Audibly crude bellow (4)
I believe the answer is:
roar
This clue could be a double definition.
'audibly crude' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'bellow' is the second definition.
('roar' can be a synonym of 'bellow')
Can you help me to learn more?
(Other definitions for roar that I've seen before include "Loud noise of angry bull" , "The __ of the Greasepaint -- The Smell of the Crowd (1964 musical)" , "Make a loud noise" , "Great cry" , "Jaguar, for example, emits this" .)
