Explosive made tiny fragments (8)
I believe the answer is:
dynamite
'explosive' is the definition.
(I've seen this before)
'made tiny fragments' is the wordplay.
'fragments' indicates anagramming the letters.
'made'+'tiny'='madetiny'
'madetiny' anagrammed gives 'DYNAMITE'.
(Other definitions for dynamite that I've seen before include "Nitroglycerine explosive" , "May end it with explosive" , "might one be blown away by it?" , "Tiny dame (anag)" , "an exciting thing" .)
