Correct catches fitting trap (7)
I believe the answer is:
capture
'trap' is the definition.
(I know this)
'correct catches fitting' is the wordplay.
'correct' becomes 'cure' (I can't justify this - if you can you should believe this answer much more).
'catches' is an insertion indicator.
'fitting' becomes 'apt' (I've seen this before).
'cure' placed around 'apt' is 'CAPTURE'.
Can you help me to learn more?
(Other definitions for capture that I've seen before include "Take prisoner" , "Take by force" , "Ensnare" , "Apprehend" , "Take opponent's piece (chess)" .)
