I was looking at a grammar/style guide for the <b>rules of hyphenation</b> and in it, it had these words and am wondering what exactly they mean?<br/><br/><i>Verb + preposition or adverb (<u>unless closed up or opened in <b>dictionary</b></u> ...</i><br/><br/>My guess is that it means "unless it is formed as one word or split into two words in dictionary."<br/><br/>Sorry but this just came up, why is there no article in front of the word "<b>dictionary</b>"?
