Wanting too much golf, does have to step back (5)
I believe the answer is:
greed
'wanting too much' is the definition.
(I've seen this before)
'golf does have to step back' is the wordplay.
I cannot really see how this works, but
'golf' could be 'g' (phonetic alphabet: alpha, bravo, charlie etc.) and 'g' is found within the answer.
The remaining letters 'reed' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for greed that I've seen before include "Avidity" , "Circuit" , "Rapacity" , "Vice" , "Gluttony" .)
