South of this area are languages of the Tsonga group, which are quite different again. XiTswa or Tswa occurs at the coast and inland, XiTsonga or Tsonga straddles the area around the Limpopo River, including such local dialects as XiHlanganu, XiN'walungu, XiBila, XiHlengwe, and XiDzonga. This language area extends into neighbouring South Africa. Still related to these, but distinct, are GiTonga, BiTonga, and CiCopi or Chopi, spoken north of the mouth of the Limpopo, and XiRonga or Ronga, spoken in the immediate region around Maputo. The languages in this group are, judging by the short vocabularies, very vaguely similar to Zulu, but obviously not in the same immediate group. There are small Swazi- and Zulu-speaking areas in Mozambique immediately next to the Swaziland and KwaZulu-Natal borders.
