Towards the classification of nominal forms in South-Western Iranian

In order to correct existing systems of description of word inflection in closely related southwestern Iranian languages (Persian, Tajik and Dari), status of the izafat and the article is revised. The first one is a specialized affix of the vertex marking of the word in the izafat construction within the word boundaries. The second one not only marks the determination, but at the same time can serve as a link, i.e. as a marker of the vertex position of a noun in a word-combination. But as opposed to the izafat, it is localized outside the word boundaries and forms an analytic word form. Besides that, vocative forms are brought into the paradigm of the noun inflection that are formed from the initial form with the help of affixes and/or intonation and prosody.
