There is a built-in dictionary in the Outspell game. Our game dictionary is based on the Collins Official Scrabble Words book. 

Based on Collins English Dictionary, this is the most comprehensive Scrabble wordlist ever, including World English from Australia, Canada, New Zealand, South Africa, UK, and the USA brought together in a single list. With more than 279,000 permissible words, including inflected forms, this is the ideal training and adjudication tool for everyone playing Outspell. 

NOTE: In our game, we removed all offensive and dirty words for our customers. 

To check the word is appropriate or not, you can use the game build-in dictionary. Please, find the "Dictionary" button in the right bottom position.

You can type the word you are looking for and check if it persists in the dictionary or not.
