Deter or defer (3,3)
I believe the answer is:
put off
I believe this is a double definition.
'deter' is the first definition.
(thesaurus)
'defer' is the second definition.
(synonyms)
'or' acts as a link.
(Other definitions for put off that I've seen before include "Deter; deterred" , "Deter; postpone" , "Defer - deter" , "Postpone or dissuade" , "Defer to a later time, or alienate" .)
