Lurch; bobbin (4)
I believe the answer is:
reel
I believe this clue is a double definition.
'lurch' is the first definition.
(I know that lurch can be written as reel)
'bobbin' is the second definition.
(I know that bobbin can be written as reel)
(Other definitions for reel that I've seen before include "Folk dance" , "Scottish/Irish dance" , "blows making one do this?" , "Dance; winding cylinder" , "Part of a film; stagger" .)
