Stand in the way of (6)
I believe the answer is:
stymie
'stand in the way of' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for stymie that I've seen before include "Obstruction (originally at golf)" , "Tricky situation" , "'Hinder, obstruct (6)'" , "Obstruct as on putting green" , "Frustrate" .)
