I took it because I found it little expensive but in fact it is unusable. 500 pages to present 12000 words. Certainly it is rich (or even too rich, there are words that even French is not often used), but it quickly becomes indigestible. Presentation and bushy poorly ventilated so we did not get to the end of one of the chapters without lifting. Too bad because the cultural notes have interesting air and the numerous sentences to illustrate each word.
