The limits of my language mean the limits of my world. (Die Grenzen meiner Sprache bedeuten die Grenzen meiner Welt.)
Tajiki is a language of Tajikistan. Roughly 65% of the population there speak it as a first language.
Tajik (or Tajiki) is a language that has evolved from Persian, and is spoken mainly in Tajikistan (where it is the official language) and Uzbekistan. It is closely related to the Dari version of Persian spoken in Afghanistan, and some would consider the Persian languages of Tajikistan, Iran and Afghanistan to be dialects of one language.
There are roughly 5.3 million first-language speakers, in at least 7 territories. Political instability had led to the Tajik people moving into Russia, Kyrgyzstan, Kazakhstan, Ukraine and Turkmenistan.
