Back in the same trap, which one finds puzzling (7)
I believe the answer is:
enigmas
'one finds puzzling' is the definition.
I know that 'puzzling' relates to this answer.
'back in the same trap' is the wordplay.
'back' is a reversal indicator.
'in' means one lot of letters goes inside another.
'trap' becomes 'gin' (gin trap is a kind of animal trap).
'same' enclosing 'gin' is 'samgine'.
'samgine' back-to-front is 'ENIGMAS'.
'which' acts as a link.
Can you help me to learn more?
(Other definitions for enigmas that I've seen before include "They're mysterious or difficult to understand" , "'Mysteries, riddles (7)'" , "'Puzzles, riddles (7)'" , "Problems" , "Puzzles - mysteries" .)
