The Tasmanian languages were the languages indigenous to the island of Tasmania, used by Aboriginal Tasmanians. The languages were last used for daily communication in the 1830s, although the terminal speaker, Fanny Cochrane Smith, survived until 1905.
Sources Tasmanian languages are attested by around three dozen word lists, the most extensive being those of Joseph Milligan and George Augustus Robinson. From the limited evidence, the sounds of Tasmanian appear to have been fairly typical of Australian languages. Plomley (1976) presents all the lexical data available to him in 1976. Crowley & Dixon (1981) summarise what little is known of Tasmanian phonology and grammar. Claire Bowern (2012) organises 35 different word lists and attempts to classify them into language families. Fanny Cochrane Smith recorded a series of wax cylinder recordings of Aboriginal songs, the only existing audio recording of a Tasmanian language, though they are of extremely poor quality. In 1972, her granddaughters still remembered some words and a song. Robert M. W. Dixon, who interviewed them as part of his research with Terry Crowley, concluded that "there is virtually no data on the grammar and no running text so that it is impossible to say very much of linguistic interest about the Tasmanian languages". However, from the scant sources that are available, Tasmanian people are seeking to recover their lost languages and traditions. The largest language revival project to date is the palawa kani project.
External classification Little is known of the languages and no relationship to other languages is demonstrable. It appears that there were several language families on Tasmania, which would be in keeping with the long period of human habitation on the island. In the 1970s Joseph Greenberg proposed an Indo-Pacific superfamily which includes Tasmanian along with Andamanese and Papuan (but not Australian). However, this superfamily proposal is rejected by the vast majority of historical linguists.
Languages and language families Based on short wordlists, it appears that there were anywhere from five to sixteen languages on Tasmania, related to one another in perhaps four language families. There are historical records as well that indicate the languages were not mutually intelligible and that a lingua franca was necessary for communication after resettlement on Flinders' Island. J.B. Walker, who visited the island in 1832 and 1834, reported:
Robert Clark, the catechist, states that on his arrival at the Flinders' Settlement in 1834, eight or ten different languages or dialects were spoken amongst the 200 natives then at the establishment, and that the blacks were 'instructing each other to speak their respective tongues'. Reports from the subsequent settlement at Oyster Cove were similar:
The Aboriginal dialects made it difficult for the members of one family to understand that of another; "now however they all seem to have merged into one" Schmidt (1952) distinguished five languages in the word lists:
The Eastern languages seem to share a common vocabulary, and use the nominal particle na. The Western languages use leā instead of na.
Crowley & Dixon (1981)
Crowley & Dixon (1981) reviewed the data. They evaluate 13 local varieties, and find 6 to 8 languages, with no conclusion on two additional varieties (those of the west coast) due to lack of data. Listed here (clockwise from the northwest) with their Australian Institute of Aboriginal and Torres Strait Islander Studies (AIATSIS) codes, they are:
North-western (T3) and Robbins Island (T11*) [northern NW region on the map displayed in the box above at right] North-western and Robbins Island are probably dialects of a single language; Circular Head may be a dialect as well. Although Circular Head (T12*) [NE strip of NW region on map] shares only half its vocabulary with Northwestern & Robbins Island, it cannot be ruled out as a dialect of the NW language due to the poor state of the data. Northern (T1) [N region on map] Probably a separate language, though it shares 50% of vocabulary with Piper River and cannot be ruled out as a dialect of the NE language. Port Sorell (T13*) [N coast of N Midlands region on map] It is "unlikely" there is a close genetic connection with any other Tasmanian language. Piper River (T14*), Cape Portland (T9*), and Ben Lomond (T7) [NE and Ben Lomond regions on map] These appear to form an interrelated group. Either the first two or all three could be dialects of a single language. May form a language with Northern, which is separated geographically by Port Sorell. North Midlands (T4) [central N Midlands region on map] "Must" be a distinct language. Oyster Bay (T2), Big River (T8*), and Little Swanport (T15*) [Oyster Bay and Big River on map] Oyster Bay and Big River share 85% of vocabulary and are very likely to be dialects. Little Swanport could be a dialect as well. South-eastern (T5) [SE region on map] Appears to be a distinct language from Oyster Bay / Big River. The two western varieties are South-western (T10*) and Macquarie Harbour (T6) [southern and northern ends of SW region on map]
Bowern (2012)
One of the difficulties in interpreting Tasmanian data is the fact that some of the 35 word lists mix data from various locations, and even for the rest, in some cases the location is not recorded. Bowern (2012) used a clustering algorithm to identify language admixture, and further techniques to conclude that the 26 unmixed lists with more than 100 words record twelve Tasmanian varieties (at p < 0.15) that may be assumed to be distinct languages. Due to the poor attestation, these varieties have no names apart from the names of the wordlists they are recorded in. They fall into five clusters; Bayesian phylogenetic methods demonstrate that two of these are clearly related, but that the others cannot be related to each other (that is, they are separate language families) based on existing evidence. Given the length of human habitation on Tasmania, it should not be expected for the languages to be demonstrably related to each other. The families, and the number of attested languages, are:
