Stagger out of 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' ('maze' can be a synonym of 'labyrinth').
'a'+'maze'='AMAZE'
'out of' acts as a link.
(Other definitions for amaze that I've seen before include "Bowl over" , "Dumbfound" , "Confound with wonder" , "Stun" , "Flabbergast" .)
