Crossword Genius

An intricate pattern for floor (5)

Ross

I believe the answer is:

'floor' is the definition.
(I've seen this before)

'an intricate pattern' is the wordplay.
'an' becomes 'a'.
'intricate pattern' becomes 'maze'.
'a'+'maze'='AMAZE'

'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".)

I've seen this clue in The Guardian.
