@Mitch That makes sense. Perhaps the OP was embarrassed by the question or its (lack of) reception. Why not post a new question, linking to the deleted one? The discussion between you and @Mr.ShinyandNew安宇 would be useful in a Meta post on the subject. I like the idea of a pop-up dictionary / thesaurus if implemented well. One possibility in addition to those already mentioned is to have a list of all the words in a separate box, each linked to its dictionary / thesaurus entry.
