Half contradicted mean and beastly outburst (6)
I believe the answer is:
bellow
'beastly outburst' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'half contradicted mean' is the wordplay.
'half' suggests halving the letters.
'contradicted' becomes 'belied' ('belie' can be a synonym of 'contradict').
'mean' becomes 'low' (both can mean nasty or dishonourable).
'belied' with half the letters taken is 'bel'.
'bel'+'low'='BELLOW'
'and' is the link.
Can you help me to learn more?
(Other definitions for bellow that I've seen before include "Loud and deep roar" , "Shout; Saul --, novelist" , "Roar loudly" , "Roar like a bull" , "Loud deep sound as by bull" .)
