This study discusses the future of the Kisafwa ethnic community language spoken in Ituha village in light of the influence of the Kiswahili, the dominant language in Tanzania. The study uses a multidimensional approach where both the linguistic and socio-economic factors form the basis of analysis and interpretation. Considering assessment of the sociolinguistic profiles of Wasafwa at Ituha village and the patterns of language use and acquisition at home, it is evident that the speakers in Ituha village exhibit signs of language maintenance. The maintenance of the Kisafwa language is due to the fact that many young people and other age groups of both sexes still use the Kisafwa more than the Kiswahili. However, the study does not ignore the few speakers who use the Kiswahili because the trend of the patterns of language use and acquisition show that the percentage of the Kiswahili speakers in the domains of home and neighborhood increases with decreasing age groups. This implies that in future the number of the Kiswahili speakers may keep on rising at the expense of the Kisafwa language whose speakers will decrease. Thus, at a given time, language shift may take the lead over language maintenance.
