This wonderful dictionary is so good that it really feels like cheating. If you think you know the defining word in a clue, look it up in this dictionary. It sorts the possible synonyms into word length and then alphabetically. It beats Roget hands down and is much quicker to use.
For example, if the answer is a girl's name, look up "girl" and it will give over a page of names from "Di" (2 letters) to "Wilhelmina" (10 letters). Did you know that there was a dance called a "boogaloo"? I didn't; but its in the book.
We use this book when stuck on the Guardian Cryptic crossword. This is the quick and easy way to finish off your crossword.
