Case frames of interpretation predicates and compression mechanisms
Predicates of interpretation are abstract predicates. They have a valency of the situation (prepositional valency). Other classes of abstract predicates (perceptual, mental, speech) express their propositional valency by subordinate clause. Interpretation and interpreted situation can be expressed in separate sentences. But they can also form a unitary construction by compression. In this case propositional valency of interpretation predicates is expressed by case-form or by prepositional phrase. The article considers the forms «v + prepositional case» and instrumental case, cf.: prodvinut’sya v rassledovanii (‘to move forward in the investigation’); vydeliat ’sya eruditsiey (‘stand out/excel in erudition’).
