I'm a little stuck... Click here to teach me more about this clue!

'a labyrinth may cause confusion' is the definition.
I can't tell whether this definition defines the answer.

'a labyrinth' is the wordplay.
'labyrinth' becomes 'maze' (synonyms).
'a'+'maze'='AMAZE'

Can you help me to learn more?

(Other definitions for amaze that I've seen before include "shock" , "Bowl over" , "Greatly surprise, astound" , "wow!" , "Stun" .)

I've seen this clue in the Sydney Morning Herald.
