Azerbaijani (/ˌæzərbaɪˈdʒɑːni/) or Azeri (/æˈzɛəri, ɑː-, ə-/), also referred to as Azeri Turkic, Azeri Turkish, is a Turkic language spoken primarily by the Azerbaijani people, who live mainly in the Republic of Azerbaijan where the North Azerbaijani variety is spoken, and in the Azerbaijan region of Iran, where the South Azerbaijani variety is spoken. Although there is a very high degree of mutual intelligibility between both forms of Azerbaijani, there are significant differences in phonology, lexicon, morphology, syntax and sources of loanwords.
