Boogle includes a dictionary that contains thousands of words. However, it is possible that you may try entering a word that isn’t in the dictionary. It is also possible that Boogle may accept a word that shouldn’t be in the dictionary.
As of now, there is no way for users to edit the words in the dictionary. If enough interest is shown, this may be implemented in the future. For now, you might want to check the website to see if there are any updates to the dictionary available. If you have come across a word that should (or shouldn’t) be in the dictionary, please send an e-mail.
