Arrernte or Aranda (/ˈʌrəndə/;^[3] Eastern Arrernte pronunciation: [aɾəⁿɖə]) or sometimes referred to as Upper Arrernte (Upper Aranda), is a dialect cluster in the Arandic language group spoken in parts of the Northern Territory, Australia, by the Arrernte people. Other spelling variations are Arunta or Arrarnta, and all of the dialects have multiple other names.

There are about 1,800 speakers of Eastern/Central Arrernte, making this dialect one of the widest spoken of any Indigenous language in Australia, the one usually referred to as Arrernte and the one described in detail below. It is spoken in the Alice Springs area and taught in schools and universities, heard in media and used in local government.

The second biggest dialect in the group is Alyawarre. Some of the other dialects are spoken by very few people, leading to efforts to revive their usage; others are now completely extinct.

"Aranda" is a simplified, Australian English approximation of the traditional pronunciation of the name of Arrernte [ˈarəɳ͡ɖa].^[4]

Glottolog defines the Arandic group of languages/dialects as comprising 5 Aranda (Arrernte) dialects, plus two distinct languages, Kaytetye (Koch, 2004) and Lower Southern (or just Lower) Aranda, an extinct language.^[5] Ethnologue defines 8 Arandic languages and classifies them slightly differently.^[6]

Two dialects are more widely spoken than any of the others:

• Eastern Arrernte (also known as Central Arrernte) dialects include Akarre, Antekerrepenh, Ikngerripenhe, Mparntwe Arrernte.^[7] Spoken in the Alice Springs area and others, there were 1,910 speakers in the 2016 census,^[8] making it the most widely spoken Arrernte, and Australian Aboriginal, language. This is the dialect most often referred to as "Arrernte" and the strongest of all in the group. There is a project encouraging its use, Apmere angkentye-kenhe,^[9]
• Alyawarra dialect is spoken by the Alyawarra people, in the Sandover and Tennant Creek areas as well as Queensland. In 2016 there were 1,550 speakers of the language, giving it a status of "Developing".^[10] It is similar to Western Arrernte. (Kaytetye is related to this dialect, but is classed as a separate language.^[11])

All of the other dialects are either threatened or extinct:

• Andegerebinha (or Antekerrepenhe or Ayerrerenge) was spoken in the Hay River area (east of Alice Springs), but is now extinct.^[12]
  • Ayerrerenge, (also known as Yuruwinga, Bularnu and other variations) was spoken by the Yuruwinga/Yaroinga people^[13] is the north-easternmost member of the Arrernte group of languages, and the least studied.^[11] It was spoken across the Queensland border in the Headingly, Urandangi, Lake Nash, Barkly Downs and Mount Isa areas, and near Mount Hogarth, Bathurst,^[14] and

Argadargada^[15] in the NT.^[16] It is now extinct.^{[16][lower-alpha 1]} Breen (2001) says that the language was regarded as the same or similar to Andegerebinha/Antekerrepenhe by some speakers,^[11] and Glottolog regards it as a dialect of it.^[12]

• Anmatyerr (also spelt Anmatyerre and other variations),^[17] divided into Eastern and Western, is spoken by the Anmatyerr (or Anmatjirra) people.^[18] The Eastern form seems more closely related to Eastern Arrernte and Southern Alywarre than Western Anmatyerre, which is noticeably different phonetically from other Arandic languages.^[11] it is spoken in the Mount Allan and northwest Alice Springs regions. With only 640 speakers in the 2016 census, it is regarded as threatened.^[19]
• Western Arrarnta (Western Arrernte, Western Aranda, Akara, Southern Aranda, possible sub-dialect Akerre^[20]), spoken west of Alice Springs, is nearly extinct, being only spoken by 440 people in 2016.^[21] Other terms are Tyuretye Arrernte and Arrernte Alturlerenj.^{[22][lower-alpha 2][lower-alpha 3]} Breen distinguishes Tyurretye Arrernte (which he initially called Mbunghara) from Western Arrernte, saying that two speakers first recorded, from the Standley Chasm and Mbunghara, was not known until the mid-1980s, and that it may have been the "real" Western Arrernte, before the latter was mixed with Southern Arrernte (Pertame) at the Hermannsburg Mission.^[11] Anna Kenny has noted that the people of the Upper Finke River prefer their language to be known as Western Aranda.^[25] This dialect has similarities with Alyawarre and Kaytetye.

The Northern Territory Department of Education has a program for teaching Indigenous culture and languages, underpinned by a plan entitled Keeping Indigenous Languages and Cultures Strong – A Plan for Teaching and Learning of Indigenous Languages and Cultures in the Northern Territory with the second stage of the plan running from 2018 to 2020.^[27][28]

The Alice Springs Language Centre delivers language teaching at primary, middle and senior schools, offering Arrernte, Indonesian, Japanese, Spanish and Chinese.^[29]

There are two courses teaching Arrernte at tertiary level: at the Batchelor Institute and at Charles Darwin University.^[30]

There are books available in Arandic languages in the Living Archive of Aboriginal Languages.^[31]

Projects are being run to revive dying dialects of the language, such as Southern Arrernte/Pertame.^[32]

• Peter Sculthorpe's music theatre work Rites of Passage (1972–1973) is written partly in Arrernte and partly in Latin.
• Western and Southern Arrernte were used in parts of the libretto for Andrew Schultz' and Gordon Williams' Journey to Horseshoe Bend, based on the novel by Ted Strehlow.
