The research object of the dissertation is the current conceptual and descriptive models in Evaluative Morphology studies, while the research question can be formulated as follows: what descriptive elements should contain an analytical framework that may be applicable cross-linguistically for the description and quantification of Evaluative Morphology resources in natural languages? In turn, the particular research subject of the dissertation is the Evaluative Morphology resources of Spanish and Latvian. The intended aim of this work is to develop an analytic framework that accounts for the morphosemantic features of evaluative forms in view to obtain measurable parameters that can be applied in descriptive, as well as contrastive, studies of evaluative morphology in a variety of languages.
