A trip's bringing in five loans (8)
I believe the answer is:
advances
'loans' is the definition.
(advancing is a kind of loaning)
'a trip's bringing in five' is the wordplay.
'trip's' becomes 'dance's' (trip can mean to dance).
'bringing in' indicates putting letters inside.
'five' becomes 'V' (roman numeral).
'dances' enclosing 'v' is 'dvances'.
'a'+'dvances'='ADVANCES'
(Other definitions for advances that I've seen before include "Proceeds" , "Moves or puts forward" , "Improvements; moves forwards" , "Moves forwards in a purposeful way" , "Amounts paid before they're earned" .)
