Consequently, those people are in favour of being heard (9)
I believe the answer is:
therefore
'consequently' is the definition.
(I've seen this before)
'those people are in favour of being heard' is the wordplay.
'those people are' becomes 'there' (I can't justify this - if you can you should give a lot more credence to this answer).
'in favour of' becomes 'for' (being for a particular cause).
'being heard' shows a homophone (sound like).
'for' sounds like 'fore'.
'there'+'fore'='THEREFORE'
Can you help me to learn more?
(Other definitions for therefore that I've seen before include "as result" , "has a triangular formation in maths?" , "Thus" , "Ergo" , "In consequence" .)
