I see one obvious potential for improvement. My word was 'treatise' and I asked for prefixes, and I got things like: hurttreatise.com but that's not a very good domain name because it's ambiguous when spoken whether both words are fully spelled. I think you should be avoiding duplicate letters at word boundaries.
