Maybe it's because English is not my native language, but I'm a bit confused when to use " and when to use '. I know dialogue should use ", so when do we use ' instead? I don't mean ' like I just did with the word don't, but marking words and stuff like that, in lack of a better word. For instance, I have the following sentence in my current boook: He said she would be released 'soon enough'. This isn't dialogue, but 'soon enough' are repeating dialogue. Should there be ' or " in this case? And what are the rules for either outside dialogue?
