Minister to deal (5)
I believe the answer is:
serve
This clue is a double definition.
'minister to' is the first definition.
(thesaurus)
'deal' is the second definition.
(thesaurus)
(Other definitions for serve that I've seen before include "Work for; tennis stroke" , "Commence play in tennis" , "Attend; start to play tennis" , "Put the ball in play on court" , "Minister to" .)
