful" and "the similarities among [Dardic languages] may result from subsequent convergence". The Dardic languages are thought to be transitional with Punjabi and Pahari (e.g. Zoller describes Kashmiri as "an interlink between Dardic and West Pahāṛī"), as well as non-Indo-Aryan Nuristani; and are renowned for their relatively conservative features in
204-450: A way that the genealogical subgroups they define form an intersected pattern. This explains the popularity of the Wave model in studies of dialectology . Johannes Schmidt used a second metaphor to explain the formation of a language from a continuum. The continuum is at first like a smooth, sloping line. Speakers in close proximity tend to unify their speech, creating a stepped line out of

272-656: Is in many cases somewhat arbitrary. The classification of the Indo-Aryan languages is controversial, with many transitional areas that are assigned to different branches depending on classification. There are concerns that a tree model is insufficient for explaining the development of New Indo-Aryan, with some scholars suggesting the wave model . The following table of proposals is expanded from Masica (1991) (from Hoernlé to Turner), and also includes subsequent classification proposals. The table lists only some modern Indo-Aryan languages. Anton I. Kogan , in 2016, conducted
306-577: Is suggested that "proto-Munda" languages may have once dominated the eastern Indo-Gangetic Plain , and were then absorbed by Indo-Aryan languages at an early date as Indo-Aryan spread east. Marathi-Konkani languages are ultimately descended from Maharashtri Prakrit , whereas Insular Indo-Aryan languages are descended from Elu Prakrit and possess several characteristics that markedly distinguish them from most of their mainland Indo-Aryan counterparts. Insular Indo-Aryan languages (of Sri Lanka and Maldives ) started developing independently and diverging from
340-420: Is the earliest stage of the Indo-Aryan branch, from which all known languages of the later stages Middle and New Indo-Aryan are derived, some documented Middle Indo-Aryan variants cannot fully be derived from the documented form of Old Indo-Aryan (on which Vedic and Classical Sanskrit are based), but betray features that must go back to other undocumented dialects of Old Indo-Aryan. Wave model The theory
374-620: Is the official language of Gujarat , and is spoken by over 50 million people. In Europe, various Romani languages are spoken by the Romani people , an itinerant community who historically migrated from India. The Western Indo-Aryan languages are thought to have diverged from their northwestern counterparts, although they have a common antecedent in Shauraseni Prakrit . Within India, Central Indo-Aryan languages are spoken primarily in

#1732798667503408-492: Is the only way to explain the nested organisation of subgroups imposed by the tree structure. Such a requirement is absent from the Wave Model, which can easily accommodate a distribution of innovations in intersected patterns. Such a configuration is typical of dialect continua (and of linkages , see below), that is, historical situations in which dialects share innovations with different neighbours simultaneously, in such
442-567: Is the seventh most-spoken language in the world, and has a strong literary tradition; the national anthems of India and Bangladesh are written in Bengali. Assamese and Odia are the official languages of Assam and Odisha , respectively. The Eastern Indo-Aryan languages descend from Magadhan Apabhraṃśa and ultimately from Magadhi Prakrit . Eastern Indo-Aryan languages display many morphosyntactic features similar to those of Munda languages , while western Indo-Aryan languages do not. It
476-661: Is vehement" (Mayrhofer, Etym. Wb., I 686, I 736). The earliest evidence of the group is from Vedic Sanskrit , that is used in the ancient preserved texts of the Indian subcontinent , the foundational canon of the Hindu synthesis known as the Vedas . The Indo-Aryan superstrate in Mitanni is of similar age to the language of the Rigveda , but the only evidence of it is a few proper names and specialized loanwords. While Old Indo-Aryan
510-745: The Caribbean , Southeast Africa , Polynesia and Australia , along with several million speakers of Romani languages primarily concentrated in Southeastern Europe . There are over 200 known Indo-Aryan languages. Modern Indo-Aryan languages descend from Old Indo-Aryan languages such as early Vedic Sanskrit , through Middle Indo-Aryan languages (or Prakrits ). The largest such languages in terms of first-speakers are Hindi–Urdu ( c. 330 million ), Bengali (242 million), Punjabi (about 150 million), Marathi (112 million), and Gujarati (60 million). A 2005 estimate placed

