Bound to wear suit for cinema (7)
I believe the answer is:
fleapit
'cinema' is the definition.
(fleapit is a kind of cinema)
'bound to wear suit' is the wordplay.
'bound' becomes 'leap' ('leap' can be a synonym of 'bound'**).
'to wear' is an insertion indicator.
'suit' becomes 'fit' ('fit' can be a synonym of 'suit').
'leap' placed inside 'fit' is 'FLEAPIT'.
'for' is the link.
(Other definitions for fleapit that I've seen before include "shabby public building" , "Run-down place for pictures" , "dive?" , "Run-down cinema" , "jumper" .)
