American woman, Wimbledon winner (4)
I believe the answer is:
ashe
'wimbledon winner' is the definition.
The definition suggests a singular noun which matches the answer.
'american woman' is the wordplay.
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'woman' becomes 'she' ().
'a'+'she'='ASHE'
Can you help me to learn more?
(Other definitions for ashe that I've seen before include "Former tennis star" , "Arthur, who came to court" , "Ex-Wimbledon champ" , "US court star" , "US tennis player Arthur, 1975 Wimbledon champion" .)
