@dodgy,
Hi dodge.
Hope you enjoyed your Friday night out.
Like you I understand both words, epizoon and epizoan, have the same meaning. I checked them at
http://www.onelook.com. This being the case, Lovatts will always accept either words.
As far as the second question is concerned AUTEUR is the correct answer. This one has come up before.
Definition of 'auteur', a film director whose films are so distinctive that he or she is perceived as a film's creator.
Cheers Dutchy.
