Follower of a cause (6)
I believe the answer is:
effect
This clue could be a double definition.
'follower' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'a cause' is the second definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'of' is the link.
Can you help me to learn more?
(Other definitions for effect that I've seen before include "Change produced by impact or other cause" , "Consequential change; state of becoming operative" , "Result of action, or cause to happen" , "Consequence, outcome" , "Accomplish - result" .)
