Murmur dopy chap only half regarded Dublin-born novelist and philosopher, brought up in Britain (7)
I believe the answer is:
murdoch
'murmur' is the definition.
Both the answer and definition are singular nouns.
Maybe there's a link between them I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for murdoch that I've seen before include "Media mogul" , "Rupert --, media owner" , "Press baron" , "Author of The Bell" , "Rupert --; Iris --" .)
