Sally learned this:
“Op-ed does not mean “opinion-editorial” – it literally means it’s opposite the editorial page!”
She pointed out that Wikipedia says:
“An op-ed, abbreviated from opposite the editorial page (though often mistaken for opinion-editorial), is a newspaper article that expresses the opinions of a named writer who is usually unaffiliated with the newspaper’s editorial board. These are different from editorials, which are usually unsigned and written by editorial board members.”
