The author examines semantic-syntactic models of predicates according to Stanislaw Karolak’s conception of semantic-based grammar. From the list of first-order bivalent predicates provided by S. Karolak, the author analyses some of them from the point of view of the number and quality of the implied argument positions. During the analysis it often turns out that more than one model refers to one form of predicate (one signifiant). This phenomenon is due to the polysemous nature of words in natural language and, therefore, to the ambiguity of uses of predicates in different contexts (more than one signifié). In order to determine the number and type of arguments semantically implied by a given predicate, the author applies the test of negation, contraposition, and paraphrase leading to a semantic decomposition and emphasises the role of the metaphor and metonymy in their interpretation.
