It may end in explosion (8)
I believe the answer is:
'it may end in explosion' is the definition.
The definition suggests a singular noun which matches the answer.
'it may end in explosion' is the wordplay.
'in explosion' is an anagram indicator (I've seen this in other clues).
'itmayend' is an anagram of 'DYNAMITE'.
Can you help me to learn more?
(Other definitions for dynamite that I've seen before include "A1" , "might one be blown away by it?" , "Exciting person - explosive" , "Powerful explosive" , "Nobel's invention" .)
