Our dictionary currently uses roughly 160,000 words selected from the Princeton WordNet dictionary (citation below), from the Webster’s Unabridged Dictionary as made available by Project Gutenberg, from the Linux English dictionary (distributed with Ubuntu and other projects), and words as requested by Speedily users.
