So serve a new spell abroad (8)
I believe the answer is:
overseas
'abroad' is the definition.
(both can mean in another country)
'so serve a new' is the wordplay.
'new' indicates an anagram.
'so'+'serve'+'a'='soservea'
'soservea' with letters rearranged gives 'OVERSEAS'.
'spell' acts as a link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for overseas that I've seen before include "In a foreign country" , "Exotic" , "abroad - with 12a" , "In foreign parts" .)
