In an effort to continue to as green as possible, I'm offering this resource through this blog while we study Martin Luther King's "Letter from Birmingham Jail." What you will find here is access to a Word document where the different rhetorical appeals are identified throughout the letter; they are color-coded. Perhaps this will aid you in your analysis. This document can be found here .
Used to be a blog for AP English Language and Composition, but now has transcended beyond that.
