comes from older *i (there is an alternation e/i before ) if the historical cluster *ih or *iع appears in a closed syllable, and *i changes to e. In open syllables, the change did not take place (that is similar to Tajik). The change can be seen in the verb dih-/deh-: infinitive vs. 3rd sg. present . In Yaghnobi dialects, there can be seen a different development of historical svarabhakti vowel: in the Western and Transitional dialects, it is rendered as (or under certain circumstances), but in the Eastern dialects it changes to (but also or ): *θray > *θəráy > W./Tr. tiráy vs. E. saráy but *βrāt > *vərāt > W./Tr./E. virót.When the second vowel is a back vowel, *ə usually changes to in Western or Transitional dialects: *(čə)θβār > *tfār > *təfór > W./Tr. tufór (but also tifór) vs. E. tafór, *pδūfs- > *bədū́fs > W./Tr./E. budū́fs-. The later change appears also in morphology: verb tifárak (the form is same in all three dialects) has form in 3rd sg. present tufórči < *təfár- < *tfar- < *θβar-. The alternation can be seen also in Tajik loans where an unstressed vowel can undergo this change: W./Tr. širī́k vs. E. šarī́k < Tajik /šarīk/ "partner", W./Tr. xipár vs. E. xapár < Tajik /xabar/ "news". The former svarabhakti vowels are often ultra-short or reduced in pronunciation, and they can even disappear in fast speech: xišáp /xišáp vs. xⁱšáp vs. xšap/ < *xəšáp < *xšap. The changes to in verbal stems of type -Car- if an ending containing historic *θ or *t is added: tifár-, infinitive tifárak, 1st sg. present tifarómišt but 3rd sg. present tufórči (ending -či comes from older -tišt), 2nd pl. present W./Tr. tufórtišt E. tufórsišt, x°ar-: x°árak : x°arómišt : xórči : xórtišt/xórsišt (when changes to after , loses its labilisation). The change takes place with all verbs of Yaghnobi origin and also with older loans from Tajik. For new loans, a remains unchanged.: gudár(ak) : gudórči vs. pár(ak) : párči: the first verb is an old loan from Tajik guzaštan < guδaštan, the later a recent loan from parrīdan.
