Dramatic statement of new ideas (5)
I believe the answer is:
aside
'dramatic statement' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
'new ideas' is the wordplay.
'new' is an anagram indicator.
'ideas' is an anagram of 'ASIDE'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for aside that I've seen before include "Quiet words spoken" , "Actor's line directed solely to audience" , "remark, incidentally" , "Away from main action" , "kept in reserve" .)
