Servant won on the radio (4)
I believe the answer is:
maid
'servant' is the definition.
(maid is a type of servant)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for maid that I've seen before include "One in service" , "Serving girl" , "Young woman - servant" , "employee" , "Female domestic servant" .)
