A Study of Some Garmmatical forms in the Language

The article deals with the study of the Uzbek forms -dek // -day, -cha.  In Uzbek linguistics, the different interpretations of these suffixes in several sources show differences of opinion about it.  There is no comprehensive research on these grammatical forms, which are evaluated as adjective-forming derivative morphemes, form-forming derivative morphemes, lexical form-forming morphemes, lexical-syntactic forms, or affix-auxiliaries.  The essence of these grammatical forms has been revealed on the basis of earlier views and on the basis of personal conclusions.  The auxiliary features of the forms -dek // -day, -cha are also described in detail.  The ideas were also substantiated using examples from the work of art.
