"An interesting editorial cartoon"; is that and oxymoron? Hereinabove is the first sentence of an article I wrote for college. When I received the grade, the teacher said that my use of a semicolon in the opening sentence is incorrect. I just don't see how that is true . . . or, I believe it is a matter of opinion. "An interesting editorial cartoon." Is that an oxymoron? My argument is that if the above sentence is correct, then the former is also correct. Since both of these sentences have the capability of standing alone -- yet are more closely related -- the use of the semicolon pertains probable. I would like to note that: "An interesting editorial cartoon" is not a quote from an actual person. It is just an opening phrase -- if that helps clarify anything since I did not post the whole article.
