Confused, put another pound in (6)
I believe the answer is:
addled
'confused' is the definition.
(eg drug-addled)
'another pound in' is the wordplay.
'another' becomes 'added' (similar in meaning).
'pound' becomes 'L' (the pound sign is based on an L).
'in' indicates putting letters inside.
'added' placed around 'l' is 'ADDLED'.
'put' acts as a link.
(Other definitions for addled that I've seen before include "Rotten; muddled" , "Baffled - rotten" , "(Of an egg) went bad" , "Scatterbrained like bad egg" , "Completely confused" .)
