Intense part of standard entertainment (6)
I believe the answer is:
ardent
'intense' is the definition.
(thesaurus)
'part of standard entertainment' is the wordplay.
'part of' indicates a hidden word.
'ARDENT' is hidden in the letters of 'standard entertainment'.
(Other definitions for ardent that I've seen before include "Loving and fiery" , "full of zeal" , "Having great warmth of feeling like a lover" , "very interested" , "Intensely devoted" .)
