Bombastic article affected bird? My hat (9)
I believe the answer is:
dithyramb
'bombastic article' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'affected bird? my hat' is the wordplay.
'affected' is an anagram indicator.
'bird'+'my'+'hat'='birdmyhat'
'birdmyhat' with letters rearranged gives 'DITHYRAMB'.
Can you help me to learn more?
(Other definitions for dithyramb that I've seen before include "Song of Ancient Greek" , "old hymn" , "Ecstatic choral hymn" , "poem" , "passionate hymn" .)