578-409: The tree model approach of the comparative method . Some scholars have even proposed that the wave model does not complement the tree model but should replace it for the representation of language genealogy . The recent works have also focused on the notion of a linkage , a family of languages descended from a former dialect continuum; linkages cannot be represented by trees and must be analysed by
612-750: The Mittani are either in Hurrian (which appears to have been the predominant language of their kingdom) or Akkadian (the main diplomatic language of the Late Bronze Age Near East), these apparently Indo-Aryan names suggest that an Indo-Aryan elite imposed itself over the Hurrians in the course of the Indo-Aryan expansion . If these traces are Indo-Aryan, they would be the earliest known direct evidence of Indo-Aryan, and would increase
646-612: The context of Proto-Indo-Aryan . The Northern Indo-Aryan languages , also known as the Pahari ('hill') languages, are spoken throughout the Himalayan regions of the subcontinent. Northwestern Indo-Aryan languages are spoken in the northwestern region of India and eastern region of Pakistan. Punjabi is spoken predominantly in the Punjab region and is the official language of the northern Indian state of Punjab , in addition to being
680-471: The continental Indo-Aryan languages from around 5th century BCE. The following languages are otherwise unclassified within Indo-Aryan: Dates indicate only a rough time frame. Proto-Indo-Aryan (or sometimes Proto-Indic ) is the reconstructed proto-language of the Indo-Aryan languages. It is intended to reconstruct the language of the pre-Vedic Indo-Aryans . Proto-Indo-Aryan is meant to be
714-405: The horse race). The numeral aika "one" is of particular importance because it places the superstrate in the vicinity of Indo-Aryan proper as opposed to Indo-Iranian in general or early Iranian (which has aiva ). Another text has babru ( babhru , "brown"), parita ( palita , "grey"), and pinkara ( pingala , "red"). Their chief festival was the celebration of the solstice ( vishuva ) which

