Tennis champion's good service (4)
I believe the answer is:
real
I believe this clue is a quadruple definition!!
'tennis' is the first definition.
(real tennis is a kind of tennis)
'champion's' is the second definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'good' is the third definition.
(thesaurus)
'service' is the fourth definition.
(I know that real is a currency)
Can you help me to learn more?
(Other definitions for real that I've seen before include "Genuine or existing" , "Actual, concrete" , "Pukka" , "Actual; Brazilian currency" , "foreign currency" .)
