Energy displayed in court? (5)
I believe the answer is:
drive
I believe this clue is a double definition.
'energy' is the first definition.
(drive can mean energy or enthusiasm)
'court?' is the second definition.
(thesaurus)
'displayed in' is the link.
(Other definitions for drive that I've seen before include "Chauffeur -- force" , "Energy - herd - private road" , "long golf shot" , "Impel; house approach" , "Hit ball with force" .)
