Money for release of Romans (6)
I believe the answer is:
ransom
'money for release' is the definition.
(I've seen this before)
'of romans' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'romans' with letters rearranged gives 'RANSOM'.
(Other definitions for ransom that I've seen before include "Freedom payment" , "Means to release prisoner" , "Money demand" , "Money demanded for the release of a captive" , "Money to get a hostage released" .)
