"Incomplete" is the best word to describe this dictionary. I'm Brazilian, and for a native speaker this dictionary is far from "avanado" (meaning "advanced") as its Portuguese title suggests; incidentally in direct opposition to its English title: "Concise Dictionary." I bought it as an aid for a small translation project, and I am disappointed. It doesn't have words such as "mentoring" and "stewardship." I've had to revert to online searches, as I had started, in order to find an adequate translation for several words - a much more cumbersome method. If you need a truly advanced English/Portuguese Portuguese/English dictionary, keep looking; this is not it.
