Trap revolved around getting suspect seen outside (7)
I believe the answer is:
ensnare
'trap' is the definition.
(to ensnare is to trap or capture)
'around getting suspect seen outside' is the wordplay.
'around' is a reversal indicator.
'getting' becomes 'ran' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'suspect' indicates anagramming the letters (a suspicious or unusual spelling).
'outside' indicates putting letters inside.
'ran' backwards is 'nar'.
'seen' with letters rearranged gives 'ense'.
'nar' inserted into 'ense' is 'ENSNARE'.
'revolved' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for ensnare that I've seen before include "Ambush" , "Capture, trap" , "Catch as if in a trap or net" , "Ecstatic expression of feeling" .)