#1732798667503748-502: The most divergent Indo-Aryan branch. Nevertheless, the modern consensus of Indo-Aryan linguists tends towards the inclusion of Dardic based on morphological and grammatical features. The Inner–Outer hypothesis argues for a core and periphery of Indo-Aryan languages, with Outer Indo-Aryan (generally including Eastern and Southern Indo-Aryan, and sometimes Northwestern Indo-Aryan, Dardic and Pahari ) representing an older stratum of Old Indo-Aryan that has been mixed to varying degrees with
782-582: The most widely-spoken language in Pakistan. Sindhi and its variants are spoken natively in the Pakistani province of Sindh and neighbouring regions. Northwestern languages are ultimately thought to be descended from Shauraseni Prakrit , with influence from Persian and Arabic . Western Indo-Aryan languages are spoken in central and western India, in states such as Madhya Pradesh and Rajasthan , in addition to contiguous regions in Pakistan. Gujarati
816-542: The newer stratum that is Inner Indo-Aryan. It is a contentious proposal with a long history, with varying degrees of claimed phonological and morphological evidence. Since its proposal by Rudolf Hoernlé in 1880 and refinement by George Grierson it has undergone numerous revisions and a great deal of debate, with the most recent iteration by Franklin Southworth and Claus Peter Zoller based on robust linguistic evidence (particularly an Outer past tense in -l- ). Some of
850-651: The precision in dating the split between the Indo-Aryan and Iranian languages (as the texts in which the apparent Indicisms occur can be dated with some accuracy). In a treaty between the Hittites and the Mitanni, the deities Mitra , Varuna , Indra , and the Ashvins ( Nasatya ) are invoked. Kikkuli 's horse training text includes technical terms such as aika (cf. Sanskrit eka , "one"), tera ( tri , "three"), panza ( panca , "five"), satta ( sapta , seven), na ( nava , "nine"), vartana ( vartana , "turn", round in
884-581: The predecessor of Old Indo-Aryan (1500–300 BCE), which is directly attested as Vedic and Mitanni-Aryan . Despite the great archaicity of Vedic, however, the other Indo-Aryan languages preserve a small number of conservative features lost in Vedic . Some theonyms, proper names, and other terminology of the Late Bronze Age Mitanni civilization of Upper Mesopotamia exhibit an Indo-Aryan superstrate. While what few written records left by
918-429: The sloped line. These steps are the dialects. Over the course of time, some steps become weak and fall into disuse , while others preempt the entire continuum. As an example, Schmidt used Standard German , which was defined to conform to some dialects and then spread throughout Germany, replacing the local dialects in many cases. In modern linguistics, the wave model has contributed greatly to improve, but not supersede,
952-444: The study of dialect continua and areal phenomena; it has recently gained more popularity among historical linguists, due to the shortcomings of the tree model. The tree model requires languages to evolve exclusively through social splitting and linguistic divergence. In the “tree” scenario, the adoption of certain innovations by a group of dialects should result immediately in their loss of contact with other related dialects: this
986-545: The theory's skeptics include Suniti Kumar Chatterji and Colin P. Masica . The below classification follows Masica (1991) , and Kausen (2006) . Percentage of Indo-Aryan speakers by native language: The Dardic languages (also Dardu or Pisaca) are a group of Indo-Aryan languages largely spoken in the northwestern extremities of the Indian subcontinent. Dardic was first formulated by George Abraham Grierson in his Linguistic Survey of India but he did not consider it to be
1020-402: The total number of native speakers of the Indo-Aryan languages at nearly 900 million people. Other estimates are higher suggesting a figure of 1.5 billion speakers of Indo-Aryan languages. The Indo-Aryan family as a whole is thought to represent a dialect continuum , where languages are often transitional towards neighboring varieties. Because of this, the division into languages vs. dialects
1054-418: The wave model. In A Thousand Plateaus , Deleuze and Guattari explicitly oppose arborescent models of language, instead opting for rhizomatic models that function like waves. They write: "Language stabilizes around a parish, a bishopric, a capital. It forms a bulb. It evolves by subterranean stems and flows, along river valleys or train tracks; it spreads like a patch of oil." Despite these similarities,

1088-554: The western Gangetic plains , including Delhi and parts of the Central Highlands , where they are often transitional with neighbouring lects. Many of these languages, including Braj and Awadhi , have rich literary and poetic traditions. Urdu , a Persianised derivative of Dehlavi descended from Shauraseni Prakrit , is the official language of Pakistan and also has strong historical connections to India , where it also has been designated with official status. Hindi ,
1122-587: Was common in most cultures in the ancient world. The Mitanni warriors were called marya , the term for "warrior" in Sanskrit as well; note mišta-nnu (= miẓḍha , ≈ Sanskrit mīḍha ) "payment (for catching a fugitive)" (M. Mayrhofer, Etymologisches Wörterbuch des Altindoarischen , Heidelberg, 1986–2000; Vol. II:358). Sanskritic interpretations of Mitanni royal names render Artashumara ( artaššumara ) as Ṛtasmara "who thinks of Ṛta " (Mayrhofer II 780), Biridashva ( biridašṷa, biriiašṷ a) as Prītāśva "whose horse
1156-477: Was intended as a substitute for the tree model , which did not seem to be able to explain the existence of some features, especially in the Germanic languages , by descent from a proto-language . At its most ambitious, it is a wholesale replacement for the tree model of languages. During the 20th century, the wave model had little acceptance as a model for language change overall, except for certain cases, such as
