The various dialects of Tswana, Southern Sotho and Northern Sotho are highly mutually intelligible. On more than one occasion, proposals have been put forward to create a unified standardisation and declare a Sotho-Tswana language.
Northern Sotho, which appears largely to be a taxonomic holding category for what is Sotho-Tswana but neither identifiably Southern Sotho nor Tswana,[3] subsumes highly varied dialects including Pedi (Sepedi), Tswapo (Setswapo), Lovedu (Khilobedu), Pai and Pulana. Maho (2002) leaves the "East Sotho" varieties of Kutswe, Pai, and Pulana unclassified within Sotho-Tswana.
Sample
The Lord's Prayer in the various Sotho-Tswana languages.
English: Our Father in heaven, hallowed be your name, your kingdom come, your will be done, on earth as it is in heaven.
Pedi: Tatewešo wa magodimong, leina la gago a le kgethwe, mmušo wa gago a o tle, thato ya gago a e dirwe mo lefaseng bjalo ka ge e dirwa legodimong.
Sotho: Ntata rona ea maholimong, lebitso la hao le halaletsoe, ho tle muso oa hao, thato ea hao e etsoe lefaseng, joalo ka ha e etsoa leholimong.
Tswana: Rara wa rona yo o kwa legodimong, leina la gago a le itshepisiwe, puso ya gago a e tle, thato ya gago a e dirwe mo lefatsheng jaaka kwa legodimong.
Lozi: Ndat’a luna ya kwa lihalimu, libizo la hao li be le li kenile. Ku tahe mubuso wa hao. Se si latwa ki wena si ezwe mwa lifasi, sina mo si ezezwa mwa lihalimu.
