This book has several advantages: 1, it has a lot of set phrases which are quite difficult to find in the LSJ dictionary. 2, it tells you the frequency of the word by putting frequent words in large font. 3, it alerts you to verbs and nouns of irregular declension and conjugation. 4, most important of all, this book recognizes that words are more easily remembered if they are situated within a network. This book divides words into 38 networks and then further subdivides them again into usually between 10 and 20 categories. It is far easier to remember words when you see them coalesce within a group.
It’s worth mentioning that it’s a vocabulary rather than dictionary, and it’s about AD Greek.
I think this is an admirable effort on Adrian Hundhausen’s part. The format I do find at moments confusing –– and it lacks extensive examples of usage from the corpus. LSJ and Montanari then remain my mainstays, but a one-man unfunded and self-published vocabulary is still something to marvel at.
