The language spoken by the residents of the country (and the official language of all the governmental and economic structures) is Persian, also known as Farsi or Western Persian. It appeared in the ninth century. Nowadays it is the national language of several countries, in Afghanistan and Tajikistan as well. The script of the language is derived from Arabic, but slightly modified. All the symbols besides numerals are written from right to left.
