Saul's loud outcries? (7)
I believe the answer is:
bellows
'outcries?' is the definition.
(bellow is a kind of outcry)
'saul's loud' is the wordplay.
'saul' becomes 'bellow' (novelist Saul Bellow).
'loud' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'bellow'+'s'='BELLOWS'
Can you help me to learn more?
(Other definitions for bellows that I've seen before include "Air blower for fire" , "Fan of fire" , "Shouts loudly" , "sings very loudly" , "Roars at part of the organ" .)
