In the following article, we analyze the forms of the optative in the Altai language. The modal meaning of volition in the Altai language is expressed by various means: lexical, grammatical, analytical means, and idiomatic constructions. In the article, we offer a brief overview of the means of expression of volition. The primary focus of our study is the desiderative form with =(Ы)ксА=, along with 5 synthetic forms of optative mood: =ГАй, =СА, =(А)йын, =СЫн, =БАзЫн. We show that in the modern Altai language, the finite form with =(Ы)ксА= is widely used in spoken language, with limited compatibility. The form with =(Ы)ксА= is used with the lexical-semantic group of verbs denoting physiological, psychological, or social needs of the subject, for example: јаныкса ʻto want to go homeʼ from the verb јан= ʻto go homeʼ, кӧрӱксе= ʻto want to seeʼ from the verb кӧр= ʻto look’, etc. This form denotes the subject’s strong desire to do something related to their inner feelings and emotions experienced currently and at the moment of speech, or in the past, a desire aimed towards the future which the subject is confident about. Because this form’s semantic compatibility is limited, and the modal meaning of volition expressed by this form is defined as ‘non-locutive’ modality, we believe that it should not, at this stage of the language’s development, be viewed as optative mood, but rather as a non-productive word-forming affix.
