Result, consequence (6)
I believe the answer is:
effect
This clue is a double definition.
'result' is the first definition.
(I know that result can be written as effect)
'consequence' is the second definition.
(I know that consequence can be written as effect)
(Other definitions for effect that I've seen before include "Meaning < to force" , "Change produced by action, result" , "Consequential change; state of becoming operative" , "Consequence, outcome" , "Impression produced on spectator" .)
