Some questions of this form might be better off at English Language & Usage or English Language Learners, though.1 Before posting your question, you might want to think about whether it's more a language question or a literature question. If you're asking about the meaning of a word or phrase, one of the language sites might be the best place to ask. If you're asking about what an author was trying to say by a word or phrase whose meaning you know in general, then definitely ask it here.
