On radio man would listen (4)
I believe the answer is:
heed
'listen' is the definition.
(I know that listen can be written as heed)
'on radio man would' is the wordplay.
I cannot quite see how this works, but
'man' could be 'he' (pronoun for a man) and 'he' is present in the answer.
'would' could be 'd' (I've seen this in other clues) and 'd' is found in the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for heed that I've seen before include "Regard" , "Be mindful of" , "Take notice of" , "Mark" , "Consider" .)
