Some Iranian languages have been in intensive contact with Turkic languages
for many centuries. Tajik and Uzbek are representative of the languages
that have co-existed in the Iranian-Turkic language contact in Central
Asia. Uzbek is a Turkic language that has Chaghatay as its literary
predecessor and is the 'state language' of the republic of Uzbekistan.
Tajik, on the other hand, is a South-West Iranian language which is
genetically closely related to such Iranian languages as Persian and Dari.
Most Tajik speakers are in Tajikistan and Uzbekistan; within the latter
Samarkand and Bukhara are particularly densely populated by Tajik speakers.
The cohabitation of Tajik speakers with Uzbek speakers has made Tajik-Uzbek
bilingualism the norm in much of this area. Bukhara is one of the cities
where Tajik-Uzbek bilingualism is most pronounced; virtually all Tajik
speakers in Bukhara are bilingual in Tajik and Uzbek.
This book contains transcriptions of recordings of the Tajik language used
by Bukharans who have had no formal education in/of Tajik. A large number
of linguistic features of Bukharan Tajik are considered to have emerged or
have been retained under the influence of Uzbek.
