Semantic Interpretation and Expressive Effects of the Po-comparatives

In Russian, po- comparatives form a distinct semantic–morphological subgroup within the broader category of comparatives, exhibiting unique meanings and functions. Whereas general comparatives quantify the degree difference between two arguments along a scale, po-comparatives denote a minimal difference in degree. The prefix po- encapsulates the meaning of “slightly more” within a single lexical unit, contrasting with the use of degree adverbs (e.g., ‘slightly,’ ‘a little’) in many other languages. Diachronically, po- derives from a preposition expressing spatial boundaries, which in the comparative domain evolved to mark boundaries of degree, thereby narrowing the perceived difference.<br/> Syntactically, comparatives establish morphological and semantic symmetry between the subject and the standard of comparison, expressed explicitly (via the genitive or chem) or implicitly when omitted. Although po- comparatives occur in both patterns, implicit constructions predominate and often directly modify a preceding noun. Semantically, they extend beyond minimal degree distinctions to convey subjective choice, possibility, or maximal degree, depending on speaker intention and discourse context. In colloquial registers, po- comparatives modulate illocutionary force, functioning to soften or intensify it. Mitigating uses produce a softening effect, while selective uses heighten emphasis. When combined with imperatives, they can serve as a politeness strategy by reducing the addressee’s perceived burden, making them a salient and productive phenomenon in contemporary Russian.
