Force to stop a rake and villain (5)
I believe the answer is:
rogue
'villain' is the definition.
(rogue is a kind of villain)
'force to stop a rake' is the wordplay.
'force' becomes 'g' (short for gravity).
'to stop' means one lot of letters goes inside another.
'a rake' becomes 'roue' (both can mean an immoral man).
'g' inserted within 'roue' is 'ROGUE'.
'and' acts as a link.
(Other definitions for rogue that I've seen before include "Villain - freak" , "Diseased plant" , "Chap in gallery" , "Profligate" , "Unprincipled man" .)
