This is not an ordinary dictionary. Lots of dictionaries tell you what an 'alligator' is, or how to spell 'balloon' but they won't explain the difference between a 'ringbeller' and a 'trogglehumper', or say why witches need 'gruntles' eggs' or suggest a word for the shape of a 'Knid'. This dictionary does all those things. All the words that Roald Dahl invented are here, like 'biffsquiggled' and 'whizzpopping' to remind you what means what, but that is not all. You'll also find out where words came from, rhyming words, synonyms and lots of alternative words for words that are overused.
