I bought the reference book for my training because our teacher put emphasis on that we buy a monolingual dictionary. Initially walked me to use not so slight of hand, because I'm just used to the words do not come in English or that I simply do not know to search in a bilingual dictionary. Ultimately, however, everything is a matter of habit and so I learned the monolingual dictionary appreciated. Very beneficial one, the explanations come to the words, what meaning they have. For how often you sit in a dilemma and a one word came not, and then the great stammering begins. Here one learns through regular use of the book how words are defined and the more you look the more pure you get a feel to how to apply the definition of words.
