Confidence from fresh ideas (5)
I believe the answer is:
aside
'confidence' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'fresh ideas' is the wordplay.
'fresh' indicates anagramming the letters.
'ideas' with letters rearranged gives 'ASIDE'.
'from' is the link.
Can you help me to learn more?
(Other definitions for aside that I've seen before include "Privately, apart" , "(Pushed) out of the way" , "Aides (anag.)" , "Where one's taken for intimacy" , "Whispered comment" .)
