Command from stout old soldier (9)
I believe the answer is:
roundhead
'old soldier' is the definition.
(I've seen this before)
'command from stout' is the wordplay.
I cannot really understand how this works, but
'command' could be 'head' (heading is a kind of commanding) and 'head' is located in the answer.
'from' could be 'un' (I've seen this in other clues) and 'un' is found in the answer.
The remaining letters 'rod' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for roundhead that I've seen before include "antimonarchist" , "Parliamentarian (hist.)" , "Supporter of Parliament during the English Civil Wars" , "An enemy of Charles" , "Cavalier's foe" .)
