Character in rage meant to explode (11)
I believe the answer is:
temperament
'character' is the definition.
(I've seen this before)
'rage meant to explode' is the wordplay.
'rage' becomes 'temper' (I've seen this before).
'to explode' indicates anagramming the letters.
'meant' with letters rearranged gives 'ament'.
'temper'+'ament'='TEMPERAMENT'
'in' acts as a link.
(Other definitions for temperament that I've seen before include "Disposition; tuning adjustment" , "Personality" , "A person's nature as it affects behaviour" , "Piano tuning; character" , "Frame of mind" .)
