Attraction; tug (4)
I believe the answer is:
pull
I believe this is a double definition.
'attraction' is the first definition.
(I've seen this in another clue)
'tug' is the second definition.
(I've seen this in another clue)
(Other definitions for pull that I've seen before include "Bring out (gun) for use" , "Tell that to the marines" , "Lug, haul" , "Drag" , "withdraw" .)
