Sort of air possibly found in hop yards (8)
I believe the answer is:
rhapsody
'sort of air' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'found in hop yards' is the wordplay.
'found in' indicates anagramming the letters.
'hop'+'yards'='hopyards'
'hopyards' anagrammed gives 'RHAPSODY'.
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for rhapsody that I've seen before include "Ecstatic written or romantic musical composition" , "Ecstatic utterance" , "Gershwin wrote of one in blue" , "'''... in Blue'' (Gershwin) (8)'" , "Ecstatic piece" .)
