Azeri or Azerbaijani is a Turkic language spoken primarily by the Azerbaijani people, who live mainly in the Republic of Azerbaijan and in the Azerbaijan region of Iran. Azeri is an agglutinative language and thus modifies and produces words through the use of suffixes. This suffixation process is used to form various tenses (i.e., past, present, future, etc.) by adding personal verbal suffixes to the base form of a verb.
