The Persian language has an ancient history and an influential presence in "Mawara-al-Nahr", and especially in current Uzbekistan. A manifestation of this presence can be seen in Place names(toponymy) with Persian roots. Toponymsare place names that have been created throughout history and used to refer to different places. In toponymy, the scientific study of these names is carried out from a historical, geographical, linguistic, etc. point of view. Considering the importance of this point of view in new linguistic research and given the high frequency of Persian place names in the country of Uzbekistan, in this study these place names were examined from the point of view of linguistic construction. First, the names of cities and villages were identified, in which a morpheme or word with Persian roots was identified, and then its grammatical structure was clarified in the structural categories of simple (including free morpheme), compound, derivative and derived-complex names. In this study, we deal little with the history of the development of vocabulary and its historical forms, and given the scope of the topic, most of the words common today were considered.

As a result, it was found that the Persian language had a special influence on the construction of toponyms in this country, and among these toponyms, various linguistic structures are predominantly visible in the structure of compound nouns, derivatives and derived-compound names.
