What winds up third eager man (5)
I believe the answer is:
david
'man' is the definition.
(I know that David is a King of Rome)
'what winds up third eager' is the wordplay.
I cannot quite understand how this works, but
'eager' could be 'avid' (synonyms) and 'avid' is present in the answer.
A single letter 'd' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for david that I've seen before include "Boy's name" , "singer/harpist?" , "Goliath's slayer" , "Camp" , "Hebrew king" .)
