Further back, get in the way of? (6)
I believe the answer is:
hinder
This clue is a double definition.
'further back' is the first definition.
(I've seen this before)
'get in the way of?' is the second definition.
(I've seen this in another clue)
(Other definitions for hinder that I've seen before include "Place obstacles in front of" , "Hamper, impede" , "Keep back by delaying progress" , "Impede, keep back" , "Obstruct; nearer the back" .)
