Suspect solitary enemy of Republican (8)
I believe the answer is:
royalist
'enemy of republican' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'suspect solitary' is the wordplay.
'suspect' indicates an anagram (a suspicious or unusual spelling).
'solitary' with letters rearranged gives 'ROYALIST'.
Can you help me to learn more?
(Other definitions for royalist that I've seen before include "rightwinger?" , "Civil War participant" , "Supporter of monarchy" , "Advocate of the principles of monarchy" , "For queen" .)
