In the newsletter of The Book Depository I came across an excerpt of an article which is available on Harper’s Magazine. The full article is only available for subscribers, but what is there for everybody is pretty good, too. It is called Words into hype, part of The Offutt Guide to Literary Terms, by author Chris Offutt.
I particularly like the definition of
prose poem: either a poem with no line breaks or a lyric essay with no indentation. No one knows.
