A dictionary (no pronunciation) for parents (who are afraid to ask?) and for non-native speakers who might not have someone to ask. Definitely not scholarly (oooh, that mix-up of your and you're ), and not entirely rational in its organization (a single alphabetic listing would have served better than the subject-related sections e.g. geeky is defined in one section, geek in another). But still, most entries contain examples, the sections have slang-packed dialogs and exercises for practice and self-testing, and the intended audience will find the information fun and useful.
