Sense of grievance private soldier voiced (7)
I believe the answer is:
rancour
'sense of grievance' is the definition.
The definition and answer can be both feelings as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'private soldier voiced' is the wordplay.
'private soldier' becomes 'ranker' (I've seen this before).
'voiced' indicates a 'sounds like' (homophone) clue.
'ranker' is a homophone of 'RANCOUR'.
Can you help me to learn more?
(Other definitions for rancour that I've seen before include "Malicious hostility" , "Feeling of bitterness or dislike" , "Malice" , "Spiteful ill-feeling" , "Acrimony" .)
