Spare pawnbroker after the close of business (7)
I believe the answer is:
slender
'spare' is the definition.
(I've seen this before)
'pawnbroker after the close of business' is the wordplay.
'pawnbroker' becomes 'lender' (I've seen this in another clue).
'after' is a charade indicator (letters next to each other).
'the close of' suggests the final letters (the letter which ends or closes the word).
The final letter of 'business' is 's'.
'lender' put after 's' is 'SLENDER'.
(Other definitions for slender that I've seen before include "Slight in form" , "Shakespearean character" , "Sylphlike" , "Slight, slim" , "remote" .)
