What is "armeno-tats"

Armeno-Tats ( – hay-tater) are a distinct group of Tat-speaking Armenians that historically populated eastern parts of the South Caucasus. Most scholars researching the Tat language, such as Boris Miller and Igrar Aliyev, agree that Armeno-Tats are ethnic Armenians who underwent a language shift and adopted Tat as their first language. This is explained on one hand by the self-identification of Armeno-Tats who stated during Miller's research that they consider themselves Armenian as well as by some linguistic features of their dialect.
