Winner at court remains for hearing (4)
I believe the answer is:
ashe
'winner at court' is the definition.
I can't judge whether this definition defines the answer.
'remains for hearing' is the wordplay.
'remains' becomes 'ash' (remains of a fire).
'for hearing' indicates a 'sounds like' (homophone) clue.
'ash' sounds like 'ASHE'.
Can you help me to learn more?
(Other definitions for ashe that I've seen before include "US tennis player Arthur, 1975 Wimbledon champion" , "He was good enough to win Wimbledon" , "US rallying champion" , "Former tennis star" , "tennis champ" .)
