September is Be Kind to Writers and Editors Month, which reminded me of an old question: Is copy editor one word or two?
As with so many compound words, either form works; some dictionaries list it both ways. The AP Stylebook says copy editor is two words just like business editor and managing editor. A Google search and a Google News search also both return far more results for the two-word version, and the Merriam-Webster Online Dictionary lists only the two-word form. Perhaps most tellingly, the American Copy Editors Society presents it as two words.
I can't say copyeditor is wrong, but I recommend copy editor.
