Big Brother's creator (6)
I believe the answer is:
'big brother's creator' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for orwell that I've seen before include "who wrote novels?" , "Socialist author" , "British novelist" , "George .. . . . ., author of 'Animal Farm' and '1984'" , "Author of 1984 etc" .)
