Abstract. In Uzbek language grammar, the use of the possessive affix in connection with the base in the main agreement is a complex phenomenon, and it is said that one of them is syntactic units that are similar in form to the construction of the referent-objective construction, and in terms of the construction of the explanatory-explained construction. Using the fact that the first component in such constructions is similar to the referent, and the second component is similar to the subject, this type of combination is called an interpretative-subjective construction. In this type of explanatory-objective construction, only the third person possessive affix is used, the use of the possessive affix is usually necessary, sometimes the possessive affix finds a facultative case. If the meaning of emphasis is not understood from the second component, then the first component should be judged to be in the main agreement, and if the meaning of ownership is understood, then it should be judged that it is in the nominative agreement. In this case, the demonstrative agreement is in the definite form, of course. In the old Turkish language, nouns take a possessive suffix and express that things and objects belong to one of the three persons. The most popular way of expressing possession is the morphological way. It is expressed in singular and plural by morphological method.
