Disagreement voiced on the way down (7)
I believe the answer is:
dissent
'disagreement' is the definition.
(I know that dissent is a type of disagreement)
'voiced on the way down' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
'way' could be 's' (Compass direction - South) and 's' is present in the answer.
'down' could be 'd' and 'd' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dissent that I've seen before include "Objection" , "Opposition" , "Dispute" , "Express disagreement" , "Difference of opinion - snidest (anag)" .)
