Pretend to move? (6)
I believe the answer is:
affect
I believe this is a double definition.
'pretend to' is the first definition.
(thesaurus)
'move?' is the second definition.
(I know that move can be written as affect)
(Other definitions for affect that I've seen before include "Make a difference to" , "Pretend - to have influence on events" , "Assume" , "It always has a cause" , "Have impact upon" .)
