A narrative sentence provides clear information about something that happened. It does not include the sequence of events, but it recounts those events, leaving out some occurrences.
To write a mini-narrative or a narrative sentence in the easiest way possible, a writer should try to imitate good one-liners. Replacing the predicates and subjects of excellent one-liners with the writer's own words helps him or her understand the way verbs and nouns form little stories. Writing an epitaph is another effective way to experiment with predicates and subjects to form narrative sentences. A narrative approach gives writers an opportunity to write about themselves, and a narrative sentence should define each writer's point of view.
