Shipmate finally notices missing loop in lures (7)
I believe the answer is:
entices
'lures' is the definition.
(I know this)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for entices that I've seen before include "Persuades with pleasant offer" , "Lures or beguiles" , "'Lures, tempts (7)'" .)
