How does one write a precis?
A précis is another term for a summary. What is contained in a summary of a literary work depends on the type of work being summarized. The summaries in eNotes study guides are examples of the genre. For most works, the author's name, title of the work, and date, language, and place of composition are included ion the first paragraph.
For a work of fiction, a précis should cover plot, characters, point of view, and tone or genre.
For non-fiction, you might cover viewpoint, central argument, and context.
A précis of a poem should discuss prosody and other literary devices, voice, themes, symbols, and genres.
