Corny sounding puzzle? (4)
I believe the answer is:
maze
'puzzle?' is the definition.
(maze can mean a puzzling situation)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for maze that I've seen before include "Route-finding puzzle" , "Complex network" , "confusion" , "there's no obvious exit from this" , "Complex set of paths" .)
