Royalist going crazy on his own? (8)
I believe the answer is:
'on his own?' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'royalist going crazy' is the wordplay.
'going crazy' indicates an anagram.
'royalist' is an anagram of 'SOLITARY'.
Can you help me to learn more?
(Other definitions for solitary that I've seen before include "reclusive" , "punishment" , "Secluded, isolated" , "friendless" , "Recluse" .)
