Stagger from a labyrinth (5)
I believe the answer is:
amaze
'stagger' is the definition.
(I've seen this before)
'a labyrinth' is the wordplay.
'labyrinth' becomes 'maze' (synonyms).
'a'+'maze'='AMAZE'
'from' acts as a link.
(Other definitions for amaze that I've seen before include "Stupefy" , "Greatly surprise, fill with wonder" , "Stun" , "Flummox" , "Bowl over" .)
