Party to scowl in misery (6)
I believe the answer is:
dolour
'misery' is the definition.
The definition and answer can be both feelings as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'party to scowl' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'to scowl' becomes 'lour' (lour can mean a scowl or frown).
'do'+'lour'='DOLOUR'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for dolour that I've seen before include "In distress" , "Great sorrow" , "Anguish" , "Woe" , "sadness" .)
