Uzbek (Oʻzbek tili), a Turkic language, is the official language of the republic of Uzbekistan and also spoken regionally in nine provinces in northern Afghanistan.
Interestingly, modern Uzbek has a complicated system of dialects, with many conversational forms that are almost unrelated to each other.
The development of the Uzbek language was influenced by Sogdian, Tajiki Persian, Arabic and Russian.
The written form of Uzbek also has an interesting history. Until 1928 it used the Arabic alphabet, at which time it switched to Latin alphabet, and later, Cyrillic. Then in 1992, it officially started using Latin again, but in practice, the use of both Cyrillic and Latin scripts has continued in parallel.
