A frenetic random communicator (9)
I believe the answer is:
interface
'communicator' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'a frenetic random' is the wordplay.
'random' is an anagram indicator.
'a'+'frenetic'='afrenetic'
'afrenetic' with letters rearranged gives 'INTERFACE'.
Can you help me to learn more?
(Other definitions for interface that I've seen before include "Point where two things interact" , "Point where two thing meet" , "Windows, for example" , "meeting-point" , "Point where two things meet" .)
