Journalist going to a club cooled off (6)
I believe the answer is:
abated
'cooled off' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Perhaps you can see a link between them that I don't see?
'journalist going to a club' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'going to' is a charade indicator (letters next to each other).
'club' becomes 'bat' (as in sporting equipment).
'a'+'bat'='abat'
'ed' after 'abat' is 'ABATED'.
Can you help me to learn more?
(Other definitions for abated that I've seen before include "Decreased, receded" , "grew smaller" , "Calmed like storm" , "Became less intense" , "Went down or became less, like storm" .)
