One uncovered court cases in club (7)
I believe the answer is:
cabaret
'club' is the definition.
(thesaurus)
'one uncovered court cases' is the wordplay.
'one' becomes 'a'.
'uncovered' becomes 'bare' ('bare' can be similar in meaning to 'uncovered').
'court' becomes 'ct'.
'cases' indicates putting letters inside.
'a'+'bare'='abare'
'abare' going inside 'ct' is 'CABARET'.
'in' acts as a link.
(Other definitions for cabaret that I've seen before include "Entertainment provided in a nightclub" , "Evening entertainment as in nightclub" , "In nightspot" , "Floor show and name of great musical" , "Stage show" .)
