Put forward member in new deal (7)
I believe the answer is:
alleged
'put forward' is the definition.
Both the answer and definition are adjectives. Perhaps you can see an association between them that I don't see?
'member in new deal' is the wordplay.
'member' becomes 'leg' (member can mean a limb).
'in' means one lot of letters goes inside another.
'new' indicates anagramming the letters.
'deal' with letters rearranged gives 'aled'.
'leg' placed within 'aled' is 'ALLEGED'.
Can you help me to learn more?
(Other definitions for alleged that I've seen before include "So-called" , "Asserted in court" , "Claimed (without proof)" , "Declared but not proved; maintained" , "Asserted - unproven" .)
