a strategy found for the expression of thetic constructions. In a split structure, the information normally expressed as the comment or predicate in a topic--comment construction may be expressed in a different form, usually some sort of subordinate clause-like form. The information normally expressed as the topic in the topic--comment construction may be expressed in a different form, usually with a presentational construction; or both types of information are expressed differently.
