Come and go around ancient kingdom (7)
I believe the answer is:
macedon
'ancient kingdom' is the definition.
'macedon' can be an answer for 'kingdom' (I've seen this before). I'm not certain of the 'ancient' bit.
'come and go' is the wordplay.
'go' indicates anagramming the letters (I've seen 'went' mean this ('go' can mean move)).
'come'+'and'='comeand'
'comeand' is an anagram of 'MACEDON'.
'around' is the link.
Can you help me to learn more?
(Other definitions for macedon that I've seen before include "Kingdom of Alexander the Great" , "Philip's place" , "Philip's rule" , "Alexander the Great's country" .)
