The present article describes the vowel chain shift that occurred in the variety of Tajik spoken by Jewish residents in Bukhara. It identifies the chain shift as constituting of an intermediate stage of the Northern Tajik chain shift and accordingly tentatively concludes that in the Northern Tajik chain shift Early New Persian ā shifted before ō did, shedding light on the process whereby the present-day Tajik vowel system was established. The article is divided into three parts. The first provides an explanation of the variety of Tajik spoken by Jewish inhabitants of Bukhara. The second section explains the relationship between this particular variety and other varieties that have been used by Jews in Central Asia. The third section deals specifically with the vowel system of the variety and the changes that it has undergone since the late 19th century.
