Winding or coiling figure (6)

I believe the answer is:

spiral

(Other definitions for spiral that I've seen before include "Sort of staircase (could be vicious?)" , "Shape of a corkscrew or spring" , "Corkscrew curve" , "Corkscrew shape (6)." , "Sir, pal winds in continuous loops" .)

I've seen this clue in The Times.
