The article reveals one of the aspects of formation of the terminological system of the grammar of estimation. The term tonality is characterized, and variants of its interpretation in the researched direction are described. The modelling of estimative tonality is illustrated on the example of using verb forms (imperative, indicative, infinitive) with imperative meaning; the expression of estimative meanings is argued through the interaction of semantics of categoricalness, rudeness, alienation and negative estimation.
