Discourage delay (3,3)
I believe the answer is:
put off
This clue is a double definition.
'discourage' is the first definition.
(putting off is a kind of discouraging)
'delay' is the second definition.
(putting off is a kind of delaying)
(Other definitions for put off that I've seen before include "Postpone or dissuade" , "Deter; deterred" , "Deter; postpone" , "Postpone; distract" , "Postpone - disconcert" .)
