Blair, when writing, wore out Liberals (6)
I believe the answer is:
orwell
'blair' is the definition.
(I've seen this before)
'wore out liberals' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'liberals' becomes 'll' (a political abbreviation for liberal written twice).
'wore' with letters rearranged gives 'orwe'.
'orwe'+'ll'='ORWELL'
'when writing' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for orwell that I've seen before include "George -, nineteen eighty four author" , "Blair, Eric, d. 1950" , "George .. . . . ., author of 'Animal Farm' and '1984'" , "George ...... wrote 'Animal Farm' and '1984'" , "George _______, nom de plume of Eric Blair" .)
