Put the fear of God into criminal ring the FBI man arrests (10)
I believe the answer is:
frightened
'put the fear of god' is the definition.
I can't judge whether this defines the answer.
'criminal ring the fbi man arrests' is the wordplay.
'criminal' indicates anagramming the letters.
'fbi man' becomes 'fed' (I can't justify this - if you can you should believe this answer much more).
'arrests' is an insertion indicator.
'ring'+'the'='ringthe'
'ringthe' is an anagram of 'righten'.
'righten' inserted into 'fed' is 'FRIGHTENED'.
'into' acts as a link.
Can you help me to learn more?
(Other definitions for frightened that I've seen before include "Alarmed, unnerved" , "having bad nerves" , "hiding under the table?" , "Having had the wind up" , "Afraid" .)
