Hitch, delay (7)
I believe the answer is:
setback
I believe this clue is a double definition.
'hitch' is the first definition.
(I've seen this before)
'delay' is the second definition.
(thesaurus)
(Other definitions for setback that I've seen before include "unfortunate event" , "Reverse" , "Snag" , "disappointment" , "Check" .)
