CIA is nonplussed getting involved in boring TV programme! (5,10)
I believe the answer is:
panel discussion
'boring tv programme' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'cia is nonplussed getting involved' is the wordplay.
'getting involved' indicates an anagram (involved can mean confusing or complex).
'cia'+'is'+'nonplussed'='ciaisnonplussed'
'ciaisnonplussed' anagrammed gives 'PANEL DISCUSSION'.
'in' is the link.
Can you help me to learn more?
(Other definitions for panel discussion that I've seen before include "Question Time, perhaps" , "Brains Trust ..." .)
