Animal Farm author (6)
I believe the answer is:
orwell
'animal farm author' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for orwell that I've seen before include "Blair, Eric, d. 1950" , "George .. . . . ., author of 'Animal Farm' and '1984'" , "George --, English author" , "George _______, nom de plume of Eric Blair" , "Writer of 1984" .)
