Profligate poet? (7)
I believe the answer is:
spender
I believe this is a double definition.
'profligate' is the first definition.
(spender is a kind of profligate)
'poet?' is the second definition.
(Stephen Spender)
(Other definitions for spender that I've seen before include "One using money" , "poet, communist" , "writer of poetry" , "who is just 31[WINDOW SHOPPER]? No" , "One who disburses money - big in popular song" .)
