Suit jackets pale, worn in dingy cinema (7)
I believe the answer is:
fleapit
'dingy cinema' is the definition.
'fleapit' can be an answer for 'cinema' (fleapit is a kind of cinema). I am not certain of the 'dingy' bit.
'suit jackets pale worn' is the wordplay.
'suit' becomes 'fit' (synonyms).
'jackets' is an insertion indicator.
'worn' indicates an anagram (worn can mean damaged).
'pale' is an anagram of 'leap'.
'fit' placed around 'leap' is 'FLEAPIT'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for fleapit that I've seen before include "jumper" , "Scruffy cinema" , "Run-down place for pictures" , "Run-down cinema" , "Shabby old cinema" .)
