Аннотация:The study aims at evaluating the adaptive potential of the Gogo language spoken in Dodoma, the capital region of Tanzania, amid drastic urbanization of the last decade. Historical review of the language ecology in the region helps to identify disturbing language contacts and the way the language responded to them, thus moving through the four phases of the adaptive cycle postulated by the theory of resilience linguistics: growth, conservation, release, and reorganization. The Bantu-Cushitic contact (fourteenth to seventeenth centuries) led to the emergence and growth of Gogo koine. The Bantu-Nilotic contact (eighteenth to nineteenth centuries) resulted in the growth (vocabulary expansion) and the conservation of the koine (retention of the achieved complexity). The Bantu-Bantu (Hehe) contact (nineteenth century) had, as its effects, both release and reorganization of the achieved complexity in the southern part of Gogo areal (amalgamation with Hehe and formation of the mixed language variety Citiliko) and growth and conservation of the language on the rest of its territory. The Gogo-Swahili/English vertical сontact (twentieth century) was the key to the release of the koine and the creation of the tribal and linguistic (that is ethnolinguistic) identity which serves as the backbone of the language’s vitality nowadays.
