An intricate pattern for floor (5)
'floor' is the definition.
(I've seen this before)
'an intricate pattern' is the wordplay.
'an' becomes 'a'.
'intricate pattern' becomes 'maze'.
'for' acts as a link.
(Other definitions for amaze that I've seen before include "Stagger", "Bewilder", "Affect with wonder", "Greatly surprise, fill with wonder", "shock".)
