Raunchier novel creating terrible storm (9)
I believe the answer is:
hurricane
'terrible storm' is the definition.
'hurricane' can be an answer for 'storm' (hurricane is a kind of storm). I'm not sure about the 'terrible' bit.
'raunchier novel' is the wordplay.
'novel' indicates an anagram (letters in a new or novel order).
'raunchier' with letters rearranged gives 'HURRICANE'.
'creating' is the link.
Can you help me to learn more?
(Other definitions for hurricane that I've seen before include "Tropical cyclone - WWII fighter" , "Caribbean cyclone" , "Severe tropical cyclone" , "Wind force 12 or over on Beaufort scale" , "commotion" .)
