Here is an example of a rhetorical move that connects with ethos: when reading an article about abortion, the author mentions that she has had an abortion. That is an example of an ethical move because the author is creating credibility via anecdotal evidence and first person narrative.
I didn't realize how often ethos is used in writing before reading this article. The example regarding the author having an abortion while writing about abortions will strengthen her credibility. Since she has the experience first hand it is easier to learn and trust her writing.
