Other aldermen display quality news deliverer (6)
I believe the answer is:
herald
'quality news deliverer' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'other aldermen display' is the wordplay.
'display' indicates a hidden word (I've seen 'displaying' mean this).
'HERALD' is hidden within 'other aldermen'.
Can you help me to learn more?
(Other definitions for herald that I've seen before include "One making proclamations - harbinger" , "Person who announces important news" , "Proclaimer" , "Official crier or messenger" , "Harbinger, precursor" .)
