Blazing, I fear destroyed (5)
I believe the answer is:
afire
'blazing' is the definition.
(synonyms)
'i fear destroyed' is the wordplay.
'destroyed' is an anagram indicator.
'i'+'fear'='ifear'
'ifear' with letters rearranged gives 'AFIRE'.
(Other definitions for afire that I've seen before include "Alight" , "Burning" , "Blazing - excited" , "lit up" , "in flames" .)
