the semantic content of a clause, separately from whether it is packaged as topic–comment, thetic, or identificational. Propositional content corresponds basically to 'who did what to whom'. Example: In There's a coyote running down the street!, It's a coyote that's running down the street, and The coyote is running down the street, the propositional content shared by the thetic, identificational, and topic–comment constructions, respectively, is the current running event with a coyote as the runner and the street as the location of the running.
