 The Matengo language is thus getting Swahilized gradually, and as result most of the younger generation tend to speak in Swahili.The Matengo people inhabit the southern highlands of Tanzania, a mountainous area of the country which ranges in altitude from 900 to 2000 metres above sea level.The land below an altitude of 1400 metres is generally open woodland known as miombo, with a heavy concentration of "Caesalpiniaceae" trees.
