Lover no longer needing money set out (7)
I believe the answer is:
expound
'set out' is the definition.
(I've seen this before)
'lover no longer needing money' is the wordplay.
'lover no longer' becomes 'ex' (ex-lover).
'needing' means one lot of letters go next to another.
'money' becomes 'pound' (I've seen this in other clues).
'ex'+'pound'='EXPOUND'
(Other definitions for expound that I've seen before include "Explain and interpret" , "Present and explain (a theory)" , "Spell out" , "Explain meaning in detail" , "Put forward detailed argument" .)
