Something that's made Conservative irate, no wild! (8)
I believe the answer is:
creation
'something' is the definition.
(I know that creation is a type of object)
'made conservative irate no wild' is the wordplay.
'made' indicates an anagram.
'conservative' becomes 'C' (UK political abbreviation).
'wild' is an anagram indicator.
'c'+'irate'='cirate'
'cirate' is an anagram of 'creati'.
'no' with letters rearranged gives 'on'.
'creati'+'on'='CREATION'
'that's' is the link.
(Other definitions for creation that I've seen before include "Beginning event" , "Haydn oratorio" , "The bringing into existence of something" , "Act of bringing into being" , "A thing made or invented" .)
