It partly inspired rages (3,3)
I believe the answer is:
red rag
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'partly inspired rages' is the wordplay.
'partly' indicates the answer is hidden within the clue (part of the clue is used).
'RED RAG' can be found hidden inside 'inspired rages'.
Can you help me to learn more?
(Other definitions for red rag that I've seen before include "Gerard (anag) - cause of infuriation" , "It is offensive to a bull" , "Reputed to annoy bull" , "Source of extreme provocation" , "Something proverbially annoying a bull" .)
