South Oran Berber, or Tachelhit, is a cluster of the Zenati languages, which belong to the Berber branch of the Afroasiatic family. It is spoken in a number of oases of southwestern Algeria and across the border in Morocco.
Of these towns, the only one whose dialect has been studied in any detail is Figuig (Kossmann 1997). A cursory study of the northern dialects, including texts and vocabulary, is Basset (1885, 1886) while a sketch grammar of its southernmost member, Igli, is provided by Kossmann (2010). El Idrissi (2017) focuses mainly on phonetic variation among the different villages.
Like many other Berber varieties, the Figuig Berber dialects use bipartite verbal negation. The preverbal negator is ul (locally un, il); the postverbal negator is ša (Igli, Mazzer) / šay (Figuig, Iche, Moghrar) / iš (Boussemghoun, Ain Chair), with both the latter two appearing as allomorphs in Tiout. The numerals 1 and 2 are Berber, while higher numerals are Arabic borrowings throughout.
This language has no established name in English; in French literature it is referred to as Kçours du Sud-Oranais or parlers des Kçours Oranais et de Figuig. Its speakers most frequently call it by the vague term tacelḥit "Tashelhiyt" ("Shilha"), but in the northern villages the equally vague term tmaziɣt "Tamazight" is also used, while tabeldit is specific to the Igli area (El Idrissi 2017:22).
