Overwrought, always being caught by FBI agent (7)
I believe the answer is:
fevered
'overwrought' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?
'always being caught by fbi agent' is the wordplay.
'always' becomes 'ever' (synonyms).
'being caught by' indicates putting letters inside.
'fbi agent' becomes 'fed' (short for federal agent).
'ever' inserted into 'fed' is 'FEVERED'.
Can you help me to learn more?
(Other definitions for fevered that I've seen before include "Nervously excited" , "Impatient" , "Highly excited" .)
