Writing Exercise #4

“The purpose of the rhetorical precis is to offer a short account of an article that does more than summarize the content. The rhetorical precis, which is four sentences long, accounts for the author and his or her main assertion, the way the author develops or supports the thesis, the author’s purpose in writing, and a description of the intended audience and relationship the author establishes with the audience.

Sentences of the Precis:

  1. Name of author (and credentials or a phrase describing the author), genre and title of work, date in parentheses; a rhetorically accurate verb; and a THAT clause containing the major assertion (thesis) of the work.
  2. An explanation of how the author develops and/or supports the thesis (nature of evidence)
  3. A statement of the author’s apparent purpose, followed by an “in order” phrase.
  4. A description of the intended audience and/or the relationship the author establishes with the audience”
