Ramble in a sound country capital (4)
I believe the answer is:
roam
'ramble' is the definition.
(I know that ramble can be written as roam)
'a sound country capital' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
The remaining letters 'rom' 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).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for roam that I've seen before include "Ramble without purpose" , "Wander freely" , "Wander widely" , "Peregrinate" , "Move about aimlessly" .)
