Forming response, Conservative rises (8)
I believe the answer is:
creation
'forming' is the definition.
(act of forming or creating something)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for creation that I've seen before include "Haydn oratorio" , "Act of bringing into being" , "Establishment" , "Act of God" , "Dawn of time" .)
