Bishop treated badly, looking 'tired'? (8)
I believe the answer is:
battered
'looking 'tired'?' is the definition.
I can't judge whether this defines the answer.
'bishop treated badly' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'badly' is an anagram indicator.
'treated' is an anagram of 'attered'.
'b'+'attered'='BATTERED'
Can you help me to learn more?
(Other definitions for battered that I've seen before include "Hit repeatedly" , "Damaged by repeated blows" , "Pummelled, pounded" , "Injured; like fried fish" , "Like fritters" .)
