Writer needing men in good health (6)
I believe the answer is:
Here is my best explanation:
'writer' is the definition.
'men in good health' is the subsidiary indication.
'men' becomes 'or' (I've seen this in other clues).
'in good health' becomes 'well' ('well' can be similar in meaning to 'in good health').
'needing' is the link.
(Other definitions for orwell that I've seen before include "George -, nineteen eighty-four author", "Nineteen eightyfour author", "George --, English author", "George --, British author", "George . . . . . ., writer concerned with social justice", "George ...... wrote 'Animal Farm' and '1984'", "George .. . . . ., author of 'Animal Farm' and '1984'", "Eric Arthur Blair", "Wrote Animal Farm" and "George _______, nom de plume of Eric Blair".)
