Swahili language
The exact number of Swahili speakers, be it native or second-language speakers, is unknown and a matter of debate. Various estimates have been put forward and they vary widely, from 50 million to over 100 million. Swahili serves as a national language of four nations: Tanzania, Kenya, Uganda, and the DRC. Shikomor, the official language in Comoros and also spoken in Mayotte (), is related to Swahili. Swahili is also one of the working languages of the African Union and officially recognised as a lingua franca of the East African Community. South Africa legalized the teaching of Swahili in South African schools as an optional subject beginning in 2020.
The Kwere (Ngh'were) of Tanzania
The pervasive dominance of the Swahili language in coastal affairs throughout East Africa for many centuries have led to most peoples indigenous in the area to be at least bilingual, the Ngh'were are no different. This was confirmed in 2002 by Bagamoyo elders who attended a conference held in the city championing its nomination as a UNESCO World Heritage site. Recently, Bagamoyo was reported as the recipient of Tanzania’s seventh world heritage site. What impact this award will have on Ngh'were residency in the city is not yet known, but the tour handlers are advertising globally.
