This paper describes the changes that have occurred within the span of 70 years
in the affixes of the nominal predicates of the Chalkan language. The paper considers the comparative paradigms of names in the function of predicates, which were indicated by N. A. Baskakov in his work devoted to the Chalkan language and modern Chalkan language. The author of the present paper lists the phonetic and morphological changes the have occurred in the Chalkan language. It is also noted that the adjectives in the Chalkan Language, when used as predicates, can take plural affixes, although in most Turkic languages the adjective is an invariable part of speech, i.e., in the Turkic languages adjectives acting as attributes or predicates, do not, as a rule, take affixes of number or case. Adjectives as predicates take the same predicational affixes as nouns do.
