Nightclub held by landlord is coping (5)
I believe the answer is:
disco
'nightclub' is the definition.
(a disco is a club for dancing)
'held by landlord is coping' is the wordplay.
'held by' indicates a hidden word.
'DISCO' is hidden in the letters of 'landlord is coping'.
(Other definitions for disco that I've seen before include "Style of music/dancing" , "Style of pop music" , "equipment for playing recordings" , "Type of music" , "Dancing to records" .)
