Prosey

Lord Dunorven was on the floor, talking a long, prosey speech, in which neither himself nor any one else seemed to be in the least interested.

Beginning writers tend to follow this pattern, putting the main clause first just as they would in speech. Often, putting it last can make for more suspense and so help give life to what would otherwise be dull and prosey.

From among other possible thin-layered objects, the newspaper is chosen as a hyperbole of prosey writing, and slate is prose compared to marble.
