Game entangled in nets (6)
I believe the answer is:
tennis
'game' is the definition.
(I know that tennis is a type of jeu de paume)
'entangled in nets' is the wordplay.
'entangled' is an anagram indicator.
'in'+'nets'='innets'
'innets' is an anagram of 'TENNIS'.
(Other definitions for tennis that I've seen before include "Popular racquet game - anyone for it?" , "event" , "- elbow; - shoe" , "Medieval, originally French, sport, codified by the British" , "Popular racket game - anyone for it?" .)
