Churchill edited content in a relaxed manner (7)
I believe the answer is:
chilled
'relaxed manner' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Maybe you can see a link between them that I don't see?
'churchill edited content' is the wordplay.
'content' indicates the answer is hidden within the clue (letters contained within the clue).
'CHILLED' is hidden in the letters of 'churchill edited'.
'in a' is the link.
Can you help me to learn more?
(Other definitions for chilled that I've seen before include "Made cold" , "Kept very cold" , "Cooled" , "Horrified" .)
