Some Cervantes revolutionary characters capable of getting heated and blowing top (4)
I believe the answer is:
etna
'characters capable of getting heated and blowing top' is the definition.
I can't judge whether this definition defines the answer.
'some cervantes revolutionary' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'revolutionary' says the letters should be written in reverse.
'ante' can be found hidden inside 'cervantes'.
'ante' written backwards gives 'ETNA'.
Can you help me to learn more?
(Other definitions for etna that I've seen before include "Impressive mount" , "Volcano; reverse of stake" , "Dangerous peak" , "Active European volcano" , "Sicilian volcano" .)
