Official announcer in Cork I hear regularly (5)
I believe the answer is:
crier
'official announcer' is the definition.
'crier' can be an answer for 'announcer' (crier is a kind of announcer). I'm unsure of the 'official' bit.
'cork i hear regularly' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'cork'+'i'+'hear'='corkihear'
The alternate letters of 'corkihear' are 'CRIER'.
'in' is the link.
Can you help me to learn more?
(Other definitions for crier that I've seen before include "I call" , "Proclamation maker" , "Public announcer" , "Official making proclamations" , "There once was a town one" .)
